CVE-2023-28083
📋 TL;DR
A cross-site scripting (XSS) vulnerability in HPE Integrated Lights-Out (iLO) management interfaces allows attackers to inject malicious scripts that execute in users' browsers when viewing compromised pages. This affects iLO 4, 5, and 6 firmware versions before HPE's security updates. Attackers could steal credentials, hijack sessions, or perform unauthorized actions on the iLO management interface.
💻 Affected Systems
- HPE Integrated Lights-Out 6
- HPE Integrated Lights-Out 5
- HPE Integrated Lights-Out 4
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of iLO management interface leading to server control, credential theft, and lateral movement to managed servers.
Likely Case
Session hijacking, credential theft, and unauthorized configuration changes to iLO settings.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access to iLO interfaces.
🎯 Exploit Status
XSS vulnerabilities typically have low exploitation complexity but require user interaction or social engineering
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Latest firmware updates from HPE
Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=hpesbhf04456en_us
Restart Required: Yes
Instructions:
1. Download latest iLO firmware from HPE Support Portal. 2. Upload firmware via iLO web interface or HPE OneView. 3. Apply update and reboot iLO controller. 4. Verify firmware version after reboot.
🔧 Temporary Workarounds
Network Segmentation
allRestrict access to iLO management interfaces to trusted networks only
Access Control Lists
allImplement firewall rules to limit iLO interface access to authorized IPs
🧯 If You Can't Patch
- Implement strict network segmentation to isolate iLO interfaces
- Use VPN or jump hosts for iLO access instead of direct exposure
🔍 How to Verify
Check if Vulnerable:
Check iLO firmware version via web interface or SSH and compare against HPE advisoryCheck Version:
ssh [iLO-IP] 'show /map1/firmware1' or check via web interface under Information > FirmwareVerify Fix Applied:
Confirm firmware version matches or exceeds patched versions listed in HPE advisory📡 Detection & Monitoring
Log Indicators:
- Unusual iLO web interface access patterns
- Multiple failed login attempts followed by successful login
- Suspicious JavaScript payloads in web logs
Network Indicators:
- Unexpected external connections to iLO management ports (typically 443/17990)
- Traffic patterns suggesting credential harvesting
SIEM Query:
