RCBlog index.php post Parameter Traversal Arbitrary File Access

medium Nessus Plugin ID 20825

Synopsis

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.

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

Solution

Remove the application as its author no longer supports it.
