PHP Version: OS:

 

 [2002-03-01 12:46 UTC] ghopper at cox dot net 
Windows NT 5.0 build 2195
Microsoft-IIS/5.0
php version 4.1.1 (the binary zip package for win32)
php is running cgi-mode (php.exe)

example script:

$arg = "junk && start cmd junk";
$arg = escapeshellarg($arg);
system("anycommand $arg",$output);

This starts a command shell running as the web server process.  This could be used as an exploit if the contents of $arg come from a form.

This also works with system(escapeshellcmd("anycommand $arg"));

As a suggestion, you might want to create a command to "removeshellchars" instead of just quoting them.
