| 标题 | D-Link DWR-M920 1.1.50 Code Injection and Buffer Overflow |
|---|
| 描述 | A vulnerability has been found in D-Link DWR-M920 V1.1.50、V1.1.70. This vulnerability can be triggered through the route **/boafrm/formUSSDSetup**. The manipulation of the argument **ussdValue** leads to command injection and Stack Buffer Overflow. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used.
The **sub_41CF20** function retrieves the **ussdValue** parameter from the user request. The parameter is passed to the sprintf function without any sanitization and length check, and the result is passed to the system function via sub_41CDBC, which may cause command injection and Stack Buffer Overflow. |
