Notes: All configurations of affected versions are vulnerable. Requires local authenticated access to the PowerScale system.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system unavailability or data inaccessibility due to critical resource manipulation by a local attacker.

🟠

Likely Case

Partial service disruption affecting specific storage operations or performance degradation.

🟢

If Mitigated

Minimal impact with proper access controls limiting local user privileges.

🌐 Internet-Facing: LOW - Requires local authentication, not directly exploitable over network.
🏢 Internal Only: MEDIUM - Local authenticated attackers could disrupt storage services affecting dependent systems.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires local authenticated access. No public exploit code is known at this time.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Apply updates per Dell advisory DSA-2024-417

Vendor Advisory: https://www.dell.com/support/kbdoc/en-us/000242681/dsa-2024-417-security-update-for-dell-powerscale-onefs-for-security-vulnerability

Restart Required: Yes

Instructions:

1. Review Dell advisory DSA-2024-417. 2. Download appropriate OneFS update from Dell Support. 3. Apply update following Dell PowerScale update procedures. 4. Reboot system as required.

🔧 Temporary Workarounds

Restrict Local User Access

linux

Limit local user accounts and privileges to essential personnel only.

Review and remove unnecessary local accounts using OneFS user management tools

🧯 If You Can't Patch

  • Implement strict access controls limiting local user privileges to minimum required.
  • Monitor system logs for unusual local user activity or resource access patterns.

🔍 How to Verify

Check if Vulnerable:

Check OneFS version with command: 'isi version'. If version is between 8.2.2.x and 9.8.0.x inclusive, system is vulnerable.

Check Version:

isi version

Verify Fix Applied:

Verify updated version with 'isi version' and confirm it's above affected range. Check Dell advisory for specific fixed versions.

📡 Detection & Monitoring

Log Indicators:

  • Unusual local user activity accessing system resources
  • Permission modification events in system logs
  • Denial of service alerts from PowerScale monitoring

Network Indicators:

  • Increased failed storage requests from dependent systems
  • Unusual management interface activity

SIEM Query:

source="powerscale" AND (event_type="permission_change" OR event_type="resource_access" OR event_type="dos_alert")
