Name of the Vulnerable Software and Affected Versions GateOne version 1.1

Description The issue allows arbitrary file download without authentication via "/downloads/.." directory traversal because os.path.join is misused. This can be exploited through the "/downloads/" API endpoint.

Recommendations For GateOne version 1.1, as a temporary workaround, consider restricting access to the "/downloads/" API endpoint until a patch is available. Avoid using the os.path.join function in a way that allows directory traversal until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
