## Technical details

An OS command injection vulnerability exists in the boa web server's formWizard handler when processing the newPass parameter. An authenticated attacker can craft a specially malformed HTTP POST request to inject shell metacharacters into a system() call that concatenates the unsanitized newPass value with the "Mcli" mesh command. The vulnerability requires the router to be configured in mesh mode, but this can be done through the web portal by an authenticated user.
