Full title: VyOS restricted-shell Escape / Privilege Escalation Exploit 
Category: remote exploits
Platform: unix
This Metasploit module exploits command injection vulnerabilities and an insecure default sudo configuration on VyOS versions 1.0.0 through 1.1.8 to execute arbitrary system commands as root. VyOS features a restricted-shell system shell intended for use by low privilege users with operator privileges. This module exploits a vulnerability in the telnet command to break out of the restricted shell, then uses sudo to exploit a command injection vulnerability in /opt/vyatta/bin/sudo-users/vyatta-show-lldp.pl to execute commands with root privileges. This module has been tested successfully on VyOS 1.1.8 amd64 and VyOS 1.0.0 i386.
