Apache ActiveMQ < 5.19.3 / 5.19.4, 6.x < 6.2.2 / 6.2.3 Classpath Path Traversal

medium Nessus Plugin ID 305954

Synopsis

The remote host is running a web application that is affected by a path traversal vulnerability.

Description

The version of Apache ActiveMQ running on the remote host is prior to 5.19.3 / 5.19.4 or 6.x prior to 6.2.2 / 6.2.3.
It is, therefore, affected by an improper validation and restriction of classpath path name vulnerability:

 - An authenticated user could exploit path concatenation to traverse the classpath in two specific contexts: when creating a Stomp consumer and when browsing messages via the Web console. This vulnerability enables classpath path resource loading that could potentially be combined with other attacks for exploitation. (CVE-2026-33227)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache ActiveMQ version 5.19.3 / 5.19.4, 6.2.2 / 6.2.3, or later.
