A vulnerability, which was classified as critical, was found in TOTOLINK A702R 4.0.0-B20230721.1521. Affected is an unknown function of the file /boafrm/formFilter of the component HTTP POST Request Handler. The manipulation of the argument ip6addr leads to buffer overflow. It is possible to launch 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.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
