CVE-2020-4866Network attack vector

Credential disclosure via Web UI script injection

Published Mar 4, 2021 · Updated Sep 17, 2024

Cross-site scripting in three IBM Engineering products allows remote authenticated users to disclose credentials through the Web UI. IBM identifies only the Web UI and has not disclosed the input field or missing output-neutralization operation that accepts attacker-supplied JavaScript. A low-privileged user must submit the input and a victim must interact with it in a trusted session, where script execution can expose credentials.
