CVE-2023-28088
📋 TL;DR
CVE-2023-28088 is a vulnerability in HPE OneView where diagnostic dumps may expose SAN switch administrative credentials. This affects HPE OneView users who have configured SAN switch management. Attackers who obtain these dumps could gain administrative access to SAN infrastructure.
💻 Affected Systems
- HPE OneView
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative credentials to SAN switches, allowing them to reconfigure storage networks, disrupt operations, or exfiltrate sensitive data from storage systems.
Likely Case
Internal attackers or those with access to diagnostic files obtain SAN switch credentials, potentially leading to unauthorized storage network modifications.
If Mitigated
With proper access controls and monitoring, credential exposure is limited, and compromised credentials can be quickly detected and rotated.
🎯 Exploit Status
Exploitation requires access to diagnostic dump files, which typically requires some level of system access or privilege.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: HPE OneView 8.4
Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=hpesbgn04469en_us

Instructions:
1. Backup current configuration. 2. Download HPE OneView 8.4 from HPE support portal. 3. Follow HPE OneView upgrade documentation. 4. Verify upgrade completion and functionality.
🔧 Temporary Workarounds
Restrict diagnostic dump access
linuxLimit access to diagnostic dump files and directories to authorized administrators only.
chmod 600 /path/to/diagnostic/dumps
chown root:root /path/to/diagnostic/dumps
Rotate SAN switch credentials
allChange SAN switch administrative credentials to limit exposure window.
🧯 If You Can't Patch
- Implement strict access controls on diagnostic dump directories and files
- Regularly rotate SAN switch administrative credentials and monitor for unauthorized access
🔍 How to Verify
Check if Vulnerable:
Check HPE OneView version via web interface or CLI. Versions below 8.4 are vulnerable if SAN switch management is configured.Check Version:
ovcli versionVerify Fix Applied:
Verify HPE OneView version is 8.4 or later and confirm diagnostic dumps no longer contain plaintext SAN credentials.📡 Detection & Monitoring
