How the Exploit Works

CVE-2025-45615 is an access control vulnerability. An attacker can exploit this vulnerability by sending a specially crafted request to the /admin/ API endpoint of yaoqishan v0.0.1-SNAPSHOT. Due to the incorrect access control mechanism, the software fails to properly validate this request and grants the attacker Admin rights. This could potentially lead to unauthorized system access, manipulation of system data, or even a full system compromise.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. In this hypothetical HTTP request, an attacker sends a malicious payload to the /admin/ API endpoint:

POST /admin/ HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "admin_privileges": "true" }

In this example, the “admin_privileges”: “true” part of the request is the malicious payload. The server incorrectly validates this request, granting the attacker admin rights.

Mitigation Guidance

The best way to mitigate the risk of this vulnerability is to apply the vendor’s patch once it’s available. Until the patch is released, an effective temporary mitigation can be achieved by using a web application firewall (WAF) or intrusion detection system (IDS) to block or alert on any suspicious activity related to the admin API.
As always, it’s recommended to keep all systems and software up-to-date, regularly review system logs for any suspicious activity, and follow best cybersecurity practices to ensure the security of your systems.
