CVE-2022-45766
📋 TL;DR
Global Facilities Management Software (GFMS) Version 3 contains hardcoded credentials that allow remote attackers to compromise electronic key box systems. This vulnerability enables attackers to access, modify, or disrupt key management operations. Organizations using GFMS Version 3 for physical security key management are affected.
💻 Affected Systems
- Global Facilities Management Software (GFMS)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain complete control over electronic key boxes, potentially unlocking physical access to secured facilities, stealing keys, or disabling key management systems entirely.
Likely Case
Unauthorized access to key management systems leading to unauthorized key issuance, access log manipulation, or denial of service for legitimate users.
If Mitigated
Limited impact with proper network segmentation and monitoring, though hardcoded credentials remain a persistent threat.
🎯 Exploit Status
Exploitation requires only knowledge of the hardcoded credentials, which are likely documented or easily discovered. No special tools or skills needed beyond basic network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
Contact Key Systems Management for updated software version. No official patch information is publicly available at this time.
🔧 Temporary Workarounds
Network Segmentation
allIsolate GFMS systems from untrusted networks and implement strict firewall rules
Credential Rotation
allIf possible, change any default or hardcoded credentials in the system configuration
🧯 If You Can't Patch
- Implement strict network access controls allowing only authorized IP addresses to connect to GFMS systems
- Deploy network monitoring and intrusion detection specifically for GFMS traffic patterns
🔍 How to Verify
Check if Vulnerable:
Check if running GFMS Version 3. Attempt authentication using known default/hardcoded credentials if available.Check Version:
Check GFMS application interface or configuration files for version informationVerify Fix Applied:
Verify software has been updated to a version beyond 3.0. Test that hardcoded credentials no longer work.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful login with default credentials
- Unusual access patterns to key management functions
Network Indicators:
- Unauthorized IP addresses accessing GFMS management ports
- Traffic patterns indicating credential guessing
