💻 Affected Systems
- Amano Xparc parking management software
📦 What is this software?
Xoffice by Amano
⚠️ Risk & Real-World Impact
Worst Case
Attackers could read sensitive system files, obtain credentials, and potentially achieve remote code execution by including executable files.
Likely Case
Unauthorized access to configuration files, logs, and potentially sensitive parking system data.
If Mitigated
Limited to reading non-critical files if proper file permissions and web server restrictions are in place.
🎯 Exploit Status
The vulnerability is publicly documented with proof-of-concept details available in the referenced Medium article.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.amano.eu/en/parking/xparc/
Restart Required: No
Instructions:
1. Check Amano website for security updates. 2. Contact Amano support for patch availability. 3. Apply any available updates following vendor instructions.
🔧 Temporary Workarounds
Web Server File Restriction
allConfigure web server to restrict file access to specific directories only
# For Apache: Set appropriate Directory and FilesMatch directives
# For IIS: Configure request filtering rules
Application Firewall Rules
allImplement WAF rules to block LFI patterns in requests
# Example ModSecurity rule: SecRule ARGS "\.\./" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Isolate the Xparc system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor for suspicious file access patterns
🔍 How to Verify
Check if Vulnerable:
Test for LFI by attempting to access known system files through the web interface using path traversal techniquesCheck Version:
Check Xparc web interface or application properties for version informationVerify Fix Applied:
Retest LFI attempts after applying mitigations to confirm they are blocked📡 Detection & Monitoring
