CVE-2021-29668Network attack vector

Credential disclosure via embedded Web UI JavaScript

Published Jun 2, 2021 · Updated Sep 17, 2024

Cross-site scripting in affected IBM Engineering products allows remote authenticated users to run JavaScript in trusted Web UI sessions. IBM has not published the vulnerable field or the code path that stores and renders the attacker-supplied script. Exploitation requires a low-privileged user to embed the script and another user to view the affected interface, exposing credentials entered or stored in that trusted session.
