CVE-2022-47320
📋 TL;DR
CVE-2022-47320 is a vulnerability in Dataprobe iBoot Power Distribution Units (PDUs) that allows unauthenticated attackers to execute arbitrary code via the discovery protocol. This affects organizations using these network-connected power management devices for data centers, industrial control systems, and critical infrastructure.
💻 Affected Systems
- Dataprobe iBoot-PDU
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of power distribution infrastructure allowing attackers to remotely power cycle critical equipment, disrupt operations, and maintain persistent access to industrial networks.
Likely Case
Unauthorized power manipulation of connected devices leading to service disruption, equipment damage, and potential data loss.
If Mitigated
Limited impact with proper network segmentation and access controls preventing external exploitation.
🎯 Exploit Status
Exploitation requires network access to port 9131/UDP but no authentication credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Firmware version 1.42.06162022
Vendor Advisory: https://dataprobe.com/support/iboot-pdu/local_upgrade_pdu_procedure.pdf
Restart Required: Yes
Instructions:
1. Download firmware version 1.42.06162022 from Dataprobe support site. 2. Log into iBoot-PDU web interface. 3. Navigate to System > Firmware Upgrade. 4. Upload the firmware file. 5. Wait for automatic reboot and verification.
🔧 Temporary Workarounds
Disable Discovery Protocol
allTurn off the vulnerable discovery service to prevent exploitation.
Web Interface: System > Network > Discovery Protocol > Disable
Network Segmentation
allIsolate iBoot-PDU devices on separate VLAN with strict firewall rules.
Firewall rule: deny all traffic to port 9131/udp from untrusted networks
🧯 If You Can't Patch
- Implement strict network access controls allowing only management traffic from authorized IPs
- Monitor port 9131/UDP for unauthorized access attempts and anomalous traffic patterns
🔍 How to Verify
Check if Vulnerable:
Check firmware version via web interface: System > About. If version is earlier than 1.42.06162022, device is vulnerable.Check Version:
Web interface navigation only - no CLI command available.Verify Fix Applied:
Confirm firmware version shows 1.42.06162022 or later in System > About page.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to port 9131
- Unexpected firmware modification logs
- Multiple power cycle events from single source
Network Indicators:
- UDP traffic to port 9131 from unauthorized sources
- Unusual power control commands over network
