Submit #754486: D-Link DWR-M960 V1.01.07 Stack-based Buffer Overflowinfo

TitleD-Link DWR-M960 V1.01.07 Stack-based Buffer Overflow
DescriptionDuring a security review of the D-Link DWR-M960 (Hardware B1, Firmware V1.01.07), a buffer overflow vulnerability was discovered in the Advanced Firewall configuration endpoint /boafrm/formFirewallAdv. The vulnerability is located within the sub_425FF8 function. This function processes firewall settings and retrieves the submit-url parameter from the incoming HTTP request. When the request indicates a "save and apply" action (via the save_apply parameter or specific internal state dword_4DDE34), the function executes a strcpy operation to copy the content of submit-url into a global variable/buffer named wizard_htm. The code fails to verify if the length of the input string exceeds the size of the destination buffer. A malicious actor can exploit this by supplying an oversized submit-url parameter, leading to a buffer overflow that can cause a Denial of Service (DoS) or potentially allow for Arbitrary Code Execution.
