Tenda AC18 fromSetWirelessRepeat function buffer overflow vulnerability

The Tenda AC18 is a router from the Chinese company Tenda. The Tenda AC18 suffers from a buffer overflow vulnerability that originates from the wpapsk_crypto5g parameter of the fromSetWirelessRepeat function failing to correctly validate the length of the input data, which can be exploited by a remote attacker to execute arbitrary code on the system or cause a denial of service attack.
