Summary

Qihoo 360 D603-2, D600-2, D606-6 and D706 devices running firmware 6.4.0 to 6.4.9 are affected. The testspeed_command function in /fs2/bin/iscm does not neutralize the host argument, so a remote attacker can inject operating system commands (CWE-78). The attack needs no privileges or user interaction. A public exploit has been released.
