CVE-2024-53298
📋 TL;DR
Dell PowerScale OneFS versions 9.5.0.0 through 9.10.0.1 have a critical missing authorization vulnerability in NFS export. Unauthenticated remote attackers can potentially read, modify, and delete arbitrary files, leading to full system compromise. All organizations running affected versions are at risk.
💻 Affected Systems
- Dell PowerScale OneFS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover with unauthorized access to all files, potential data destruction, and lateral movement to other systems.
Likely Case
Unauthorized access to sensitive files, data exfiltration, and potential ransomware deployment.
If Mitigated
Limited impact if network segmentation isolates NFS services and access controls are properly configured.
🎯 Exploit Status
Vulnerability allows unauthenticated access, making exploitation straightforward for attackers with network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 9.10.0.2 or later
Vendor Advisory: https://www.dell.com/support/kbdoc/en-us/000326339/dsa-2025-208-security-update-for-dell-powerscale-onefs-for-multiple-security-vulnerabilities
Restart Required: Yes
Instructions:
1. Backup all critical data. 2. Download the latest OneFS patch from Dell Support. 3. Apply the patch following Dell's upgrade procedures. 4. Restart the system as required. 5. Verify the patch is applied successfully.
🔧 Temporary Workarounds
Disable NFS Exports
linuxTemporarily disable all NFS exports to prevent exploitation.
isi nfs exports delete --all
Restrict NFS Network Access
linuxUse firewall rules to restrict NFS access to trusted IPs only.
iptables -A INPUT -p tcp --dport 2049 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 2049 -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate NFS services from untrusted networks.
- Enable detailed logging and monitoring for all NFS access attempts.
🔍 How to Verify
Check if Vulnerable:
Check OneFS version with 'isi version' command. If version is between 9.5.0.0 and 9.10.0.1 inclusive, system is vulnerable.Check Version:
isi versionVerify Fix Applied:
Run 'isi version' command and verify version is 9.10.0.2 or later.📡 Detection & Monitoring
