Draytek ≫ Vigor3910 Firmware

A stack-based Buffer Overflow vulnerability in DrayTek Vigor310 devices through 4.3.2.6 allows a remote attacker to execute arbitrary code via a long query string to the cgi-bin/ipfedr.cgi component.

Stored XSS, by authenticated users, is caused by poor sanitization of the Login Page Greeting message in DrayTek Vigor310 devices through 4.3.2.6.
