  • Authentication bypass affects AMQP 0-8, 0-9, 0-91, and 0-10 connection handling in Apache Qpid Java before 6.0.3; monitor for unauthenticated or anomalous connections on AMQP ports using these protocol versions
  • Watch for unauthorized message injection or message theft on AMQP broker instances running Apache Qpid Java < 6.0.3, as exploitation allows injecting or stealing messages without valid credentials
  • The vulnerability is not exploitable if the ACL feature is enabled AND access to all virtual hosts is controlled; absence of 'ACCESS VIRTUALHOST' ACL clauses is an indicator of a vulnerable configuration
  • ·Mitigation (if upgrade is not possible): add 'ACCESS VIRTUALHOST' clauses to the ACL file to whitelist user access to all virtualhosts
  • ·Mitigation: if AMQP 0-8, 0-9, 0-91, and 0-10 are not required, disable these protocols at the Port level to eliminate the attack surface
  • ·Red Hat MRG 2/3 and Satellite 6 deployments of qpid-java are not affected because they use client certificate authentication rather than qpid-java's internal authentication system
