How the Exploit Works
The WP Dispatcher Plugin for WordPress is vulnerable to a SQL injection attack due to insufficient escaping on a user-supplied parameter and lack of enough preparation on the existing SQL query. Specifically, the ‘id’ parameter is not properly sanitized before being used in a SQL query.
This vulnerability allows an authenticated attacker with Contributor-level access or above to append malicious SQL queries into already existing queries. The attacker can craft a SQL query that manipulates the existing SQL query to extract sensitive information from the database, leading to potential data leakage or even system compromise.
Conceptual Example Code
Here is a hypothetical example of how the vulnerability might be exploited:
POST /wp_dispatcher?id=1;DROP TABLE users; HTTP/1.1
Host: vulnerable.wordpress.com
Content-Type: application/x-www-form-urlencoded
user=admin&password=passwordIn this example, the attacker appends a malicious SQL command (`DROP TABLE users;`) to the ‘id’ parameter in the HTTP request. If the server processes this request, it could result in the deletion of the ‘users‘ table from the database, demonstrating the potential severity of this vulnerability.
How to Mitigate
Users are strongly advised to apply the vendor patch immediately upon availability. In the meantime, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation. Regularly updating all WordPress plugins and core files to their latest versions can significantly reduce the risk of such vulnerabilities.
