A security vulnerability has been detected in Tenda AC21 and AC23 16.03.08.16. Affected is the function GetParentControlInfo of the file /goform/GetParentControlInfo. Such manipulation of the argument mac leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed publicly and may be used.

A vulnerability was detected in Tenda AC1206 15.03.06.23. Affected is the function GetParentControlInfo of the file /goform/GetParentControlInfo. The manipulation of the argument mac results in stack-based buffer overflow. It is possible to launch the attack remotely. The exploit is now public and may be used.

An issue was discovered on Tenda AC7 devices with firmware through V15.03.06.44_CN(AC7), AC9 devices with firmware through V15.03.05.19(6318)_CN(AC9), and AC10 devices with firmware through V15.03.06.23_CN(AC10). A buffer overflow vulnerability exists in the router's web server (httpd). When processing the page parameters for a post request, the value is directly written with sprintf to a local variable placed on the stack, which overrides the return address of the function, a causing buffer overflow.
