WP Super Cache Plugin for WordPress Multiple Insecure PHP Code Inclusion Macros Remote Code Execution
high Nessus Plugin ID 66305

Synopsis
The remote web server contains a PHP script that is affected by a remote PHP code injection vulnerability.Description
The WP Super Cache Plugin for WordPress installed on the remote host is affected by a remote PHP code execution vulnerability due to a failure to properly sanitize user-supplied input. An unauthenticated, remote attacker can submit a comment to a WordPress blog containing arbitrary PHP code. The blog comments can contain dynamic content that is ignored by the WordPress core, but when the cached version of the page is loaded, the code left in the comment will execute. This allows the attacker to execute arbitrary code, subject to the privileges of the web server user id.This issue exists because of an incomplete fix for CVE-2013-2009.
Note that the plugin is reportedly also affected by a cross-site scripting vulnerability; however, Nessus has not tested for this issue.
Also note that this plugin will post comments to the site, and it is recommended that the comments are removed from within the WordPress admin panel.
Solution
Upgrade to version 1.3.2 or later.See Also
