|---|
| विवरण | During a security review of the D-Link DWR-M960 (Hardware B1, Firmware V1.01.07), a buffer overflow vulnerability was discovered in the VPN Configuration endpoint /boafrm/formVpnConfigSetup. The vulnerability is located within the sub_4196C4 function. This function handles the setup and restart of VPN services (IPSec/PPTP/L2TP).
At the beginning of the function, the code retrieves the submit-url parameter. After performing validation checks (via sub_419398) and executing system commands to restart the WAN/VPN services, 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. |
