CVE-2020-4162Network attack vector

Credential disclosure via Web UI script injection

Published Mar 10, 2020 · Updated Sep 16, 2024

Cross-site scripting in IBM InfoSphere Information Server 11.5 and 11.7 allows remote authenticated users to steal trusted-session credentials. The Web UI accepts user-supplied content containing arbitrary JavaScript and renders it in another trusted session without neutralizing the script. Low-privileged access is required to plant the payload, and a victim must interact with the affected UI; execution can disclose credentials and alter page behavior.
