A vulnerability has been found in Tenda AC20 16.03.08.12. This affects the function set_qosMib_list of the file /goform/SetNetControlList of the component SetNetControlList Endpoint. The manipulation of the argument list leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
