Executive Summary

This vulnerability affects the FreePBX Endpoint Manager module when the authentication type is set to "webserver." It allows an attacker to bypass authentication by providing an Authorization header with any arbitrary value, which causes the system to associate a session with the target user without requiring valid credentials. This means unauthorized users can gain access to the system as if they were authenticated.

Impact Analysis

The vulnerability can allow unauthorized access to telephony endpoints managed by FreePBX Endpoint Manager. This could lead to unauthorized control or manipulation of telephony devices, potential interception or disruption of communications, and compromise of system integrity and confidentiality.

Mitigation Strategies

Upgrade FreePBX Endpoint Manager to version 16.0.44 or 17.0.23 or later, where the authentication bypass vulnerability has been fixed.
