The BackWPup Plugin for WordPress contains a flaw that may allow a remote attacker to execute arbitrary commands or code. The issue is due to the wp_xml_export.php script not properly sanitizing user input supplied to the 'wpabs' parameter. This may allow an attacker to include a file from a third-party remote host that contains commands or code that will be executed by the vulnerable script with the same privileges as the web server.
