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.

Zero-day exploitation has been observed. Immediate patching is recommended

Active exploitation has been observed. Immediate patching is recommended

Active exploitation has been observed, immediate patching is recommended.

According to its self-reported version number, the FreePBOX application running on the remote host is prior to 15.0.66 or 16.x prior to 16.0.89 or 17.x prior to 17.0.3. It is, therefore, affected by an insufficiently sanitized user-supplied data allowing unauthenticated access to FreePBX Administrator leading to arbitrary database manipulation and remote code execution.

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