CVE-2023-43015Network attack vector

Credential disclosure via Web UI script injection

Published Dec 1, 2023 · Updated Nov 21, 2024

Cross-site scripting in IBM InfoSphere Information Server 11.7 allows remote authenticated users to inject JavaScript into the Web UI. IBM has not published the affected Web UI field, route, or missing neutralization operation, so the precise input-to-output path remains undisclosed. Exploitation requires low-privileged access and victim interaction; injected code runs within a trusted browser session and can alter displayed content or disclose credentials.
