The 'php4' shell interpreter is present in the /cgi-bin/ directory, which could lead to remote code execution by calling it with arbitrary arguments.
Interpreters that should not be in this directory include, but are not limited to, sh, csh, tcsh, bash, ksh, rksh, zsh, ash, php4, perl, tclsh, php, php3, php4, and php5.
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.
