CVE-2024-7346
📋 TL;DR
This vulnerability allows attackers to bypass TLS host name validation when OpenEdge default certificates are used for network connections, enabling man-in-the-middle attacks. It affects OpenEdge installations using default TLS certificates for network security. Organizations relying on TLS certificate validation for secure communications are impacted.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of encrypted communications allowing interception, decryption, and modification of sensitive data in transit between OpenEdge clients and servers.
Likely Case
Man-in-the-middle attacks where attackers can intercept and potentially modify network traffic between OpenEdge components, leading to data exposure or unauthorized access.
If Mitigated
Limited impact if proper TLS certificate validation is already enforced through CA-signed certificates or network segmentation.
🎯 Exploit Status
Exploitation requires network access to intercept TLS connections; no authentication needed as this is a protocol-level vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in advisory; consult Progress support for specific version
Vendor Advisory: https://community.progress.com/s/article/Client-connections-using-default-TLS-certificates-from-OpenEdge-may-bypass-TLS-host-name-validation
Restart Required: Yes
Instructions:
1. Apply the latest OpenEdge update from Progress. 2. Replace all default TLS certificates with CA-signed certificates from recognized certificate authorities. 3. Restart OpenEdge services. 4. Verify host name validation is now enforced.
🔧 Temporary Workarounds
Replace Default Certificates
allImmediately replace OpenEdge default certificates with CA-signed certificates containing proper host name information
Consult OpenEdge documentation for certificate replacement procedures specific to your version
Network Segmentation
allIsolate OpenEdge network traffic to trusted segments to reduce attack surface
🧯 If You Can't Patch
- Replace all default TLS certificates with CA-signed certificates immediately
- Implement strict network segmentation and monitor for unusual TLS handshake patterns
🔍 How to Verify
Check if Vulnerable:
Check if OpenEdge is using default certificates by examining certificate configuration files and verifying certificates are not CA-signedCheck Version:
Consult OpenEdge documentation for version check command specific to your installationVerify Fix Applied:
Test TLS connections to verify host name validation is now enforced and default certificates are rejected📡 Detection & Monitoring
Log Indicators:
- Failed TLS handshakes with host name validation errors
- Connections using default certificate identifiers
Network Indicators:
- Unusual TLS negotiation patterns
- Connections bypassing expected certificate validation
