CVE-2021-29670Network attack vector

Credential disclosure via embedded Web UI JavaScript

Published Jun 2, 2021 · Updated Sep 16, 2024

Cross-site scripting in IBM Engineering web products 6.0.6 through 7.0.2 allows remote authenticated users to disclose credentials. The Web UI accepts user-supplied JavaScript and renders it as active content, but IBM has not disclosed the affected field, endpoint, or failed neutralization operation. Exploitation requires a low-privileged authenticated user to plant the script and another user to interact with the affected page, exposing credentials within that trusted session.
