CVE-2016-4432 qpid-java: Authentication bypass
Last modified: 2016-06-24 12:49:28 EDT
The code responsible for handling incoming AMQP 0-8, 0-9, 0-91, and 0-10 connections contains a flaw that allows authentication to be bypassed. An remote attacker can exploit this vulnerability to perform actions, without the need to specify valid credentials. For instance, unauthorised messages could be injected or messages stolen. The vulnerability cannot be exploited if the Access Control List (ACL) feature is enabled AND access to all virtual hosts controlled. Mitigation: If upgrading is not possible, the vulnerability can be mitigated using an ACL file containing "ACCESS VIRTUALHOST" clauses that white-lists user access to all virtualhosts. If AMQP 0-8, 0-9, 0-91, and 0-10 support is not required, the vulnerability can also be mitigated by turning off these protocols at the Port level.

Satellite 6 uses client certificates to authenticate clients and does not rely upon qpid-java'[s internal authentication system.
Statement: This issue did not affect the versions of the qpid -java broker as shipped with Red Hat MRG 2 and 3 and Satellite 6 as they did not use the access feature (e.g. Satellite 6 relies on client certificate authentication to control access).
