CVE-2024-47481
📋 TL;DR
Dell Data Lakehouse versions 1.0.0.0 and 1.1.0 contain an improper access control vulnerability that allows unauthenticated attackers on adjacent networks to cause denial of service. This affects organizations using these specific Dell Data Lakehouse versions in their data infrastructure. The vulnerability stems from insufficient access restrictions that can be exploited without credentials.
💻 Affected Systems
- Dell Data Lakehouse
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption of Dell Data Lakehouse systems, potentially affecting dependent applications and data processing workflows.
Likely Case
Temporary service degradation or unavailability of the Data Lakehouse service until systems are restarted or the attack stops.
If Mitigated
Minimal impact if network segmentation isolates the Data Lakehouse from untrusted adjacent networks and proper access controls are implemented.
🎯 Exploit Status
The vulnerability can be exploited without authentication from adjacent networks, making it relatively easy to trigger if network access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Dell advisory DSA-2024-419 for specific patched versions
Restart Required: Yes
Instructions:
1. Review Dell advisory DSA-2024-419. 2. Download and apply the security update from Dell support. 3. Restart the Data Lakehouse service or system as required. 4. Verify the update was successful.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Dell Data Lakehouse systems from untrusted network segments using firewalls or VLANs
Access Control Lists
allImplement strict network access controls to limit which systems can communicate with Data Lakehouse
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Data Lakehouse from all untrusted adjacent networks
- Monitor network traffic to Data Lakehouse systems for unusual patterns or DoS attempts
