IBM WebSphere Application Server (WAS) 6.1 before 6.1.0.39 and 7.0 before 7.0.0.17 uses a weak WS-Security XML encryption algorithm, which makes it easier for remote attackers to obtain plaintext data from a (1) JAX-RPC or (2) JAX-WS Web Services request via unspecified vectors related to a "decryption attack."

Security readout for executives and security teams

CVE-2011-1209 affects older IBM WebSphere Application Server 6.1 and 7.0 releases. A weak WS-Security XML encryption algorithm could make protected web services request data recoverable as plaintext by a remote attacker. The source bundle does not provide CVSS, CWE, or detailed exploit conditions. Exposure is most likely where legacy IBM WebSphere 6.1 or 7.0 hosts process JAX-RPC or JAX-WS SOAP web services using WS-Security XML encryption, especially if reachable by untrusted networks. Prioritize remediation for any legacy WebSphere systems handling sensitive transactions or externally reachable SOAP services. The issue can affect confidentiality, but available public evidence does not confirm exploitation or quantify severity. Mitigation focus: Upgrade WAS 6.1 to 6.1.0.39 or later where applicable.; Upgrade WAS 7.0 to 7.0.0.17 or later where applicable.; Review IBM PM34841 and related support guidance before production changes..
