GHSA-Q447-RJ3R-2CGH

Vulnerability from github – Published: 2026-02-18 00:53 – Updated: 2026-03-05 21:53
VLAI
Summary
OpenClaw affected by denial of service via unbounded webhook request body buffering
Details

Summary

Multiple webhook handlers accepted and buffered request bodies without a strict unified byte/time limit. A remote unauthenticated attacker could send oversized payloads and cause memory pressure, degrading availability.

Details

Affected packages: - openclaw (npm): <2026.2.12 - clawdbot (npm): <=2026.1.24-3

Root cause: - Webhook code paths buffered request payloads without consistent maxBytes + timeoutMs enforcement. - Some SDK-backed handlers parse request bodies internally and needed stream-level guards.

Attack shape: - Send very large JSON payloads or slow/incomplete uploads to webhook endpoints. - Observe elevated memory usage and request handler pressure.

Impact

Remote unauthenticated availability impact (DoS) via request body amplification/memory pressure.

Patch details (implemented)

  • Added shared bounded request-body helper in src/infra/http-body.ts.
  • Exported helper in src/plugin-sdk/index.ts for extension reuse.
  • Migrated webhook body readers to shared helper for:
  • LINE
  • Nextcloud Talk
  • Google Chat
  • Zalo
  • BlueBubbles
  • Nostr profile HTTP
  • Voice-call
  • Gateway hooks
  • Added stream guards for SDK handlers that parse request bodies internally:
  • Slack
  • Telegram
  • Feishu
  • Added explicit Express JSON body limit handling for MS Teams webhook path.
  • Standardized failure responses:
  • 413 Payload Too Large
  • 408 Request Timeout

Tests

  • Added regression tests:
  • src/infra/http-body.test.ts
  • src/line/monitor.read-body.test.ts
  • extensions/nextcloud-talk/src/monitor.read-body.test.ts
  • Focused webhook/security test suite passes for patched paths.

Remediation

Upgrade to the first release containing this patch.

Vulnerability from github – Published: 2025-11-15 00:30 – Updated: 2025-11-15 00:30
VLAI
Details

Positive Technologies MaxPatrol 8 and XSpider contain a remote denial-of-service vulnerability in the client communication service on TCP port 2002. The service generates a new session identifier for each incoming connection without adequately limiting concurrent requests. An unauthenticated remote attacker can repeatedly issue HTTPS requests to the service, causing excessive allocation of session identifiers. Under load, session identifier collisions may occur, forcing active client sessions to disconnect and resulting in service disruption.

Vulnerability from github – Published: 2022-05-13 01:36 – Updated: 2022-05-13 01:36
VLAI
Details

A sustained sequence of different types of normal transit traffic can trigger a high CPU consumption denial of service condition in the Junos OS register and schedule software interrupt handler subsystem when a specific command is issued to the device. This affects one or more threads and conversely one or more running processes running on the system. Once this occurs, the high CPU event(s) affects either or both the forwarding and control plane. As a result of this condition the device can become inaccessible in either or both the control and forwarding plane and stops forwarding traffic until the device is rebooted. The issue will reoccur after reboot upon receiving further transit traffic. Score: 5.7 MEDIUM (CVSS:3.0/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) For network designs utilizing layer 3 forwarding agents or other ARP through layer 3 technologies, the score is slightly higher. Score: 6.5 MEDIUM (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) If the following entry exists in the RE message logs then this may indicate the issue is present. This entry may or may not appear when this issue occurs. /kernel: Expensive timeout(9) function: Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D50; 12.3X48 versions prior to 12.3X48-D30; 12.3R versions prior to 12.3R12-S7; 14.1 versions prior to 14.1R8-S4, 14.1R9; 14.1X53 versions prior to 14.1X53-D30, 14.1X53-D34; 14.2 versions prior to 14.2R8; 15.1 versions prior to 15.1F6, 15.1R3; 15.1X49 versions prior to 15.1X49-D40; 15.1X53 versions prior to 15.1X53-D31, 15.1X53-D33, 15.1X53-D60.

Details

Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user with viewer-level access can submit a request containing an oversized input value to an analytics collections management endpoint. Kibana will consume excessive CPU and memory resources while processing the request. This results in Kibana becoming unavailable to all users until the service is manually recovered.

Summary
Withdrawn Advisory: Netty vulnerability included in redis lettuce
Details

Withdrawn Advisory

This advisory has been withdrawn because users of Lettuce may independently exclude vulnerable versions of Netty from their dependencies, and those users should not receive alerts for CVE-2024-47535. This link is maintained to preserve external references.

Original Description

Summary

Note: i'm reporting this in this way purely because it's private and i don't want to broadcast vulnerabilities.

An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crashes. This vulnerability is fixed in 4.1.115.

Summary
Pillow subject to DoS via SAMPLESPERPIXEL tag
Details

Pillow starting with 9.2.0 and prior to 9.3.0 allows denial of service via SAMPLESPERPIXEL. A large value in the SAMPLESPERPIXEL tag could lead to a memory and runtime DOS in TiffImagePlugin.py when setting up the context for image decoding. This issue has been patched in version 9.3.0.

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.
