Discussion

snom VoIP Phone Web Interface HTTP Request Authentication Bypass Vulnerability

The web interface on snom VoIP phones is prone to an authentication-bypass vulnerability because it fails to properly verify HTTP requests.

Successful exploits may allow attackers to bypass security restrictions and reconfigure the phones or make arbitrary use of the phones.

snom VoIP phones with firmware prior to 6.5.20, 7.1.39 and 7.3.14 are vulnerable.
