CVE-2020-14705
📋 TL;DR
This critical vulnerability in Oracle GoldenGate's Process Management component allows unauthenticated attackers on the same network segment to completely compromise the GoldenGate service. Attackers can achieve remote code execution and take over the Oracle GoldenGate installation, potentially impacting connected systems. Only versions prior to 19.1.0.0.0 are affected.
💻 Affected Systems
- Oracle GoldenGate
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of Oracle GoldenGate leading to data exfiltration, integrity loss, service disruption, and potential lateral movement to connected databases and systems.
Likely Case
Attackers gain full control of GoldenGate processes, enabling data manipulation, credential theft, and disruption of data replication services.
If Mitigated
With proper network segmentation and access controls, impact is limited to the isolated GoldenGate environment only.
🎯 Exploit Status
CVSS indicates easily exploitable by unauthenticated attackers on adjacent network. No public exploit code confirmed.

🔧 Temporary Workarounds
Network Segmentation
allIsolate Oracle GoldenGate servers on dedicated VLANs with strict access controls
Firewall Rules
allImplement strict firewall rules to limit access to GoldenGate ports from trusted sources only
🧯 If You Can't Patch
- Implement strict network segmentation to isolate GoldenGate servers from untrusted networks
- Deploy host-based firewalls and monitor for unauthorized access attempts
🔍 How to Verify
Check if Vulnerable:
Check Oracle GoldenGate version: 'ggsci' command then 'info all' or check installation directory version filesCheck Version:
ggsci -> info all (shows version) or check VERSION.txt in installation directoryVerify Fix Applied:
Verify version is 19.1.0.0.0 or later using same commands and ensure no known vulnerabilities in current version📡 Detection & Monitoring
