Overview
A critical vulnerability has been identified in the GoZen Forms plugin for WordPress, with a CVSS Severity Score of 7.5. This vulnerability allows unauthenticated attackers to perform SQL Injection attacks via the ‘forms-id’ parameter of the emdedSc() function. This could potentially compromise the system and lead to data leakage. Web administrators using this plugin should apply the vendor patch immediately to mitigate the risk.

How the Exploit Works
The vulnerability lies in the emdedSc() function of the GoZen Forms plugin. The ‘forms-id’ parameter in this function does not adequately escape user-supplied input, and the SQL query lacks sufficient preparation. This allows unauthenticated attackers to append additional SQL queries that can extract sensitive data from the database or even modify it.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited using an HTTP POST request with a malicious payload:
POST /wp-admin/admin-ajax.php?action=gozen_forms_embed_sc HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
forms-id=1 UNION SELECT 1,username,password FROM wp_users WHERE ID=1 --In this example, the attacker sends a POST request to the vulnerable endpoint with a ‘forms-id’ parameter containing a malicious SQL injection payload. This would result in data extraction from the WordPress users table.
Mitigation Guidance
The vendor has released a patch to address this vulnerability. Users of the GoZen Forms plugin for WordPress should apply this patch immediately. As a temporary mitigation, users can also implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability.
