Tenda M3 formdelMasteraclist function stack overflow vulnerability

Tenda M3 is an access controller from Tenda, China. Tenda M3 v1.0.0.12 is vulnerable to a stack overflow vulnerability, which stems from the fact that the items parameter of the formSetAccessCodeInfo function does not check the length of the input data. An attacker could exploit this vulnerability to cause a denial of service attack.
