Overview
A newly identified vulnerability, CVE-2025-4556, is currently wreaking havoc in the cyber world. This vulnerability targets the web management interface of the Okcat Parking Management Platform developed by ZONG YU. The issue at hand is an Arbitrary File Upload vulnerability, allowing unauthenticated remote attackers to upload and execute web shell backdoors. As a result, these attackers can execute arbitrary code on the server, which has far-reaching implications for the security and integrity of the data stored there. Any organization using this platform is at risk, making this a wide-scale problem that needs immediate attention.

How the Exploit Works
The exploit takes advantage of the Arbitrary File Upload vulnerability in the Okcat Parking Management Platform’s web management interface. This vulnerability allows an attacker to upload and execute a web shell backdoor without requiring any authentication. The attacker can then use this backdoor to execute arbitrary code on the server, potentially gaining control over the entire system and possibly leading to data leakage.
Conceptual Example Code
Given below is a conceptual example of how the vulnerability might be exploited. Note that this is a simplified representation meant for illustrative purposes only.
POST /upload_endpoint HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="backdoor.php"
Content-Type: application/x-php
<?php
// malicious backdoor code here
?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--In the above example, an HTTP POST request is made to the ‘/upload_endpoint’ of the target server, which is vulnerable to the exploit. A malicious PHP file ‘backdoor.php’ is uploaded, which can be used by the attacker to execute arbitrary code on the server.
