CVE-2024-42062
📋 TL;DR
A privilege escalation vulnerability in Apache CloudStack allows domain admin accounts to query API and secret keys of all account-users, including root admin. This enables attackers with domain admin access to gain root privileges and compromise CloudStack-managed infrastructure. Affects CloudStack versions 4.10.0 through 4.19.1.0.
💻 Affected Systems
- Apache CloudStack
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of CloudStack infrastructure: root admin privileges obtained, allowing full control over all resources, data exfiltration, resource destruction, and denial of service.
Likely Case
Domain admin escalates to root admin, accesses sensitive data, modifies configurations, and potentially deploys malicious resources across the cloud environment.
If Mitigated
Limited to domain admin's existing scope if proper key rotation and monitoring are in place, but still represents significant privilege escalation risk.
🎯 Exploit Status
Exploitation requires domain admin access. No public exploit code has been released as of the advisory date.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.18.2.3 or 4.19.1.1 or later
Vendor Advisory: https://cloudstack.apache.org/blog/security-release-advisory-4.19.1.1-4.18.2.3
Restart Required: Yes
Instructions:
1. Backup CloudStack configuration and database. 2. Download patched version from Apache CloudStack website. 3. Stop CloudStack services. 4. Apply the update according to CloudStack upgrade documentation. 5. Restart services. 6. Regenerate all account-user API and secret keys.
🔧 Temporary Workarounds
Restrict Domain Admin API Access
allTemporarily limit or monitor domain admin API usage to detect suspicious key query activities.
# Monitor API logs for key queries
# grep 'listKeys' /var/log/cloudstack/management/*.log
# Review domain admin API permissions in CloudStack UI
🧯 If You Can't Patch
- Immediately regenerate all account-user API and secret keys to invalidate any potentially compromised credentials.
- Implement strict monitoring of domain admin activities, particularly API key queries, and consider temporary reduction of domain admin privileges.
🔍 How to Verify
Check if Vulnerable:
Check CloudStack version via management server: # cat /etc/cloudstack-release or check CloudStack UI admin dashboard for version number.Check Version:
# cat /etc/cloudstack-release 2>/dev/null || grep version /usr/share/cloudstack-management/version 2>/dev/nullVerify Fix Applied:
Confirm version is 4.18.2.3, 4.19.1.1, or later. Test that domain admin can no longer query API keys of users outside their domain.📡 Detection & Monitoring
Log Indicators:
- Unusual API key query patterns from domain admin accounts
- Multiple listKeys API calls in short timeframes
- Domain admin accounts accessing root admin resources
Network Indicators:
- Increased API traffic from domain admin accounts to key management endpoints
- Unusual authentication patterns following key queries
