CVE-2020-7154
📋 TL;DR
CVE-2020-7154 is an expression language injection vulnerability in HPE Intelligent Management Center (iMC) that allows remote attackers to execute arbitrary code. This affects iMC PLAT versions prior to 7.3 (E0705P07). Attackers can exploit this without authentication to gain full control of affected systems.
💻 Affected Systems
- HPE Intelligent Management Center (iMC)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining administrative privileges, data exfiltration, lateral movement within network, and persistent backdoor installation.
Likely Case
Remote code execution leading to system takeover, credential theft, and deployment of ransomware or other malware.
If Mitigated
Limited impact if system is isolated, patched, or has network segmentation preventing external access.
🎯 Exploit Status
Exploitation is straightforward with publicly available proof-of-concept code. No authentication required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: iMC PLAT 7.3 (E0705P07) or later
Vendor Advisory: https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbnw04036en_us
Restart Required: Yes
Instructions:
1. Download patch from HPE support portal. 2. Backup current iMC installation. 3. Apply patch following HPE documentation. 4. Restart iMC services. 5. Verify successful update.
🔧 Temporary Workarounds
Network Segmentation
linuxRestrict network access to iMC management interface
iptables -A INPUT -p tcp --dport [iMC_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
iptables -A INPUT -p tcp --dport [iMC_PORT] -j DROP
Web Application Firewall
allDeploy WAF with expression language injection protection rules
🧯 If You Can't Patch
- Isolate iMC system from internet and restrict internal access to trusted networks only
- Implement strict network monitoring and alerting for suspicious activity targeting iMC
🔍 How to Verify
Check if Vulnerable:
Check iMC version via web interface or command line. If version is earlier than PLAT 7.3 (E0705P07), system is vulnerable.Check Version:
Check iMC web interface login page or run version check command specific to iMC installationVerify Fix Applied:
Verify iMC version is PLAT 7.3 (E0705P07) or later. Test if expression language injection attempts are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual expression language syntax in web requests
- Multiple failed login attempts followed by successful access
- Suspicious process creation from iMC service account
Network Indicators:
- Unusual outbound connections from iMC server
- Traffic patterns indicating data exfiltration
- Requests containing expression language payloads
