CVE-2009-0506: n/a vulnerability

CVE-2009-0506: Unspecified vulnerability in IBM WebSphere Application Server (WAS) 5.1 and 6.0.2 before 6.0.2.33 on z/OS,...

Unspecified vulnerability in IBM WebSphere Application Server (WAS) 5.1 and 6.0.2 before 6.0.2.33 on z/OS, when CSIv2 Identity Assertion is enabled and Enterprise JavaBeans (EJB) interaction occurs between a WAS 6.1 instance and a WAS pre-6.1 instance, allows local users to have an unknown impact via vectors related to (1) use of the wrong subject and (2) multiple CBIND checks.

Security readout for executives and security teams

This is a legacy IBM WebSphere Application Server issue on z/OS involving identity handling between mixed WebSphere versions. In a narrow configuration, a local user could trigger an unspecified impact when EJB interactions occur between WebSphere 6.1 and older instances. The public record does not define the impact severity. Exposure is most likely limited to legacy z/OS WebSphere estates running WAS 5.1 or vulnerable 6.0.2 levels with CSIv2 Identity Assertion enabled and mixed-version EJB communication with WAS 6.1. Prioritize if the organization still runs legacy WebSphere on z/OS with mixed-version EJB traffic. If those systems are retired or isolated, immediate business urgency is lower, but unsupported legacy middleware remains an operational risk. Mitigation focus: Identify any z/OS WebSphere 5.1 or 6.0.2 deployments still in service.; Upgrade vulnerable WAS 6.0.2 deployments to 6.0.2.33 or later IBM guidance.; Review IBM PK71143 and related support documents for supported fixes..
