Security researchers at WPScan and Wordfence have identified seventeen plugins published Catch Plugins (a division of Catch Themes, LLC) that have vulnerabilities. These vulnerabilities are rated as high and can result in an attacker being able to change the plugin configurations.

Cross Site Request Forgery (CSRF)

A user authentication exploit (lacking a capability check) and a Cross Site Request Forgery (CSRF) vulnerability are affecting 17 plugins published by Catch Themes.

These vulnerabilities allow any logged-in user, even a subscriber, to perform changes that are usually reserved for WordPress users with the highest editing privileges, like the administrator of the website.

According to WordPress security plugin publisher WPScan:

“Multiple Plugins from the CatchThemes vendor do not perform capability and CSRF checks in the ctp_switch AJAX action, which could allow any authenticated users, such as Subscriber to change the plugin’s configurations.”

Wordfence Reports Vulnerability in Catch Demo Import WordPress Plugin

Wordfence published a notice about a critical vulnerability discovered in one of these plugins as well, the Catch Themes Demo Import (versions up to and including version 1.7).

The Catch Themes Demo Import WordPress plugin was found to have an Arbitrary File Upload Vulnerability.

It’s unclear how severe this specific vulnerability is. The vulnerability was rated by Wordfence as 9.1 on a scale of 1 – 10 and described as Critical. However, the vulnerability was listed on the US government National Vulnerability Database with a rating of 7.2 (High).

According to Wordfence:

“The Catch Themes Demo Import WordPress plugin is vulnerable to arbitrary file uploads via the import functionality found in the ~/inc/CatchThemesDemoImport.php file, in versions up to and including 1.7, due to insufficient file type validation”

Wordfence recommends upgrading to version 1.8, or newer.
