| Title | D-Link Router D-Link DWR-M921 V1.1.52 Command Injection |
|---|
| Description | A vulnerability has been found in D-Link DWR-M921 firmware V1.1.52. It can be triggered through the route /boafrm/formDiskCreateShare. The manipulation of the argument folderpath leads to OS command injection. The attack is possible remotely after authentication.
In the formDiskCreateShare handler (0x470CB0) the folderpath parameter is concatenated into a mkdir command executed via system() (mkdir %s/"%s"); folderpath sits outside the quotes, so a semicolon injects directly. |
