CVE-2021-20351Network attack vector

Credential disclosure via Web UI script injection

Published Mar 4, 2021 · Updated Sep 17, 2024

Cross-site scripting in IBM Engineering products allows remote authenticated users to disclose credentials through crafted Web UI content. IBM states that user-supplied JavaScript is embedded in the Web UI, but does not identify the affected field, endpoint, or encoding failure. A user account and victim interaction are required; script execution can alter trusted-session behavior and disclose credentials.
