A flaw was found in velocity. An attacker, able to modify Velocity templates, may execute arbitrary Java code or run arbitrary system commands with the same privileges as the account running the Servlet container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Apache WSS4J 1.6.5 contained a countermeasure for Bleichenbacher's attack on XML Encryption, where the PKCS#1 v1.5 Key Transport Algorithm is used to encrypt symmetric keys as part of WS-Security. In particular, the fix avoided leaking information on whether decryption failed when decrypting the encrypted key or decrypting the message data.

However, it is still possible to craft a message such that an attacker can tell where the decryption failure took place, and hence WSS4J is vulnerable to the original attack.

See here for more information on the original fix for WSS4J 1.6.5:

A flaw was found in JBoss web services where the services used a weak symmetric encryption protocol, PKCS#1 v1.5. An attacker could use this weakness in chosen-ciphertext attacks to recover the symmetric key and conduct further attacks.

Apache WSS4J as used by Apache CXF with the TransportBinding does not, by default, properly enforce all security requirements associcated with SAML SubjectConfirmation methods. Web service endpoints, secured by WSS4j, that rely on SAML for authentication are considered vulnerable to types of spoofing attacks.

Apache WSS4J before 1.6.17 and 2.x before 2.0.2 allows remote attackers to bypass the requireSignedEncryptedDataElements configuration via a vectors related to "wrapping attacks."
