CVE-2023-3259
📋 TL;DR
This vulnerability allows attackers to bypass authentication on Dataprobe iBoot PDU devices by manipulating a cookie's IP address field, redirecting the device to connect to a malicious database. Successful exploitation grants administrator privileges, enabling power manipulation, user account modification, and data exfiltration. Organizations using affected Dataprobe iBoot PDU firmware versions are at risk.
💻 Affected Systems
- Dataprobe iBoot PDU
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of power distribution units allowing attackers to shut down critical infrastructure, create persistent backdoors, and exfiltrate sensitive user data.
Likely Case
Unauthorized power cycling of connected equipment leading to service disruption and potential data loss from connected systems.
If Mitigated
Limited impact with proper network segmentation and monitoring detecting anomalous database connection attempts.
🎯 Exploit Status
Exploitation requires cookie manipulation but no authentication, making it accessible to attackers with network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Firmware version newer than 1.43.03312023
Vendor Advisory: https://www.dataprobe.com/support/iboot-pdu/
Restart Required: Yes
Instructions:
1. Download latest firmware from Dataprobe support portal. 2. Log into iBoot PDU web interface. 3. Navigate to System > Firmware Update. 4. Upload new firmware file. 5. Confirm update and allow device to restart.
🔧 Temporary Workarounds
Network Segmentation
allIsolate iBoot PDU devices on separate VLAN with strict firewall rules limiting access to management interfaces.
Access Control Lists
allImplement IP-based access controls to restrict management interface access to authorized administrative networks only.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate PDU devices from untrusted networks
- Deploy network monitoring to detect anomalous database connection attempts and cookie manipulation
🔍 How to Verify
Check if Vulnerable:
Check firmware version in web interface under System > About. If version is 1.43.03312023 or earlier, device is vulnerable.Check Version:
curl -k https://<device-ip>/cgi-bin/about.cgi | grep 'Firmware Version'Verify Fix Applied:
After firmware update, verify version shows newer than 1.43.03312023 and test authentication bypass attempts fail.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful administrative actions
- Database connection attempts to non-standard IP addresses
Network Indicators:
- HTTP requests with manipulated 'iBootPduSiteAuth' cookie values
- Unexpected outbound database connections from PDU devices
SIEM Query:
source="iboot-pdu-logs" AND (cookie="iBootPduSiteAuth" AND NOT dest_ip IN [authorized_db_ips])
