## 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.
