A vulnerability was identified in Tenda AC20 16.03.08.12. This issue affects the function sub_46A2AC of the file /goform/setMacFilterCfg. The manipulation of the argument deviceList leads to stack-based buffer overflow. The attack may be initiated 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.
