Summary

The W3C XML Encryption Standard, as used in the JBoss Web Services (JBossWS) component in JBoss Enterprise Portal Platform before 5.2.2 and other products, when using block ciphers in cipher-block chaining (CBC) mode, allows remote attackers to obtain plaintext data via a chosen-ciphertext attack on SOAP responses, aka "character encoding pattern attack."
