CVE-2021-38927Network attack vector

Credential disclosure via embedded Web UI JavaScript

Published Dec 25, 2023 · Updated Aug 4, 2024

Stored cross-site scripting in IBM Aspera Console 3.4.0 allows remote attackers to execute JavaScript in the Web UI. The Web UI retains attacker-supplied JavaScript and renders it in a trusted session, but IBM has not disclosed the affected field or output path. A trusted session must process the embedded code, which can expose credentials and alter displayed functionality without interrupting the service.
