Synopsis

FreeBPX 17.0.x < 17.0.23 Authentication Bypass

Description

According to its self-reported version number, the FreePBOX application running on the remote host is prior to 16.0.44 or 17.x prior to 17.0.23. It is, therefore, affected by an authentication bypass when providing an Authorization header with an arbitrary value, a session is associated with the target user regardless of valid credentials.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to FreeBPX version 17.0.23 or later.
