CVE-2020-24629
📋 TL;DR
CVE-2020-24629 is an authentication bypass vulnerability in HPE Intelligent Management Center's urlaccesscontroller component. Attackers can remotely bypass authentication mechanisms to gain unauthorized access to the iMC platform. This affects all HPE iMC installations running versions prior to iMC PLAT 7.3 (E0705P07).
💻 Affected Systems
- HPE Intelligent Management Center (iMC)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the iMC management platform, allowing attackers to gain administrative control, access sensitive network management data, and potentially pivot to managed network devices.
Likely Case
Unauthorized access to the iMC web interface, enabling attackers to view configuration data, modify network settings, and potentially execute arbitrary code.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access to iMC interfaces.
🎯 Exploit Status
The vulnerability allows unauthenticated remote exploitation with low complexity. While no public PoC exists, the nature of authentication bypass vulnerabilities makes weaponization likely.
🛠️ 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 iMC PLAT 7.3 (E0705P07) patch from HPE support portal. 2. Backup current iMC installation and database. 3. Apply the patch following HPE's installation guide. 4. Restart iMC services and verify functionality.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to iMC web interface using firewall rules or network segmentation.
Web Application Firewall
allDeploy a WAF with rules to detect and block authentication bypass attempts.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate iMC from untrusted networks
- Deploy intrusion detection systems to monitor for authentication bypass attempts
🔍 How to Verify
Check if Vulnerable:
Check iMC version via web interface or installation directory. Navigate to Help > About in iMC web interface.Check Version:
Check imc.properties file or use iMC web interface Help > About menuVerify Fix Applied:
Verify version is iMC PLAT 7.3 (E0705P07) or later and test authentication mechanisms.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication patterns
- Access to urlaccesscontroller endpoints without proper authentication
- Failed login attempts followed by successful access
Network Indicators:
- HTTP requests to iMC web interface without authentication cookies
- Unusual traffic patterns to iMC management ports
SIEM Query:
source="iMC_logs" AND (event_type="authentication" AND result="success" AND user_agent="unknown" OR url CONTAINS "urlaccesscontroller")
