CVE-2021-38946Network attack vector

Credential disclosure via stored Web UI scripts

Published Apr 22, 2022 · Updated Sep 16, 2024

Cross-site scripting in IBM Cognos Analytics 11.1.7, 11.2.0, and 11.2.1 allows remote authenticated users to disclose credentials. The Web UI accepts embedded arbitrary JavaScript and later executes it within another user's trusted browser session rather than neutralizing it. A low-privileged account and user interaction are required, and the documented consequence is credential disclosure and alteration of Web UI behavior.
