CVE-2020-7197
📋 TL;DR
CVE-2020-7197 is a critical authentication bypass vulnerability in HPE StoreServ Management Console (SSMC) 3.7.0.0 that allows remote attackers to gain unauthorized access to the management interface without valid credentials. This affects organizations using HPE 3PAR storage arrays managed through SSMC. The vulnerability enables attackers to potentially control storage management functions remotely.
💻 Affected Systems
- HPE StoreServ Management Console (SSMC)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full administrative control over storage management console, potentially disrupting storage operations, accessing sensitive configuration data, or compromising connected storage arrays.
Likely Case
Unauthorized access to management interface leading to configuration changes, data exposure, or service disruption of storage infrastructure.
If Mitigated
Limited impact if console is isolated in management network with strict access controls, though authentication bypass still presents significant risk.
🎯 Exploit Status
Authentication bypass vulnerabilities typically have low exploitation complexity once the bypass method is known. No public exploit code was found in references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.7.1.1 or later
Vendor Advisory: https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbst04045en_us
Restart Required: Yes
Instructions:
1. Download SSMC 3.7.1.1 or later from HPE support portal. 2. Backup current SSMC configuration. 3. Deploy updated SSMC version following HPE installation guide. 4. Verify functionality post-upgrade.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict network access to SSMC management interface to only trusted management networks
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="TRUSTED_NETWORK" port port="SSMC_PORT" protocol="tcp" accept'
iptables -A INPUT -s TRUSTED_NETWORK -p tcp --dport SSMC_PORT -j ACCEPT
Access Control Lists
windowsImplement strict network ACLs to limit SSMC access to authorized IP addresses only
netsh advfirewall firewall add rule name="SSMC_Access" dir=in action=allow protocol=TCP localport=SSMC_PORT remoteip=TRUSTED_IP
🧯 If You Can't Patch
- Isolate SSMC instance in dedicated management VLAN with strict firewall rules
- Implement network-based authentication (VPN, jump host) before accessing SSMC interface
🔍 How to Verify
Check if Vulnerable:
Check SSMC version in web interface or via SSH to appliance: cat /opt/3PAR/ssmc/version.txtCheck Version:
cat /opt/3PAR/ssmc/version.txt || grep -i version /opt/3PAR/ssmc/*.propertiesVerify Fix Applied:
Verify version is 3.7.1.1 or higher and test authentication bypass attempts fail📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful access from same IP
- Access from unexpected IP addresses
- Authentication logs showing bypass patterns
Network Indicators:
- Direct HTTP/HTTPS requests to SSMC from unauthorized networks
- Traffic to SSMC without preceding authentication requests
