PHP-Update blog.php Variable Overwriting Arbitrary Code Execution

high Nessus Plugin ID 23927

Synopsis

The remote web server contains a PHP script that is affected by a data modification vulnerability.

Description

The remote host is running PHP-Update, a content management system written in PHP.

The version of PHP-Update installed on the remote host fails to sanitize user-supplied arguments to the 'blog.php' script before importing them into the global symbol table. By leveraging this flaw, an unauthenticated, remote attacker can gain control of the application and possibly execute arbitrary code on the remote host, subject to the permissions of the web server user id.

Solution

Unknown at this time.
