CVE-2020-24650
📋 TL;DR
This is a critical remote code execution vulnerability in HPE Intelligent Management Center (iMC) that allows attackers to execute arbitrary code by injecting malicious expressions into the legend expression language. It affects all iMC PLAT installations prior to version 7.3 (E0705P07). Attackers can exploit this without authentication to gain complete control of affected systems.
💻 Affected Systems
- HPE Intelligent Management Center (iMC)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands with highest privileges, install malware, exfiltrate sensitive data, and pivot to other network systems.
Likely Case
Remote code execution leading to system takeover, credential theft, and lateral movement within the network.
If Mitigated
Limited impact if proper network segmentation and access controls prevent exploitation attempts.
🎯 Exploit Status
CVSS 9.8 with Attack Vector: Network and Attack Complexity: Low suggests relatively easy exploitation once details are known.
🛠️ 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 the patch from HPE support portal. 2. Backup current iMC installation. 3. Apply the patch following HPE documentation. 4. Restart iMC services. 5. Verify successful update.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to iMC management interface to only trusted administrative networks
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="TRUSTED_NETWORK" port protocol="tcp" port="8080" accept'
netsh advfirewall firewall add rule name="Restrict iMC" dir=in action=allow protocol=TCP localport=8080 remoteip=TRUSTED_NETWORK
🧯 If You Can't Patch
- Isolate iMC systems from internet and restrict access to management VLAN only
- Implement network segmentation and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check iMC version via web interface or installation directory. Versions prior to 7.3 (E0705P07) are vulnerable.Check Version:
Check iMC web interface login page or imc.properties file for version informationVerify Fix Applied:
Verify version is 7.3 (E0705P07) or later and check patch installation logs.📡 Detection & Monitoring
Log Indicators:
- Unusual process execution from iMC services
- Suspicious network connections from iMC server
- Authentication failures followed by successful access
Network Indicators:
- Unusual outbound connections from iMC server
- Exploit attempts targeting iMC management ports
SIEM Query:
source="iMC_logs" AND (event_type="process_execution" AND process_name NOT IN ("expected_processes")) OR (event_type="network_connection" AND dest_ip NOT IN ("allowed_networks"))
