class Metasploit3  'PHP CGI Argument Injection',
	  'Description'	=> %q{
		When run as a CGI, PHP up to version 5.3.12 and 5.4.2 is vulnerable to
		an argument injection vulnerability.  This module takes advantage of
		the -d flag to set php.ini directives to achieve code execution.
		From the advisory: "if there is NO unescaped '=' in the query string,
		the string is split on '+' (encoded space) characters, urldecoded,
		passed to a function that escapes shell metacharacters (the "encoded in
		a system-defined manner" from the RFC) and then passes them to the CGI
		binary."
