CVE-2025-0656Network attack vector

Credential disclosure via undisclosed Web UI script injection

Published Sep 1, 2025 · Updated Sep 2, 2025

Cross-site scripting in IBM Concert Software 1.0.0 through 1.1.0 allows remote attackers to disclose credentials through its Web UI. IBM states that unauthenticated input is embedded as arbitrary JavaScript in the Web UI, but does not identify the accepting endpoint, field, or rendering path. Execution requires interaction by a user in a trusted session; the injected script can alter displayed functionality and expose that user's credentials.
