How the Exploit Works
The vulnerability arises due to flawed authentication mechanisms in the APIs provided by ZONG YU’s Parking Management System. As such, an unauthenticated attacker can remotely access these APIs to perform operations such as opening gates or rebooting the system. The absence of proper authentication controls allows potential threat actors to bypass system security, thus gaining unauthorized access to system operations.
Conceptual Example Code
An example of exploiting this vulnerability might look like this:
POST /api/open_gate HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "gate_id": "1" }In this example, the attacker sends a POST request to the `/api/open_gate` endpoint, specifying a `gate_id` to open. Since the system does not require authentication for this API, the request is processed, and the gate opens.
Mitigation Guidance
There are two ways to mitigate this vulnerability. The first and most recommended is to apply the vendor patch. ZONG YU has released a patch that fixes the authentication issues in its APIs. All affected organizations should apply this patch as soon as possible.
If applying the patch is not immediately possible, organizations can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation. These systems can detect and block malicious requests to the vulnerable APIs, providing some protection until the patch can be applied.
Conclusion
CVE-2025-4557 represents a serious security risk to any organization using ZONG YU’s Parking Management System. Immediate action is required to prevent potential system compromise or data leakage. By understanding the nature of this vulnerability and taking the appropriate steps to mitigate it, organizations can protect their systems and data from unauthorized access.
