An authenticated local file inclusion vulnerability exists in Sangoma Switchvox SMB Edition 8.3 (104997). The play_file functionality accepts user-controlled input through the sound_path parameter and fails to properly validate file paths before accessing the underlying filesystem. By supplying absolute paths, an authenticated attacker can retrieve files outside the intended directory scope.
