Technical details
A cross-site request forgery (CSRF) vulnerability in airMAX M devices allows an unauthenticated attacker to perform arbitrary actions on behalf of an authenticated user. The attack requires social engineering to lure an authenticated user to a malicious page while they have an active session with the device's web interface. Successful exploitation enables unauthorized device configuration changes and denial-of-service attacks.
