| 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/formDiskPartition. The manipulation of device/partition name arguments leads to command injection in umount/parted commands. The attack is possible remotely after authentication.
In the formDiskPartition handler (0x46F610) partition device names are concatenated into umount /dev/%s%s and parted /dev/%s -s rm %s commands executed via system(). Device names come from the devicename parameter and partition table entries (written by the Add_Partition/Delete_Selected flows). |
