CVE-2019-11244 (GCVE-0-2019-11244)

Vulnerability from cvelistv5 – Published: 2019-04-22 14:54 – Updated: 2024-08-04 22:48

Title
kubectl creates world-writeable cached schema files
Summary
In Kubernetes v1.8.x-v1.14.x, schema info is cached by kubectl in the location specified by --cache-dir (defaulting to $HOME/.kube/http-cache), written with world-writeable permissions (rw-rw-rw-). If --cache-dir is specified and pointed at a different location accessible to other users/groups, the written files may be modified by other users/groups and disrupt the kubectl invocation.
Severity

CVE-2019-9495 (GCVE-0-2019-9495)

Vulnerability from cvelistv5 – Published: 2019-04-17 13:31 – Updated: 2024-08-04 21:54

Title
The implementations of EAP-PWD in hostapd and wpa_supplicant are vulnerable to side-channel attacks as a result of cache access patterns
Summary
The implementations of EAP-PWD in hostapd and wpa_supplicant are vulnerable to side-channel attacks as a result of cache access patterns. All versions of hostapd and wpa_supplicant with EAP-PWD support are vulnerable. The ability to install and execute applications is necessary for a successful attack. Memory access patterns are visible in a shared cache. Weak passwords may be cracked. Versions of hostapd/wpa_supplicant 2.7 and newer, are not vulnerable to the timing attack described in CVE-2019-9494. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.
Severity
No CVSS data available.

CVE-2019-9494 (GCVE-0-2019-9494)

Vulnerability from cvelistv5 – Published: 2019-04-17 13:31 – Updated: 2024-08-04 21:54
VLAI
Title
The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side-channel attacks
Summary
The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.
Severity
No CVSS data available.

Summary
Kubernetes Unsafe Cacheing
Details

In Kubernetes v1.8.x-v1.14.x, schema info is cached by kubectl in the location specified by --cache-dir (defaulting to $HOME/.kube/http-cache), written with world-writeable permissions (rw-rw-rw-). If --cache-dir is specified and pointed at a different location accessible to other users/groups, the written files may be modified by other users/groups and disrupt the kubectl invocation.

Vulnerability from github – Published: 2026-04-28 22:28 – Updated: 2026-05-08 13:42

Summary
Fiber's cache middleware default key generator ignores query string, causing response mix-up across distinct query parameters
Details

Summary

Fiber cache middleware's default key generator uses only c.Path() and does not include the query string. As a result, requests like /?id=1 and /?id=2 can map to the same cache key and share the same cached response.

This can cause response mix-up (cache poisoning-like behavior) for endpoints where response content depends on query parameters.

Details

Default configuration in cache middleware:

  • KeyGenerator: func(c fiber.Ctx) string { return utils.CopyString(c.Path()) }

References: - https://github.com/gofiber/fiber/blob/main/middleware/cache/config.go#L90-L92 - https://github.com/gofiber/fiber/blob/main/middleware/cache/cache_test.go#L599-L621

The existing test demonstrates that when handler output depends on query parameter id, a second request with a different query still returns the first cached response (cache hit), confirming query is not part of the default cache key.

PoC

Minimal PoC:

package main

import (
    "log"

    "github.com/gofiber/fiber/v3"
    "github.com/gofiber/fiber/v3/middleware/cache"
)

func main() {
    app := fiber.New()
    app.Use(cache.New()) // default config

    app.Get("/", func(c fiber.Ctx) error {
        return c.SendString(c.Query("id", "1"))
    })

    log.Fatal(app.Listen(":3000"))
}

Reproduction:

  1. GET /?id=1
  2. Cache miss
  3. Response body: 1
  4. GET /?id=2
  5. Cache hit
  6. Response body: 1 (expected 2)

Local verification command used:

go test ./middleware/cache -run Test_Cache_WithNoCacheRequestDirective -count=1

Observed result: test passes, confirming this is current behavior.

Impact

  • Responses that should vary by query parameters can be mixed between requests.
  • In real deployments, this may leak or corrupt user/tenant-specific content if query parameters influence context or data selection.
  • This is deployment-dependent but security-relevant, and not safe-by-default for query-variant responses.

Suggested remediation

  • Change default cache key generation to include path + normalized query string (or canonicalized original URL).
  • Keep ability for custom key generators.
  • Add explicit documentation warning that path-only keying is unsafe for query-dependent responses.

Mitigation
Architecture and Design

Protect information stored in cache.

Mitigation
Architecture and Design

Do not store unnecessarily sensitive information in the cache.

Mitigation
Architecture and Design

Consider using encryption in the cache.

CAPEC-204: Lifting Sensitive Data Embedded in Cache

An adversary examines a target application's cache, or a browser cache, for sensitive information. Many applications that communicate with remote entities or which perform intensive calculations utilize caches to improve efficiency. However, if the application computes or receives sensitive information and the cache is not appropriately protected, an attacker can browse the cache and retrieve this information. This can result in the disclosure of sensitive information.
