AlienVault OTX Vulnerabilities

AlienVault OTX Malware

rabbitmq-server

RabbitMQ is a messaging and streaming broker. Prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5, the rabbitmq_federation_management plugin renders the consumer_tag field on the Federation Status page without HTML escaping, allowing a user who can configure a federation upstream or policy to execute JavaScript in the browser of a user viewing that page. This issue is fixed in versions 3.13.14, 4.0.19, 4.1.10, and 4.2.5.

The vulnerability in rabbitmq-server's federation management plugin involves improper neutralization of input during web page generation (CWE-79). Specifically, the consumer_tag field is rendered without HTML escaping on the Federation Status page, enabling stored cross-site scripting attacks. An attacker who can configure federation upstreams or policies can inject malicious scripts that execute in the context of users viewing the page. The flaw affects versions prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5 and has been addressed in these fixed releases.

CVE-2026-57213: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in rabbitmq rabbitmq-server

This update includes the following RPMs:

rabbitmq-server4.3:
  * rabbitmq-server4.3-4.3.2-1.hum1 (aarch64, x86_64)
  * rabbitmq-server4.3-4.3.2-1.hum1.src (src)

This Red Hat security advisory covers an update to Red Hat Hardened Images RPMs, including rabbitmq-server4.2 version 4.2.8-1.hum1 for aarch64 and x86_64 architectures. The update addresses multiple CVEs including CVE-2026-57211. A key vulnerability detailed is a Cross-site Scripting (XSS) flaw in RabbitMQ's management UI, where improper handling of the x-internal-purpose argument allows users with queue or exchange declaration permissions to inject and execute arbitrary JavaScript code in other users' browsers. This can lead to unauthorized code execution and potential confidentiality and integrity impacts. The advisory references multiple CVEs and CWE weaknesses related to input validation and access control. The update is part of a bug fix and enhancement release for Red Hat Hardened Images. The advisory provides links to Red Hat's update repositories and security contact information but does not explicitly confirm the patch status for each CVE. No known exploits in the wild have been reported for these vulnerabilities.
