How the Exploit Works

This exploit works by sending a crafted payload to the `/system/user/findUserList` API of Xinguan v0.0.1-SNAPSHOT. Because of the insecure access control, the API does not correctly verify the user’s permissions, allowing the attacker to access sensitive information.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited:

POST /system/user/findUserList HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "..." }

In this example, the attacker sends a crafted payload to the vulnerable endpoint. The payload is designed to exploit the insecure access control, forcing the system to return sensitive data that the attacker should not have access to.
This is a serious vulnerability that could lead to a full system compromise and data leakage. It is highly recommended for users to apply the vendor’s patch as soon as it is available or implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure.
