Title
MessagePack-Java Vulnerable to Remote Denial of Service via Malicious .msgpack Model File Triggering Unbounded EXT Payload Allocation
Summary
MessagePack for Java is a serializer implementation for Java. A denial-of-service vulnerability exists in versions prior to 0.9.11 when deserializing .msgpack files containing EXT32 objects with attacker-controlled payload lengths. While MessagePack-Java parses extension headers lazily, it later trusts the declared EXT payload length when materializing the extension data. When ExtensionValue.getData() is invoked, the library attempts to allocate a byte array of the declared length without enforcing any upper bound. A malicious .msgpack file of only a few bytes can therefore trigger unbounded heap allocation, resulting in JVM heap exhaustion, process termination, or service unavailability. This vulnerability is triggered during model loading / deserialization, making it a model format vulnerability suitable for remote exploitation. The vulnerability enables a remote denial-of-service attack against applications that deserialize untrusted .msgpack model files using MessagePack for Java. A specially crafted but syntactically valid .msgpack file containing an EXT32 object with an attacker-controlled, excessively large payload length can trigger unbounded memory allocation during deserialization. When the model file is loaded, the library trusts the declared length metadata and attempts to allocate a byte array of that size, leading to rapid heap exhaustion, excessive garbage collection, or immediate JVM termination with an OutOfMemoryError. The attack requires no malformed bytes, user interaction, or elevated privileges and can be exploited remotely in real-world environments such as model registries, inference services, CI/CD pipelines, and cloud-based model hosting platforms that accept or fetch .msgpack artifacts. Because the malicious file is extremely small yet valid, it can bypass basic validation and scanning mechanisms, resulting in complete service unavailability and potential cascading failures in production systems. Version 0.9.11 fixes the vulnerability.

Summary
Uncontrolled resource consumption for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow a denial of service. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts.

Title
MISP Missing Authorization on Template File Upload Allows Authenticated Disk Exhaustion
Summary
Affected versions of MISP allow any authenticated user to access TemplatesController::uploadFile() because the ACL entry for templates/uploadFile used the wildcard *. This bypasses the intended role restrictions applied to neighboring template-management operations.
The upload handler accepts arbitrary content with only minimal checks and writes it into app/tmp/files/. A low-privileged or read-only user can therefore repeatedly upload files and consume server disk space without requiring perm_add or perm_template. The fix changes the ACL requirement from * to perm_add.
The commit also rules out stronger impacts: uploaded files receive random names, path traversal/predictable overwrite is not available, the temporary directory is outside the web root, and the files are not directly served over HTTP. Therefore, the issue should not be described as arbitrary file overwrite, stored XSS, or RCE.

Title
MISP Unthrottled Authentication Failure Log Writes Enable Resource Exhaustion
Summary
Affected versions of MISP do not consistently apply the existing authentication-failure logging throttle.
Two API authentication failure branches wrote directly to the Log model:
- API requests with no authentication key;
- requests supplying an API key with an incorrect length
Unlike other authentication failures, these paths bypassed _shouldLog(), so every request could create another durable auth_fail entry.

fix: [logging] Throttle the two unguarded auth_fail writes | db6f78e69079… |
Fix summary
The fix applies the existing hourly per-key log throttle to the two previously unguarded authentication-failure log writes. The throttle key is now derived from the client's source IP address rather than from caller-supplied input, preventing an attacker from generating unbounded Redis throttle entries. A per-request memo (stored in Configure::read('CurrentRequestAuthFailKeys')) is added to _shouldLog() to prevent duplicate log entries when beforeFilter() executes a second time via CakeErrorController on an exception, ensuring one request produces at most one log entry per key regardless of the operator's log_each_individual_auth_fail setting.
Patch summary
In app/Controller/AppController.php: (1) The 'no authkey' branch in beforeFilter() now calls _shouldLog('noauthkey:' . $this->User->_remoteIp()) before writing the log entry. (2) The 'incorrect length' branch in __loginByAuthKey() now calls _shouldLog('badauthkeylength:' . $this->User->_remoteIp()) before writing the log entry. (3) _shouldLog() is refactored to first check a per-request memo array (Configure 'CurrentRequestAuthFailKeys') to suppress duplicate logging across the double beforeFilter() invocation, then evaluate the log_each_individual_auth_fail setting, then fall through to the Redis EXISTS/SETEX 3600-second throttle, and finally record the key in the memo. The Redis-unavailable fallback (log everything) is preserved.
CVSS rationale
The vulnerable paths are reachable over the network (AV:N) with no authentication (PR:N) and no user interaction (UI:N). The attack complexity is low (AC:L): an attacker simply sends repeated HTTP requests to the MISP API without an API key or with a key of the wrong length. No attack target is required (AT:N). There is no impact on confidentiality (VC:N, SC:N) or integrity (VI:N, SI:N). The availability impact is high (VA:H) because unbounded log writes can exhaust database storage, degrade query performance, and ultimately make the MISP instance unavailable. No secondary availability impact (SA:N) is evident from the patch.
Weakness rationale
- CWE-770 Two authentication-failure log write paths lacked any rate-limiting or throttling mechanism, allowing an unauthenticated remote attacker to generate an unbounded number of database log entries and exhaust storage or I/O resources. The fix adds the missing hourly per-key throttle.
- CWE-400 The unthrottled log writes constitute uncontrolled consumption of database write capacity and disk storage, enabling a denial-of-service condition. CWE-770 is the more specific primary weakness; CWE-400 captures the broader resource-exhaustion impact.
Assumptions to verify
- The tag_version_boundary (v2.5.46, 188 commits after fix) is used as an approximate upper bound for affected versions; the exact fixed release tag is not stated in the patch metadata.
- The log entries are written to a relational database (MySQL/PostgreSQL) via MISP's Log model, based on the createLogEntry() call pattern; the specific backend is not confirmed in the patch.
- The Redis instance used for throttling is assumed to be co-located with the MISP application; a Redis outage degrades to logging everything (fail-open), which is a design choice documented in the patch comments.
- CVSS VA:H assumes that sustained unthrottled log writes can exhaust storage or I/O capacity sufficient to degrade or halt the MISP service; actual impact depends on deployment sizing and disk capacity.

