Ads Pro Plugin – Multi-Purpose WordPress Advertising Manager | Versions up to and including 4.88
How the Exploit Works
The exploit works by an attacker injecting arbitrary SQL code into the ‘a_id’ parameter. This parameter is not properly sanitized before being used in SQL queries, allowing an attacker to manipulate the queries performed by the plugin, and thus extract sensitive data from the database or perform other unauthorized database operations.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request:
GET /wp-content/plugins/ads-pro-plugin/ads.php?a_id=1 UNION SELECT 1,username,password FROM wp_users WHERE id=1 HTTP/1.1
Host: target.example.comThis request attempts to inject a UNION SELECT SQL query into the ‘a_id’ parameter. If successful, this would result in the username and password of the first user (typically the administrator) being returned in the response.
Mitigation Guidance
Users are advised to apply the vendor patch as soon as it’s available. In the meantime, they can protect their systems by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block SQL injection attempts.
