CVE-2021-20350Network attack vector

Credential disclosure via Web UI script injection

Published Mar 4, 2021 · Updated Sep 16, 2024

Cross-site scripting in IBM Engineering products 6.0.2 through 7.0.2 allows remote authenticated users to run JavaScript in the Web UI. IBM states that user-supplied content is embedded as arbitrary JavaScript, but does not identify the affected field or output-encoding failure. Exploitation requires low-privileged access and victim interaction, allowing script execution in a trusted session and credential disclosure.
