Technical details

A classic buffer overflow vulnerability exists in the D-Link DIR-513 firmware version 1.10. The flaw is located within the 'formAdvanceSetup' function of the '/goform/formAdvanceSetup' endpoint, which serves as a POST request handler. By manipulating the 'webpage' argument, a remote attacker with low privileges can trigger a memory corruption. This can lead to arbitrary code execution or a complete system crash (DoS). Public exploit code is reportedly available. As the device is end-of-life (EOL), no patch is expected from the vendor.
