Description


Sandor Attila Gerendi has discovered a vulnerability in WordPress, which can potentially be exploited by malicious users to compromise a vulnerable system.

Input passed via the "cat" parameter to index.php is not properly sanitised in the "get_category_template()" function in wp-includes/theme.php before being used to include files in template-loader.php. This can be exploited to include arbitrary PHP files from local resources via directory traversal attacks.

Successful exploitation allows execution of arbitrary PHP code, but requires privileges to store PHP files on an affected system and that WordPress is installed on a Windows platform.

The vulnerability is confirmed in version 2.3.3.


Solution:
Update to version 2.5.1.
