Executive Summary

The BEAR – Bulk Editor and Products Manager Professional for WooCommerce plugin for WordPress has a Cross-Site Request Forgery (CSRF) vulnerability in all versions up to and including 1.1.5.

This vulnerability exists because the plugin's function woobe_delete_tax_term() lacks nonce validation, which is a security measure to verify that requests are legitimate.

As a result, an attacker can trick an authenticated site administrator or shop manager into performing an unwanted action, such as deleting WooCommerce taxonomy terms like categories or tags, by sending a forged request.

Detection Guidance

This vulnerability involves a Cross-Site Request Forgery (CSRF) in the BEAR – Bulk Editor and Products Manager Professional for WooCommerce plugin, specifically due to missing nonce validation in the woobe_delete_tax_term() function.

To detect this vulnerability on your system, you can check if the plugin version is up to and including 1.1.5, as these versions are affected.

For network detection, monitoring for suspicious HTTP requests that attempt to invoke the woobe_delete_tax_term() function without proper authentication or nonce tokens could help identify exploitation attempts.

Since the vulnerability requires tricking an administrator or shop manager into clicking a malicious link, reviewing web server logs for unusual POST requests to endpoints related to taxonomy term deletion may be useful.

Specific commands to assist detection might include:

• Using grep on web server logs to find requests containing 'woobe_delete_tax_term' or related parameters, e.g., `grep -i woobe_delete_tax_term /var/log/apache2/access.log`
• Checking the installed plugin version via WP-CLI: `wp plugin get bulk-editor-and-products-manager-professional-for-woocommerce --field=version`
• Monitoring HTTP traffic for suspicious POST requests without valid nonce tokens targeting taxonomy term deletion URLs.
