CVE-2021-39059Network attack vector

Credential disclosure via embedded Web UI scripts

Published May 11, 2022 · Updated Sep 16, 2024

XSS in IBM Jazz Team Server 6.0.6, 6.0.6.1, 7.0, 7.0.1, and 7.0.2 allows remote authenticated users to disclose credentials. The Web UI accepts user-supplied JavaScript as interface content and executes it in another user's trusted browser session instead of neutralizing the script. Low-privileged access and victim interaction are required; successful execution can expose credentials and alter displayed functionality.
