Description

Sipera VIPER Lab has reported a vulnerability in the Vonage Motorola VT 2142 phone adapters, which can be exploited by malicious people to conduct spoofing attacks.

The vulnerability is caused due to the SIP stack accepting SIP INVITE messages without checking the validity of the request. This can be exploited to impersonate the Call Server by sending specially crafted SIP INVITE messages with the IP address of the server and e.g. spoof the caller ID.

Solution
Filter out SIP INVITE messages
