CVE-2023-40367Network attack vector

Credential disclosure via unneutralized Web UI script

Published Oct 14, 2023 · Updated Sep 16, 2024

Cross-site scripting in IBM QRadar SIEM 7.5.0 through 7.5.0 UP6 allows remote authenticated users to disclose credentials. The Web UI accepts user-supplied JavaScript and renders it without sufficient neutralization, causing execution in another user's trusted session. A valid low-privilege account and victim interaction are required; IBM has not identified the affected Web UI field or handler.
