CVE-2012-4446

Impact:
Moderate
Public Date:

Bugzilla:
851355: CVE-2012-4446 qpid-cpp: qpid authentication bypass
It was found that the Apache Qpid daemon (qpidd) treated AMQP connections with the federation_tag attribute set as a broker-to-broker connection, rather than a client-to-server connection. This resulted in the source user ID of messages not being checked. A client that can establish an AMQP connection with the broker could use this flaw to bypass intended authentication. For Condor users, if condor-aviary is installed, this flaw could be used to submit jobs that would run as any user (except root, as Condor does not run jobs as root).
