⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to access payment processing systems, steal financial data, manipulate transactions, and potentially pivot to other connected systems.
Likely Case
Unauthorized access to payment processing functions, viewing of sensitive customer data, and potential financial fraud through transaction manipulation.
If Mitigated
Limited impact if proper network segmentation, monitoring, and access controls prevent credential usage even if discovered.
🎯 Exploit Status
Exploitation requires reverse engineering the executable to extract credentials, but once obtained, usage is straightforward.

🔍 How to Verify
Check if Vulnerable:
Check PAVO Pay version via administrative interface or configuration files. If version is earlier than 13.05.2025, system is vulnerable.Check Version:
Check PAVO Pay admin interface or configuration files for version information (vendor-specific command)Verify Fix Applied:
Confirm version is 13.05.2025 or later and test authentication with old credentials to ensure they no longer work.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful authentication with unusual credentials
- Authentication from unexpected IP addresses or locations
