CVE-2021-29809Network attack vector

Credential disclosure via stored Web UI JavaScript

Published Sep 20, 2021 · Updated Sep 16, 2024

Stored XSS in IBM Tivoli Netcool/OMNIbus Web GUI 8.1.0 allows remote authenticated users to execute JavaScript in trusted sessions. The Web UI stores attacker-supplied content and later renders it as executable JavaScript, but IBM has not disclosed the affected field, page, or handler. A low-privileged account can plant the payload over the network; execution in a trusted browser can expose credentials and alter displayed content.
