CVE-2025-4556
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 web management interface of Okcat Parking Management Platform from ZONG YU has an Arbitrary File Upload vulnerability, allowing unauthenticated remote attackers to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.
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 · high confidenceOkcat Parking Management Platform from ZONG YU contains an arbitrary file upload vulnerability in its web management interface. Unauthenticated remote attackers can upload malicious files (web shells) to the server and execute them, achieving arbitrary code execution on the underlying system.

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.
-
Confirm Okcat Parking Management Platform is installedInspect running services or application directories for Okcat Parking or ZONG YU parking management software. Check web server configurations for parking management related virtual hosts or applications.Affected if The system is running Okcat Parking Management Platform from ZONG YU
-
Determine the installed versionCheck application version files, about pages, or administrative interfaces for the software version number. Compare against any available version information from the vendor.Affected if The installed version is unknown or falls within the affected version range for this vulnerability
-
Verify web management interface is exposedCheck network accessible services to confirm the Okcat web management interface is reachable via HTTP/HTTPS from network locations.Affected if The web management interface is accessible over the network without authentication restrictions
-
Identify file upload functionalityLocate the file upload feature in the web management interface by examining upload forms, endpoints, or API paths related to document/image/file uploads.Affected if File upload functionality exists and is accessible in the web interface
-
Check upload endpoint authenticationTest access to the file upload endpoint without providing credentials to determine if authentication is required. Inspect session handling and access control configurations.Affected if File upload endpoint accepts requests without requiring valid authentication credentials
-
Inspect upload directory configurationExamine web server and application configuration to determine where uploaded files are stored relative to the web root and whether script execution permissions are restricted in those directories.Affected if Uploaded files are stored within the web root and script execution is permitted in the upload directory
The system is affected if it runs Okcat Parking Management Platform with an upload feature accessible without authentication and stores uploads in a web-accessible location where script execution is allowed.

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 strict file upload validation including authentication requirements, file type whitelist validation, file content inspection, store uploads outside webroot, and disable script execution in upload directories.
