CVE-2025-4555
📋 TL;DR
The Okcat Parking Management Platform web management interface lacks authentication controls, allowing unauthenticated remote attackers to directly access administrative functions. This affects all systems running the vulnerable software, potentially compromising parking facility operations and sensitive data.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could remotely open gates, disrupt parking operations, view sensitive license plate and parking records, restart systems causing service disruption, and potentially gain further system access.
Likely Case
Unauthorized access to parking records and license plate data, unauthorized gate operations, and system disruption through restarts.
If Mitigated
Limited impact if system is isolated behind firewalls with strict network controls and authentication proxies.
🎯 Exploit Status
Direct HTTP requests to management endpoints without authentication required. Simple curl commands or web browser access can exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in references - contact vendor for patched version
Vendor Advisory: https://www.twcert.org.tw/en/cp-139-10109-25719-2.html
Restart Required: Yes
Instructions:
1. Contact ZONG YU vendor for patched version. 2. Backup configuration. 3. Apply vendor-provided patch/update. 4. Restart system. 5. Verify authentication is required for all management functions.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict access to management interface using firewall rules
iptables -A INPUT -p tcp --dport [management_port] -s [trusted_ips] -j ACCEPT
iptables -A INPUT -p tcp --dport [management_port] -j DROP
Reverse Proxy with Authentication
allPlace authentication proxy in front of management interface
🧯 If You Can't Patch
- Immediately isolate system from internet using firewall rules
- Implement network segmentation and restrict access to trusted IPs only
🔍 How to Verify
Check if Vulnerable:
Attempt to access management interface endpoints without authentication using curl: curl -v http://[system_ip]:[port]/management_endpointsCheck Version:
Check web interface or contact vendor - no standard command providedVerify Fix Applied:
Verify authentication is required for all management functions. Test with unauthenticated requests to confirm access is denied.📡 Detection & Monitoring
Log Indicators:
- Unauthenticated access to management endpoints
- Multiple failed authentication attempts followed by successful unauthenticated access
- Gate operations from unauthenticated IPs
Network Indicators:
- HTTP requests to management endpoints without authentication headers/cookies
- Traffic from unexpected sources to management ports
SIEM Query:
source_ip=* AND dest_port=[management_port] AND http_status=200 AND NOT (auth_token EXISTS OR cookie EXISTS)
