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.

Description

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.
