| 제목 | D-Link DWR-M960 V1.0.07 Stack-based Buffer Overflow |
|---|
| 설명 | During a security review of the D-Link DWR-M960 (Hardware B1, Firmware V1.01.07), a buffer overflow vulnerability was discovered in the DDNS (Dynamic DNS) configuration endpoint /boafrm/formDdns. The vulnerability is located within the sub_4648F0 function. This function retrieves the submit-url parameter from the incoming HTTP request. After processing the DDNS settings, the function uses strcpy to copy the content of submit-url into a global variable/buffer named wizard_htm. Due to the lack of proper bounds checking on the input length before the copy operation, a malicious actor can supply an oversized submit-url parameter to overwrite the destination buffer and adjacent memory. This allows for application crashes (DoS) and potentially arbitrary code execution. |
