Summary

FreePBX before versions 16.0.47 and 17.0.30 has a vulnerability in the Framework module that allows a crafted backup to restore the hidden AUTHTYPE setting with the value none. An authenticated user with backup-restore access can disable FreePBX authentication during restoration, bypassing the UI removal of AUTHTYPE=none.

Risk Assessment

Risk of disabling authentication in FreePBX, potentially leading to unauthorized access to the system and data.

Recommendation

Update FreePBX to versions 16.0.47 or 17.0.30, which include the fix.

Original NVD description (English source)

FreePBX is an open source IP PBX. Prior to 16.0.47 and 17.0.30, the FreePBX Framework module permits a crafted backup to restore the hidden AUTHTYPE setting with the value none through runRestore() in amp_conf/htdocs/admin/libraries/Builtin/Restore.php. An authenticated user with sufficient backup-restore access or write access to backup files can thereby disable FreePBX authentication during restoration, bypassing the user-interface removal of AUTHTYPE=none. This issue is fixed in versions 16.0.47 and 17.0.30.
