CVE-2021-29833Network attack vector

Credential disclosure via stored Web UI scripts

Published Sep 23, 2021 · Updated Sep 16, 2024

Stored cross-site scripting in IBM Jazz for Service Management 1.1.3.10 allows remote authenticated users to disclose credentials. IBM states that the Web UI stores user-supplied JavaScript, but has not identified the affected field, request handler, or missing output-encoding operation. Low-privileged access is required to plant the script; credential disclosure occurs when the stored content executes in another trusted session.
