CVE-2022-32481
📋 TL;DR
Dell PowerProtect Cyber Recovery versions before 19.11 contain a privilege escalation vulnerability where authenticated users with lower privileges can chain Docker commands to gain root access. This affects virtual appliance deployments, allowing attackers to take complete control of affected systems.
💻 Affected Systems
- Dell PowerProtect Cyber Recovery
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root access, allowing data theft, ransomware deployment, or destruction of recovery capabilities.
Likely Case
Unauthorized administrative access leading to data exfiltration, configuration changes, or lateral movement within the environment.
If Mitigated
Limited impact if proper network segmentation and access controls prevent exploitation attempts.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of Docker command chaining techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 19.11 or later
Vendor Advisory: https://support.emc.com/kb/000201213
Restart Required: Yes
Instructions:
1. Backup current configuration. 2. Download and install version 19.11 or later from Dell support portal. 3. Apply update following Dell documentation. 4. Restart the appliance.
🔧 Temporary Workarounds
Restrict Docker Access
linuxLimit Docker command execution to authorized administrators only
sudo usermod -aG docker <admin_users>
sudo chmod 750 /var/run/docker.sock
🧯 If You Can't Patch
- Implement strict access controls and limit user permissions to essential functions only
- Monitor Docker command execution and audit logs for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check Cyber Recovery version via web interface or command line. Versions below 19.11 are vulnerable.Check Version:
ssh admin@<appliance_ip> 'cat /etc/version' or check web admin interfaceVerify Fix Applied:
Confirm version is 19.11 or later and test that non-admin users cannot execute privileged Docker commands.📡 Detection & Monitoring
