Summary
The vulnerability affects Qihoo 360 D603-2, D600-2, and D606-6 router firmware, specifically the timezone push handling component. Improper handling of the timezone input lets a remote attacker run arbitrary operating system commands on the device.
Read the original description
A vulnerability was determined in Qihoo 360 D603-2, D600-2 and D606-6 up to 6.3.2. This vulnerability affects the function on_push_message of the file /fs2/bin/iscm of the component Timezone Push Handler. Executing a manipulation of the argument tz can lead to os command injection. The attack may be launched remotely. The exploit has been publicly disclosed and may be utilized. Upgrading to version 6.4.0 is able to resolve this issue. Upgrading the affected component is advised. Firmware 6.4.0 gates the path with a new check_timezone_parameter validation (verified by VulDB vulnerability analysis team via disassembly).
