FreePBX Endpoint Manager vulnerabilities

The Endpoint Manager module in FreePBX contains an authenticated arbitrary file upload vulnerability affecting the fwbrand parameter. This parameter allows an attacker to change the file path, potentially leading to webshell upload. Authentication with a known username is required.

The Endpoint Manager module in FreePBX contains authenticated SQL injection vulnerabilities affecting multiple parameters in the basestation, model, firmware, and custom extension configuration areas. Authentication with a known username is required.

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions prior to 16.0.96 and 17.0.1 through 17.0.9 have a weak default password. By default, this is a 6 digit numeric value which can be brute forced. (This is the app_password parameter). Depending on local configuration, this password could be the extension, voicemail, user manager, DPMA or EPM phone admin password. This issue is fixed in versions 16.0.96 and 17.0.10.

The FreePBX Endpoint Manager module includes a Network Scanning feature that provides web-based access to nmap functionality. In Endpoint Manager 16 before 16.0.92 and 17 before 17.0.6, insufficiently sanitized user-supplied input allows authenticated OS command execution as the asterisk user. Authentication with a known username is required.
