Description

This module exploits a vulnerable sudo configuration that permits the zimbra user to execute postfix as root. In turn, postfix can execute arbitrary shellscripts, which means it can execute a root shell.

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.
