Description
The LDAPLoginModule implementation in the Java Authentication and Authorization Service (JAAS) in Apache ActiveMQ 5.x before 5.10.1 allows wildcard operators in usernames, which allows remote attackers to obtain credentials via a brute force attack. NOTE: this identifier was SPLIT from CVE-2014-3612 per ADT2 due to different vulnerability types.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.activemq:activemq-broker. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.apache.activemq:activemq-broker to 5.10.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2015-6524 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2015-6524 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2015-6524. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
