CVE-2025-4557
📋 TL;DR
The ZONG YU Parking Management System has missing authentication on specific APIs, allowing unauthenticated remote attackers to operate critical system functions. This affects all deployments of the vulnerable software version, enabling attackers to open gates and restart systems without credentials.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could open all parking gates simultaneously, allowing unauthorized vehicle access, then restart the system to disrupt operations and potentially cause physical security breaches or traffic incidents.
Likely Case
Unauthorized individuals gain physical access to restricted parking areas by remotely opening gates, potentially leading to theft, vandalism, or unauthorized parking.
If Mitigated
With proper network segmentation and authentication controls, impact is limited to denial of service through system restarts if the system is internet-facing.
🎯 Exploit Status
Simple HTTP requests to undocumented APIs can trigger gate operations and system restarts without any authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not provided in references
Restart Required: Yes
Instructions:
1. Contact ZONG YU vendor for patch information 2. Apply any available updates 3. Restart the parking management system 4. Verify authentication is required for all APIs
🔧 Temporary Workarounds
Network Segmentation
allIsolate parking management system on separate VLAN with strict firewall rules
API Access Control
allImplement reverse proxy with authentication for all API endpoints
🧯 If You Can't Patch
- Disconnect system from internet and restrict to internal network only with strict access controls
- Implement physical security measures as backup for gate control functions
🔍 How to Verify
Check if Vulnerable:
Attempt to access system APIs without authentication - if gate control or restart functions are accessible, system is vulnerableCheck Version:
Check system web interface or contact vendor for version informationVerify Fix Applied:
Verify authentication is required for all API endpoints and unauthorized requests are rejected📡 Detection & Monitoring
Log Indicators:
- Unauthenticated API calls to gate control or system restart endpoints
- Multiple failed authentication attempts followed by successful gate operations
Network Indicators:
- HTTP requests to undocumented API endpoints without authentication headers
- Unusual traffic patterns to parking system from external IPs
SIEM Query:
source_ip NOT IN authorized_ips AND destination_port=80|443 AND (uri CONTAINS 'gate' OR uri CONTAINS 'restart') AND auth_header IS NULL
