CVE-2020-14324
📋 TL;DR
This CVE-2020-14324 is an authenticated OS command injection vulnerability in Red Hat CloudForms that allows attackers to execute arbitrary commands on the server. It affects authenticated users during conversion host setup through Infrastructure Migration Solution. All active versions before 5.11.7.0 are vulnerable.
💻 Affected Systems
- Red Hat CloudForms
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full compromise of CloudForms server leading to data exfiltration, lateral movement within the environment, and potential complete system takeover.
Likely Case
Privilege escalation leading to unauthorized access to sensitive data and configuration information stored in CloudForms.
If Mitigated
Limited impact due to network segmentation and restricted authenticated user access, but still potential for data exposure.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authenticated. No public exploit code available but trivial to weaponize.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.11.7.0 or later
Vendor Advisory: https://access.redhat.com/security/cve/cve-2020-14324
Restart Required: Yes
Instructions:
1. Update CloudForms to version 5.11.7.0 or later. 2. Apply Red Hat security updates. 3. Restart CloudForms services. 4. Verify update completion.
🔧 Temporary Workarounds
Disable Infrastructure Migration Solution
allTemporarily disable the vulnerable feature until patching can be completed
# Disable via CloudForms UI or API - no direct command
Restrict authenticated user access
allLimit which users can access conversion host setup functionality
# Configure role-based access controls in CloudForms
🧯 If You Can't Patch
- Implement strict network segmentation to isolate CloudForms from critical systems
- Enforce least privilege access controls and monitor all authenticated user activity
🔍 How to Verify
Check if Vulnerable:
Check CloudForms version via web interface or 'vmdb' database versionCheck Version:
# Check via CloudForms UI or database: SELECT * FROM schema_migrations ORDER BY version DESC LIMIT 1;Verify Fix Applied:
Verify version is 5.11.7.0 or later and test conversion host setup functionality📡 Detection & Monitoring
