Executive brief
The Totolink A3002MU wireless router contains a command injection vulnerability in its web management interface that allows attackers to execute arbitrary commands on the device. An attacker can exploit this by sending a specially crafted request to the /boafrm/formWsc endpoint, potentially gaining full control of the router and compromising any networks or devices connected to it.
Technical details
A command injection vulnerability exists in the formWsc function of the /bin/boa web server where the localPin parameter is concatenated into a shell command without proper validation or escaping. An attacker can inject shell metacharacters through a POST request to /boafrm/formWsc to execute arbitrary commands with router privileges. The vulnerability requires network access to the router's management interface but no authentication.
