Woody code snippets – Insert Header Footer Code, AdSense Ads <= 2.5.0 -Authenticated (Contributor+) Remote Code Execution

The Woody code snippets – Insert Header Footer Code, AdSense Ads plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.5.0 via the 'insert_php' shortcode. This is due to the plugin not restricting the usage of the functionality to high level authorized users. This makes it possible for authenticated attackers, with contributor-level access and above, to execute code on the server.

The insert-php (aka Woody ad snippets) plugin before 2.2.8 for WordPress allows authenticated XSS via the winp_item parameter.

admin/includes/class.import.snippet.php in the "Woody ad snippets" plugin before 2.2.5 for WordPress allows unauthenticated options import, as demonstrated by storing an XSS payload for remote code execution.

admin/includes/class.actions.snippet.php in the "Woody ad snippets" plugin through 2.2.5 for WordPress allows wp-admin/admin-post.php?action=close&post= deletion.
