Executive Summary

The vulnerability in the Plugin Organizer WordPress plugin before version 10.2.4 is due to the plugin not sanitizing and escaping a parameter before using it in a SQL statement. This flaw allows users with subscriber-level access to perform SQL injection attacks, which means they can manipulate the database queries executed by the plugin.

Detection Guidance

This vulnerability can be detected by attempting to reproduce the SQL injection using specially crafted requests. One method involves logging in as a subscriber and using curl commands to test for SQL injection by injecting a payload with a SLEEP function. For example, first log in and save authentication cookies with: curl -c cookies.txt -d "log=subscriber" -d "pwd=password" -d "wp-submit=Log+In" "http://your-site/wp-login.php". Then send an AJAX request with the injection payload: curl -b cookies.txt -d "action=PO_perform_plugin_search" -d "PO_plugin_path=a%' OR SLEEP(3) OR '1%'='1" "http://your-site/wp-admin/admin-ajax.php". If the server response is delayed (e.g., sleeps for 6 seconds), it confirms the SQL injection vulnerability. [1]

Mitigation Strategies

The immediate step to mitigate this vulnerability is to update the Plugin Organizer WordPress plugin to version 10.2.4 or later, where the issue has been fixed. Avoid using vulnerable versions prior to 10.2.4 to prevent exploitation. [1]
