| Title | D-Link DWR-M960 V1.01.07 Stack-based Buffer Overflow |
|---|
| Description | During a security review of the D-Link DWR-M960 (Hardware B1, Firmware V1.01.07), a buffer overflow vulnerability was discovered in the LTE configuration endpoint /boafrm/formLteSetup. The vulnerability is located within the sub_4237AC function. This function handles LTE interface settings. At the beginning of the function, it retrieves the submit-url parameter. If the configuration check (sub_422EDC) returns a specific success code (1) and the save_apply parameter is present, 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. |
