Technical details
A server-side request forgery (SSRF) vulnerability exists in IBM WebSphere Application Server (traditional and Liberty) within the SIP container component. The flaw is triggered when the 'sipServlet-1.1' feature is enabled and is associated with missing authentication for critical functions (CWE-306). A remote, unauthenticated attacker can exploit this over the network to send crafted requests, potentially gaining access to internal resources or sensitive information. IBM has released interim fixes (APAR PH72053 and DT495928) and plans to include permanent fixes in upcoming fix packs (9.0.5.29, 8.5.5.31, and 26.0.0.9).
