AlienVault OTX Malware

rabbitmq-server

RabbitMQ is a messaging and streaming broker. Prior to 4.1.11 and 4.2.6 on Windows, the RabbitMQ management plugin static file handler rabbit_mgmt_wm_static can pass URL-encoded backslashes to erl_prim_loader:read_file_info before path validation when multiple management extension plugins are enabled, causing outbound DNS and SMB requests to attacker-controlled UNC paths. This issue is fixed in versions 4.1.11 and 4.2.6.

RabbitMQ-server versions before 4.1.11 and 4.2.6 on Windows contain an absolute path traversal vulnerability in the management plugin's static file handler (rabbit_mgmt_wm_static). When multiple management extension plugins are enabled, the handler passes URL-encoded backslashes to erl_prim_loader:read_file_info without proper path validation. This flaw can cause the server to make outbound DNS and SMB requests to attacker-controlled UNC paths, potentially exposing sensitive information or enabling further attacks. The issue is resolved in versions 4.1.11 and 4.2.6.

CVE-2026-57211: CWE-36: Absolute Path Traversal 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.
