Summary

A vulnerability in the Tenda N301 wireless router allows attackers to initiate a denial of service condition by sending a malformed request that sets the WAN MTU value to zero. This parameter is only restricted through the device's graphical user interface, thus enabling an exploit via command injection. If the attacker successfully triggers this exploit, it results in the router crashing, disrupting network access for legitimate users.
