Security readout for executives and security teams
CVE-2011-4905 is a denial-of-service issue in Apache ActiveMQ before 5.6.0. A remote attacker could overload broker file descriptors using many OpenWire failover TCP connection requests, causing the broker to crash or hang. The business risk is interruption to message-driven systems, not data theft or code execution based on the provided sources. Exposure is most likely where legacy ActiveMQ brokers earlier than 5.6.0 accept OpenWire TCP connections from untrusted or broad networks. Internal-only brokers still matter if critical applications depend on queue availability. Treat as a service-availability risk for any legacy ActiveMQ environment. Prioritize remediation where messaging outages would affect customer-facing systems, order processing, security workflows, or operational automation. Mitigation focus: Upgrade affected Apache ActiveMQ deployments to 5.6.0 or later.; Check Apache ActiveMQ vendor guidance and AMQ-3294 for authoritative fix context.; Restrict broker TCP access to trusted application networks where possible..
