介绍

# CVE-2025-57819

Overview of this vulnerability quoted from @jfinstrom [here](https://gist.github.com/jfinstrom/60011630ed586a79f5b9c78313e0d708#file-freepbx-vulnerability-aug-2026-md)
> - Around 2025-08-21 multiple FreePBX systems began showing errors and later confirmed compromises.
> - Vendor (Sangoma/FreePBX Security Team) published an advisory on 2025-08-26 urging administrators to restrict public access to the Administrator Control Panel and offering EDGE module fixes.
> - The vulnerability is associated with the commercial Endpoint Manager (Endpoint) and appears to be an unauthenticated privilege escalation/RCE that can be exploited when the Administrator UI is exposed to hostile networks.
> - The EDGE fix prevents new exploitation but does not clean already-compromised systems.

## How does this detection method work?

This template sends a request to the FreePBX admin panel, extracts the version, and flags it as vulnerable if it falls within the affected version ranges of the newly disclosed zero-day (16.0.0.0–16.0.88.19 or 17.0.0.0–17.0.2.31).
