How the Exploit Works
The vulnerability exists due to insufficient escaping of the ‘bsa_pro_id’ parameter and lack of adequate preparation on the existing SQL query. An unauthenticated attacker can append additional SQL queries into existing queries. By exploiting this vulnerability, an attacker can manipulate SQL queries to extract sensitive information from the database.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP GET request, where an attacker appends a malicious SQL query to the ‘bsa_pro_id’ parameter.
GET /wp-content/plugins/ads-pro/?bsa_pro_id=1' OR '1'='1'; -- HTTP/1.1
Host: target.example.comThe above request triggers the SQL injection vulnerability, potentially returning sensitive information from the database.
Mitigation Guidance
It is recommended to apply the vendor patch as soon as it is available. Until then, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation. Ensure that these security systems are configured correctly to detect and prevent SQL injection attacks.
