CVE-2021-39024Network attack vector

Credential disclosure via stored Web UI script injection

Published May 10, 2022 · Updated Sep 17, 2024

Stored cross-site scripting in IBM Guardium Data Encryption 4.0.0.0 and 5.0.0.0 allows remote authenticated users to disclose credentials. The Web UI accepts attacker-supplied JavaScript and renders it in a trusted session without sufficient neutralization; IBM has not identified the affected request or field. High privileges are required to plant the script, and another user must interact with the poisoned interface before session credentials can be exposed.
