- Dell EMC OpenManage Enterprise-Modular
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the management platform leading to data exfiltration, system manipulation, and lateral movement to managed infrastructure.
Likely Case
Unauthorized data access, configuration changes, and potential privilege escalation within the management system.
If Mitigated
Limited impact due to proper access controls, network segmentation, and monitoring preventing successful exploitation.
🎯 Exploit Status
SQL injection vulnerabilities are typically straightforward to exploit once identified. Requires authenticated access with high privileges.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: OpenManage Enterprise 3.2 or later, OpenManage Enterprise-Modular 1.10.00 or later

🔧 Temporary Workarounds
Restrict Privileged Access
allLimit the number of users with high privileges to only those who absolutely need them.
Network Segmentation
allPlace OME/OME-M systems in isolated management networks with strict access controls.
🧯 If You Can't Patch
- Implement strict network access controls to limit which systems can reach the management interface
- Enforce principle of least privilege for all user accounts and implement multi-factor authentication
🔍 How to Verify
Check if Vulnerable:
Check the version in the OME/OME-M web interface under Help > About or via CLI using version commands specific to each product.Check Version:
Product-specific - check web interface or consult Dell documentation for CLI commandsVerify Fix Applied:
Verify the version is 3.2 or higher for OME, or 1.10.00 or higher for OME-M. Test SQL injection attempts should be blocked.📡 Detection & Monitoring
