CVE-2023-3263
📋 TL;DR
This authentication bypass vulnerability in Dataprobe iBoot PDU firmware allows attackers to obtain valid authorization tokens by exploiting special character handling in the REST API. This enables unauthorized reading of relay and power distribution state information. Organizations using Dataprobe iBoot PDU devices with vulnerable firmware are affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full administrative control over power distribution units, enabling them to remotely power cycle critical infrastructure, cause physical damage through improper power cycling, or disrupt operations by shutting down connected equipment.
Likely Case
Attackers obtain unauthorized access to power monitoring data and potentially manipulate relay states, allowing them to disrupt operations by power cycling connected devices or gather intelligence about power usage patterns.
If Mitigated
With proper network segmentation and access controls, impact is limited to unauthorized information disclosure about power states without ability to manipulate physical equipment.
🎯 Exploit Status
The vulnerability involves authentication bypass through special character manipulation, making exploitation straightforward once the technique is understood.
🛠️ 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. Backup current configuration. 3. Upload new firmware via web interface. 4. Reboot device. 5. Restore configuration if needed.
🔧 Temporary Workarounds
Network Segmentation
allIsolate iBoot PDU devices on separate VLAN with strict firewall rules limiting access to authorized management systems only.
Disable REST API
allIf REST API functionality is not required, disable it in device configuration to eliminate the attack surface.
🧯 If You Can't Patch
- Implement strict network access controls allowing only authorized IP addresses to communicate with the PDU management interface
- Monitor authentication logs for unusual patterns and implement rate limiting on authentication attempts
🔍 How to Verify
Check if Vulnerable:
Check firmware version via web interface or SSH. If version is 1.43.03312023 or earlier, device is vulnerable.Check Version:
ssh admin@[PDU_IP] 'show version' or check via web interface System Information pageVerify Fix Applied:
Verify firmware version is newer than 1.43.03312023 and test authentication with special characters in credentials.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts followed by successful login with unusual patterns
- Authentication requests containing special characters in credentials
Network Indicators:
- Unusual REST API requests to /api/auth or similar endpoints
- Traffic from unexpected source IPs to PDU management ports
SIEM Query:
source="iboot-pdu" AND (event_type="authentication" AND result="success") AND (username CONTAINS special_characters OR source_ip NOT IN allowed_ips)
