CyberRota Analysis
AI-GeneratedThe publicKeySave AJAX endpoint in FreePBX versions 17.0.5.34 to 17.0.10 allows authenticated administrators to append SSH public keys to the system's authorized_keys file without proper restrictions, potentially granting persistent shell access to the asterisk user. This vulnerability can lead to arbitrary command execution, unauthorized access to sensitive data, and service disruptions. Organizations using affected versions of FreePBX should prioritize upgrading to version 17.0.11 to mitigate these risks.

Original NVD Description
FreePBX is an open source IP PBX. From 17.0.5.34 until 17.0.11, the publicKeySave AJAX endpoint in Backup.class.php accepts an authenticated administrator's SSH public key and appends it to /home/asterisk/.ssh/authorized_keys for the asterisk system user without reliably enforcing backup-only command and source restrictions. The key grants persistent shell access that can execute arbitrary commands, access FreePBX and call data, modify system files, and disrupt services. This issue is fixed in version 17.0.11.
