Ctek SkyRouter 4200 and 4300 Series Routers Remote Arbitrary Command Execution Vulnerability

Summary
Ctek SkyRouter 4200 and 4300 series routers are prone to a remote arbitrary command-execution vulnerability because it fails to adequately sanitize user-supplied input. Remote attackers can exploit this issue to execute arbitrary shell commands with superuser privileges, which may facilitate a complete compromise of the affected device.
