OpenMQ Config Parsing Flaw Allows Arbitrary File Read, RCE

Publication date: 2026-03-05

Last updated on: 2026-08-05

Assigner: Eclipse Foundation

Description
An unsafe parsing of OpenMQ's configuration in OpenMQ versions <6.5.2 and <6.9.0, allows a remote attacker to read arbitrary files from a MQ Broker's server. A full exploitation could read unauthorized files of the OpenMQ’s host OS. In some scenarios RCE could be achieved. This is fixed in OpenMQ 6.5.2, 6.9.0, and in GlassFish 7.0.26, 7.1.1, and 8.0.2.

CWE ID Description
CWE-22 The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
CWE-27 The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize multiple internal "../" sequences that can resolve to a location that is outside of that directory.

Executive Summary

[{'type': 'paragraph', 'content': "CVE-2026-24457 is a critical vulnerability in Eclipse OpenMQ, specifically in versions 6.5.1 and earlier, including OpenMQ implementations within Glassfish and Payara. It arises from unsafe parsing of OpenMQ's configuration files, which allows a remote attacker to read arbitrary files on the MQ Broker's host server."}, {'type': 'paragraph', 'content': 'This means an attacker can access unauthorized files on the host operating system where OpenMQ is running. In some cases, this vulnerability can also lead to remote code execution (RCE), allowing the attacker to run malicious code on the server.'}, {'type': 'paragraph', 'content': 'The vulnerability is related to path traversal and improper validation issues, classified under CWE-22 and CWE-27.'}] [1]

Impact Analysis

This vulnerability can have severe impacts including unauthorized disclosure of sensitive files on the server hosting OpenMQ. Attackers can read arbitrary files, potentially exposing confidential data.

In more severe scenarios, attackers may exploit this vulnerability to achieve remote code execution (RCE), which could allow them to take control of the affected server, disrupt services, or further compromise the network.

Given the critical CVSS score of 9.1, the risk posed by this vulnerability is high and could lead to significant security breaches.
