Solaris ypupdated Command Execution

Description

This exploit targets a weakness in the way the ypupdated RPC application uses the command shell when handling a MAP UPDATE request. Extra commands may be launched through this command shell, which runs as root on the remote host, by passing commands in the format '|'. Vulnerable systems include Solaris 2.7, 8, 9, and 10, when ypupdated is started with the '-i' command-line option.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
