CVE-2023-40704
📋 TL;DR
This vulnerability in Philips PACS systems allows attackers to gain unauthorized access by exploiting weak default passwords. It affects healthcare organizations using vulnerable Philips Picture Archiving and Communication System installations. Compromise could lead to database access, system disruption, and patient data integrity issues.
💻 Affected Systems
- Philips Picture Archiving and Communication System (PACS)
📦 What is this software?
Vue Pacs by Philips
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing database manipulation, patient data theft/modification, and denial of service to critical medical imaging systems.
Likely Case
Unauthorized access to sensitive patient data and potential system availability issues if passwords are discovered through brute force or credential leaks.
If Mitigated
Minimal impact with strong password policies, regular credential rotation, and proper network segmentation in place.
🎯 Exploit Status
Exploitation requires knowledge of default credentials but is trivial once obtained. No authentication bypass needed if default passwords are unchanged.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: N/A
Vendor Advisory: http://www.philips.com/productsecurity
Restart Required: No
Instructions:
1. Change all default passwords to strong, unique credentials
2. Implement password policies requiring complexity and regular rotation
3. Review Philips security advisory for specific guidance
🔧 Temporary Workarounds
Password Policy Enforcement
allImplement and enforce strong password policies across all PACS system accounts
Network Segmentation
allIsolate PACS systems from general network access and implement strict firewall rules
🧯 If You Can't Patch
- Implement multi-factor authentication if supported
- Deploy network monitoring and intrusion detection specifically for PACS system access patterns
🔍 How to Verify
Check if Vulnerable:
Review system configuration to verify if default Philips installation passwords are still in use. Check password policies and complexity requirements.
Check Version:
Consult Philips documentation for version-specific commands; typically through system administration interface
Verify Fix Applied:
Confirm all default passwords have been changed to strong, unique credentials. Verify password policies are enforced.
📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts, successful logins from unusual locations/times, multiple login attempts with default credentials
Network Indicators:
- Unexpected database access patterns, unusual network traffic to/from PACS systems
