How the Exploit Works

CVE-2025-44073 is a SQL Injection vulnerability. It resides in the admin_comment_news.php component of SeaCMS v13.3. An attacker can exploit the application by sending specially crafted SQL queries to this component, which lacks proper sanitization of user-supplied input. This can allow an attacker to view, modify, or delete data in the backend database, potentially compromising the system and leading to data leakage.

Conceptual Example Code

Here’s a conceptual example of how this vulnerability might be exploited. This is a sample HTTP request that sends malicious SQL payload to the vulnerable component.

POST /admin_comment_news.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
param1=value1&param2=value2&param3=malicious_payload'

In this conceptual example, `malicious_payload’` would be a crafted SQL statement designed to manipulate the database, bypass security measures, or exfiltrate data.

Recommended Mitigation

Users are strongly recommended to apply the vendor patch as soon as it’s available to mitigate this vulnerability. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. These systems can detect and prevent SQL Injection attacks by identifying suspicious patterns in the HTTP requests and responses. However, these are not foolproof solutions and are only recommended until the official patch has been applied.
In conclusion, users of SeaCMS v13.3 are urged to take immediate action to secure their systems against CVE-2025-44073. By understanding the nature of the vulnerability and applying appropriate mitigations, potential system compromises or data leakages can be prevented.
