How the Exploit Works

The vulnerability results from improper sanitization of the ‘noticeId’ parameter in the /parameter/getLimitIPList.jsp file. An attacker can exploit this by injecting malicious SQL statements as the ‘noticeId’ parameter value. This could allow the attacker to manipulate the database, leading to unauthorized access, data leakage, or even system compromise.

Conceptual Example Code

Here’s a conceptual example of how an attacker might exploit this vulnerability.

GET /parameter/getLimitIPList.jsp?noticeId=1' OR '1'='1 HTTP/1.1
Host: target.example.com

In this example, the ‘noticeId’ parameter is manipulated with an SQL injection payload (`1′ OR ‘1’=’1`) that could potentially bypass authentication or reveal sensitive data.

Mitigation

As of this writing, the vendor has not responded to this disclosure, and no official patch has been released. As a temporary mitigation measure, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and filter out malicious SQL injection attempts. Users should also restrict access to the vulnerable application as much as possible until a patch is available.
