Description
The OTRS Agent Frontend configuration endpoint can be accessed without authentication. This allows unauthenticated remote users to retrieve internal application configuration that is intended for use by the authenticated Agent Frontend. The exposed information may include configured frontend routes and their associated authorization groups, authentication configuration, enabled product features, third-party integration settings, and other implementation details.

The exposed configuration does not directly contain user credentials or provide unauthorized modification of the OTRS configuration. However, the disclosed information may assist an attacker in fingerprinting the affected OTRS installation and identifying enabled functionality or security-relevant configuration that could be used to prepare further attacks.

* 8.0.X
