Hardcoded credentials in the Akuvox R50P VoIP phone 50.0.6.156 allow an attacker to get access to the device via telnet. The telnet service is running on port 2323; it cannot be turned off and the credentials cannot be changed.

A command injection (missing input validation) issue in the IP address field for the logging server in the configuration web interface on the Akuvox R50P VoIP phone with firmware 50.0.6.156 allows an authenticated remote attacker in the same network to trigger OS commands via shell metacharacters in a POST request.

Missing file and path validation in the ringtone upload function of the Akuvox R50P VoIP phone 50.0.6.156 allows an attacker to upload a manipulated ringtone file, with an executable payload (shell commands within the file) and trigger code execution.
