Credential disclosure via embedded Web UI JavaScript

Published Sep 23, 2022 · Updated May 22, 2025

Cross-site scripting in IBM InfoSphere Information Server 11.7 allows remote authenticated users to disclose credentials through the Web UI. The Web UI accepts embedded user-provided JavaScript without neutralizing it, causing the script to execute within a trusted session. Exploitation requires authenticated access and victim interaction; the bounded effects are credential disclosure and alteration of Web UI behavior.
