CVE-2025-4557
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe specific APIs of Parking Management System from ZONG YU has a Missing Authentication vulnerability, allowing unauthenticated remote attackers to access specific APIs and operate system functions. These functions include opening gates and restarting the system.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Parking Management System from ZONG YU contains specific APIs that lack authentication controls, allowing unauthenticated remote attackers to access these endpoints and execute privileged operations including opening parking gates and restarting the system. This is a critical authentication bypass vulnerability with physical security implications given the ability to control physical access points.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify ZONG YU Parking Management System installationLocate the parking management software on your server or endpoint by checking installed programs, services, or application directories. Look for processes or services named 'ZONG YU' or 'Parking Management' running on the system.Affected if The software from ZONG YU is installed and running on your network.
-
Determine the installed versionCheck the application's version information through its administrative interface, about page, or by examining installation directories for version files. Compare the discovered version against any release notes or vendor documentation for CVE-2025-4557.Affected if The installed version falls within the vulnerable range or no patch has been applied.
-
Identify and test vulnerable API endpointsLocate the API endpoints associated with gate control and system restart functionality. These are typically accessible via paths such as /api/gate/open, /api/gatecontrol, /api/system/restart, or similar URL patterns. Attempt to access these endpoints using HTTP requests without providing any authentication credentials.Affected if The API endpoints respond successfully without requiring authentication tokens, session cookies, or other credentials.
-
Verify network accessibility of the APIsDetermine if these parking management APIs are exposed to external networks or the internet by reviewing firewall rules, reverse proxy configurations, and networkACL settings. Use network scanning tools to confirm whether ports used by the parking management system are reachable from untrusted networks.Affected if The vulnerable APIs are accessible from outside the trusted internal network or from unauthorized IP addresses.
Your environment is affected if ZONG YU Parking Management System is running and its gate control or system restart APIs are accessible without authentication credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper authentication and authorization checks on all vulnerable APIs; restrict network access to these endpoints through firewall rules or network segmentation until a vendor patch is available.
