## Overview

FreePBX is an open-source web-based graphical user interface. FreePBX 15, 16, and 17 endpoints are vulnerable due to insufficiently sanitized user-supplied data allowing unauthenticated access to FreePBX Administrator leading to arbitrary database manipulation and remote code execution. This issue has been patched in endpoint versions 15.0.66, 16.0.89, and 17.0.3.

## Affected

- `freepbx >= 15.0, < 15.0.66`
- `freepbx >= 16.0, < 16.0.89`
- `freepbx >= 17.0, < 17.0.3`

## Remediation

Upgrade past the affected range:

- `freepbx 17.0.3`
