CVE-2020-14606
📋 TL;DR
This critical vulnerability in Oracle SD-WAN Edge allows unauthenticated attackers with network access via HTTP to completely compromise the device. It affects Oracle SD-WAN Edge versions 8.2 and 9.0, potentially impacting additional connected products. Successful exploitation results in full system takeover with confidentiality, integrity, and availability impacts.
💻 Affected Systems
- Oracle SD-WAN Edge
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of Oracle SD-WAN Edge device leading to network disruption, data exfiltration, and lateral movement to connected systems.
Likely Case
Attackers gain full control of SD-WAN Edge to intercept, modify, or block network traffic, potentially affecting entire network segments.
If Mitigated
Limited impact if device is isolated behind firewalls with strict network access controls and intrusion prevention systems.
🎯 Exploit Status
CVSS 10.0 indicates trivial exploitation via HTTP without authentication. No public exploit code identified in references.

🔧 Temporary Workarounds
Network Segmentation
allRestrict HTTP access to Oracle SD-WAN Edge management interface using firewall rules
Access Control
allImplement strict network access controls to limit which systems can communicate with SD-WAN Edge HTTP interface
🧯 If You Can't Patch
- Isolate Oracle SD-WAN Edge devices in separate network segments with strict firewall rules
- Implement network monitoring and intrusion detection for unusual HTTP traffic to SD-WAN Edge interfaces
🔍 How to Verify
Check if Vulnerable:
Check Oracle SD-WAN Edge version via web interface or CLI. If version is 8.2 or 9.0, device is vulnerable.Check Version:
Check via web interface or use device-specific CLI commands (varies by deployment)Verify Fix Applied:
Verify version is updated beyond affected versions (8.2, 9.0) and check Oracle advisory for specific patched versions.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP requests to SD-WAN Edge UI