"The log entries are written to a relational database (MySQL/PostgreSQL) via MISP\u0027s Log model, based on the createLogEntry() call pattern; the specific backend is not confirmed in the patch.",
"The Redis instance used for throttling is assumed to be co-located with the MISP application; a Redis outage degrades to logging everything (fail-open), which is a design choice documented in the patch comments.",
"CVSS VA:H assumes that sustained unthrottled log writes can exhaust storage or I/O capacity sufficient to degrade or halt the MISP service; actual impact depends on deployment sizing and disk capacity."

"cvssRationale": "The vulnerable paths are reachable over the network (AV:N) with no authentication (PR:N) and no user interaction (UI:N). The attack complexity is low (AC:L): an attacker simply sends repeated HTTP requests to the MISP API without an API key or with a key of the wrong length. No attack target is required (AT:N). There is no impact on confidentiality (VC:N, SC:N) or integrity (VI:N, SI:N). The availability impact is high (VA:H) because unbounded log writes can exhaust database storage, degrade query performance, and ultimately make the MISP instance unavailable. No secondary availability impact (SA:N) is evident from the patch.",

"fixSummary": "The fix applies the existing hourly per-key log throttle to the two previously unguarded authentication-failure log writes. The throttle key is now derived from the client\u0027s source IP address rather than from caller-supplied input, preventing an attacker from generating unbounded Redis throttle entries. A per-request memo (stored in Configure::read(\u0027CurrentRequestAuthFailKeys\u0027)) is added to _shouldLog() to prevent duplicate log entries when beforeFilter() executes a second time via CakeErrorController on an exception, ensuring one request produces at most one log entry per key regardless of the operator\u0027s log_each_individual_auth_fail setting.",

Client-Side Denial of Service (DoS) through ''/splunkd/__raw/services/authentication/users/username'' REST API endpoint in Splunk Enterprise
Summary
In Splunk Enterprise versions below 10.2.0, 10.0.2, 9.4.8, 9.3.9, and 9.2.12, and Splunk Cloud Platform versions below 10.2.2510.3, 10.1.2507.8, 10.0.2503.9, and 9.3.2411.121, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious payload into the `realname`, `tz`, or `email` parameters of the `/splunkd/__raw/services/authentication/users/username` REST API endpoint when they change a password. This could potentially lead to a client‑side denial‑of‑service (DoS). The malicious payload might significantly slow page load times or render Splunk Web temporarily unresponsive.

Title
Pivotick - Stack Exhaustion Denial of Service via Deep or Cyclic Graph Data
Summary
Pivotick contains an uncontrolled-recursion vulnerability when processing caller-supplied graph and node data. The affected graph algorithms recursively traversed graph edges, while the JSON viewer recursively processed each level of a node’s data structure. A specially crafted graph containing an excessively long path, deeply nested properties, or circular object references could therefore exhaust the JavaScript call stack when Pivotick calculates a layout or displays a node in the inspection modal.
Successful exploitation may cause an uncaught exception, freeze the affected page, or crash the browser tab, resulting in a client-side denial of service. No confidentiality or integrity impact has been identified.
The patch replaces the recursive graph traversals with iterative stack-based implementations and limits the reachability calculation to 1,000,000 edge traversals. It also limits JSON rendering to 64 levels and detects circular references before descending further into an object.

Title
MISP Unauthenticated Mail Endpoints Allow Unbounded Storage Consumption and Request Flooding
Summary
Affected versions of MISP permit unauthenticated or weakly constrained request paths to perform persistent work without adequate input bounds or rate limiting.
The users/forgot password-reset endpoint accepted an attacker-controlled email value without first imposing a reasonable length bound or validating its format. That value was then used to create an audit log entry and queue a password-reset job, causing the supplied value to be persisted more than once per request. The commit explicitly states that an unbounded unauthenticated request field was stored twice per call with no throttle.
The fix adds:
- a maximum email input length of 1024 bytes;
- email-format validation before persistent work;
- a per-source pre-authentication request budget;
- HTTP 429 responses when that budget is exceeded;
- a 15-minute cooldown for API-access request emails;
- POST-only handling and CSRF protection for the API-access request endpoint.
The new flood filter is specifically intended to limit persistent storage costs from anonymous requests such as password resets, registrations, and failed REST authentication attempts.

Mitigation
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.
Mitigation
Architecture and Design
- Mitigation of resource exhaustion attacks requires that the target system either:
- The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
- The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
- recognizes the attack and denies that user further access for a given amount of time, or
- uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.
Mitigation
Implementation
Ensure that all failures in resource allocation place the system into a safe posture.
CAPEC-147: XML Ping of the Death
An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
CAPEC-227: Sustained Client Engagement
An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.
CAPEC-492: Regular Expression Exponential Blowup
An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
