CVE-2021-39043Network attack vector

Credential disclosure via stored dashboard script injection

Published May 20, 2022 · Updated Sep 16, 2024

Stored 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 external content dashboard widget stores user-supplied JavaScript and renders it in the Web UI without neutralization. An authenticated user must add or modify the widget, and the script runs in another user's trusted session, limiting the reported impact to credential disclosure and interface alteration.
