CVE-2017-8960
📋 TL;DR
This authentication bypass vulnerability in HPE MSA storage systems allows attackers to gain unauthorized access without valid credentials. It affects HPE MSA 1040 and MSA 2040 SAN Storage systems running vulnerable firmware versions. Attackers could potentially access sensitive storage management functions and data.
💻 Affected Systems
- HPE MSA 1040 SAN Storage
- HPE MSA 2040 SAN Storage
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of storage system allowing data theft, destruction, or ransomware deployment across connected systems.
Likely Case
Unauthorized access to storage management interface leading to data exposure, configuration changes, or denial of service.
If Mitigated
Limited impact if systems are isolated, monitored, and have additional authentication layers.
🎯 Exploit Status
Authentication bypass vulnerabilities typically have low exploitation complexity once the method is known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: GL220P009 or later
Vendor Advisory: https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-hpesbst03780en_us
Restart Required: Yes
Instructions:
1. Download firmware update GL220P009 or later from HPE support portal. 2. Backup current configuration. 3. Apply firmware update through storage management interface. 4. Reboot storage controllers as required by update process.
🔧 Temporary Workarounds
Network isolation
allRestrict access to storage management interfaces to trusted networks only
Access control lists
allImplement strict firewall rules limiting source IP addresses that can access management interfaces
🧯 If You Can't Patch
- Isolate storage management interfaces from untrusted networks and internet
- Implement additional authentication layers (VPN, jump hosts) for management access
🔍 How to Verify
Check if Vulnerable:
Check firmware version in storage management interface under System InformationCheck Version:
No CLI command - check via web management interface at System > InformationVerify Fix Applied:
Confirm firmware version is GL220P009 or later in System Information📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to management interface
- Authentication bypass patterns in web server logs
- Unexpected configuration changes
Network Indicators:
- Unusual traffic patterns to storage management ports (typically 80/443)
- Access from unexpected source IPs
SIEM Query:
source_ip NOT IN (trusted_management_ips) AND dest_port IN (80,443) AND dest_ip IN (storage_systems)
