SquirrelMail developers report:
SquirrelMail 1.4.22 (and other versions before 20170427_0200-SVN)
allows post-authentication remote code execution via a sendmail.cf
file that is mishandled in a popen call. It's possible to exploit this
vulnerability to execute arbitrary shell commands on the remote
server.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
