Stored cross-site scripting in IBM Security Guardium 11.5 allows remote authenticated users to disclose credentials through its Web UI. The Web UI stores privileged-user-supplied JavaScript without neutralizing it before execution in a trusted session. Privileged application access is required to plant the payload, whose execution allows credential disclosure and changes interface behavior.
