Critical Vulnerabilities in ZONG YU Parking Management Systems
ZONG YU, a provider of parking management solutions, has recently disclosed multiple severe security vulnerabilities affecting its Parking Management System and Okcat Parking Management Platform. These vulnerabilities were published on May 11, 2025, and pose serious risks including unauthorized system control, arbitrary code execution, and data exposure. Below is a detailed analysis of each vulnerability, their impact, and example attack scenarios.
CVE-2025-4557: Missing Authentication in Parking Management System APIs
Severity: High (CVSS 8.8)
Published: May 11, 2025
Affected Product: ZONG YU Parking Management System APIs
Vulnerability Details:
This vulnerability arises from missing authentication controls on specific APIs of the ZONG YU Parking Management System. Unauthenticated remote attackers can exploit this flaw to access critical system functions without any credentials. The exposed functions include the ability to remotely open parking gates and restart the entire parking system, effectively giving attackers full operational control over the parking infrastructure148.
Impact:
Unauthorized gate access, potentially allowing free entry or exit
Disruption of parking services by restarting systems remotely
Potential facilitation of physical security breaches
Sample Attack Scenario:
An attacker scans the network and discovers the vulnerable API endpoints of the parking system. Without any authentication, the attacker sends crafted API requests to open gates at will, allowing unauthorized vehicles to enter or exit the parking facility. The attacker could also send commands to restart the system, causing service outages and operational chaos.
Mitigation:
Immediate implementation of robust authentication mechanisms on all exposed APIs
Restrict API access to trusted networks or VPNs
Apply security patches provided by ZONG YU as soon as available8
CVE-2025-4556: Arbitrary File Upload in Okcat Parking Management Platform
Severity: Critical (CVSS 9.3)
Published: May 11, 2025
Affected Product: Okcat Parking Management Platform (Web Management Interface)
Vulnerability Details:
The Okcat Parking Management Platform’s web management interface suffers from an arbitrary file upload vulnerability. This allows unauthenticated remote attackers to upload malicious files, such as web shell backdoors, onto the server. Once uploaded, attackers can execute arbitrary code on the server, gaining full control over the system2.
Impact:
Complete server compromise through remote code execution
Deployment of persistent backdoors for ongoing access
Potential data theft, manipulation, or destruction
Sample Attack Scenario:
An attacker accesses the vulnerable file upload feature without authentication and uploads a web shell disguised as a legitimate file. Using the web shell, the attacker executes commands on the server, installs malware, and pivots deeper into the network, compromising other systems.
Mitigation:
Update the Okcat Parking Management Platform to the latest secure version
Implement strict file validation and sanitization on upload features
Monitor server logs for suspicious file upload activities and web shell executions2
CVE-2025-4555: Missing Authentication in Okcat Parking Management Platform
Severity: Critical (CVSS 9.3)
Published: May 11, 2025
Affected Product: Okcat Parking Management Platform (Web Management Interface)
Vulnerability Details:
Similar to CVE-2025-4557, this vulnerability involves missing authentication controls on the Okcat Parking Management Platform’s web interface. Unauthenticated attackers can directly access sensitive system functions such as opening gates, viewing license plates and parking records, and restarting the system3.
Impact:
Unauthorized physical access by opening gates remotely
Exposure of sensitive data including license plate numbers and parking records
Disruption of parking operations through system restarts
Sample Attack Scenario:
Without needing to log in, an attacker accesses the web interface and retrieves confidential parking data. The attacker then issues commands to open gates, allowing unauthorized vehicles to enter. The attacker can also restart the system to cause denial of service.
Mitigation:
Enforce strict authentication and authorization on all management interfaces
Limit access to trusted users and networks only
Apply vendor patches promptly to close authentication gaps3
