CVE-2024-49564
📋 TL;DR
This CVE describes an OS command injection vulnerability in Dell Unity storage systems. A low-privileged attacker with local access can execute arbitrary commands with root privileges, leading to complete system compromise. Affected systems include Dell Unity, UnityVSA, and Unity XT versions 5.4 and earlier.
💻 Affected Systems
- Dell Unity
- Dell UnityVSA
- Dell Unity XT
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover with root privileges, data exfiltration, ransomware deployment, or destruction of storage systems.
Likely Case
Privilege escalation from low-privileged user to root, enabling persistence, lateral movement, and data access.
If Mitigated
Limited impact if proper network segmentation, least privilege access, and monitoring are implemented.
🎯 Exploit Status
Exploitation requires local access and low privileges; no public exploit available as of analysis.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 5.5 or later
Restart Required: No
Instructions:
1. Review Dell advisory DSA-2025-116. 2. Download and apply the latest firmware update from Dell Support. 3. Verify update completion without system restart required.
🔧 Temporary Workarounds
Restrict Local Access
allLimit local console and SSH access to trusted administrative users only.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Dell Unity systems from general user networks.
- Enforce least privilege access controls and monitor for unusual local login activity.
🔍 How to Verify
Check if Vulnerable:
Check system version via Unity management interface or CLI; if version is 5.4 or earlier, system is vulnerable.Check Version:
Check via Unity web interface or use system-specific CLI commands provided by Dell.Verify Fix Applied:
Confirm system version is 5.5 or later after applying the update.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
