All,

I recently gave a presentation on locking-down Apache Tomcat[1] and I
briefly discussed the "sharp edges" present in Tomcat. Some of them
are unnecessarily sharp and may be actually unnecessary. I'm going to
make a few proposals to remove functions from Tomcat.

Proposal: Remove CGI Servlet

Justification:

The CGIServlet is another component, like server-side-includes, which
is a remote-code execution (RCE) vulnerability as a feature. It is
very easy to misconfigure. It is arguably not possible to secure it on
Windows[2]. There are better solutions if you want to run Perl,
Python, PHP, or whatever on your server in the form of the many fine
web-server products out there.
