CVE-2021-29804Network attack vector

Credential disclosure via stored Web UI script

Published Jul 12, 2021 · Updated Sep 16, 2024

Stored cross-site scripting in IBM Tivoli Netcool/OMNIbus WebGUI 8.1.x allows remote authenticated users to expose session credentials. The Web UI stores user-supplied JavaScript and later renders it in a trusted session without neutralization; IBM has not identified the affected field or handler. An authenticated user must first persist the script; execution in another trusted session can disclose credentials and alter displayed content.
