Lifecycle Timeline
7DescriptionCVE.org
The Fileserver web application in Apache ActiveMQ 5.x before 5.14.0 allows remote attackers to upload and execute arbitrary files via an HTTP PUT followed by an HTTP MOVE request.
AnalysisAI
Remote code execution in Apache ActiveMQ 5.x before 5.14.0 allows unauthenticated attackers to upload and execute arbitrary files on the message broker server by chaining HTTP PUT and MOVE requests against the Fileserver web application. This vulnerability is confirmed actively exploited (CISA KEV) with EPSS score of 94.29%, publicly available exploit code exists, and vendor-released patch is available in ActiveMQ 5.14.0.
Technical ContextAI
Apache ActiveMQ is an open-source message broker implementing JMS (Java Message Service) for enterprise messaging. The vulnerable Fileserver web application component provides file management capabilities over HTTP. The root cause is CWE-434 (Unrestricted Upload of File with Dangerous Type), where the application fails to properly validate file uploads and restrict execution permissions. The attack exploits HTTP PUT to write arbitrary files to the server filesystem, then uses HTTP MOVE to relocate them to executable locations like webapps directories, bypassing typical upload restrictions. The affected CPE cpe:2.3:a:apache:activemq:*:*:*:*:*:*:*:* confirms this impacts the core ActiveMQ product across all platforms prior to version 5.14.0.
RemediationAI
Upgrade immediately to Apache ActiveMQ 5.14.0 or later, which removes the vulnerable Fileserver web application functionality according to the vendor advisory at http://activemq.apache.org/security-advisories.data/CVE-2016-3088-announcement.txt and commit thread at https://lists.apache.org/thread.html/a859563f05fbe7c31916b3178c2697165bd9bbf5a65d1cf62aef27d2%40%3Ccommits.activemq.apache.org%3E. Red Hat customers should apply RHSA-2016-2036 for integrated products. If immediate upgrade is not feasible, disable the Fileserver web application by removing or commenting out the fileserver servlet mapping in the ActiveMQ web.xml configuration file, though this breaks legitimate file transfer functionality. Network segmentation to restrict ActiveMQ admin interface access to trusted management networks provides defense-in-depth but does not eliminate risk if attackers gain internal network access. Do not rely on authentication controls alone as the vulnerability affects unauthenticated endpoints. Given active exploitation and available weaponized exploits, workarounds should be considered temporary emergency measures only pending full upgrade.
