A low impact privilege escalation flaw in the JBoss ESB component was found whereby the execution of a service with a different domain could, potentially, have resulted in the pipeline being run with different sets of credentials, (one set from the first domain if the request were still valid and a second set from the other domain if it had expired).

Apache CXF 2.5.x before 2.5.10, 2.6.x before CXF 2.6.7, and 2.7.x before CXF 2.7.4 does not verify that a specified cryptographic algorithm is allowed by the WS-SecurityPolicy AlgorithmSuite definition before decrypting, which allows remote attackers to force CXF to use weaker cryptographic algorithms than intended and makes it easier to decrypt communications, aka "XML Encryption backwards compatibility attack."
