CVE-2022-31230
📋 TL;DR
Dell PowerScale OneFS versions 8.2.x through 9.2.x contain a broken or risky cryptographic algorithm vulnerability. A remote unprivileged attacker could exploit this to gain full system access. This affects Dell PowerScale storage systems running vulnerable OneFS versions.
💻 Affected Systems
- Dell PowerScale OneFS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote attacker gains full administrative control over the PowerScale cluster, allowing data theft, destruction, or ransomware deployment.
Likely Case
Attacker gains unauthorized access to sensitive data stored on the PowerScale system and potentially pivots to other network resources.
If Mitigated
With proper network segmentation and access controls, impact is limited to the PowerScale system itself.
🎯 Exploit Status
The vulnerability involves cryptographic weaknesses that could be exploited remotely without authentication. Specific exploit details are not publicly documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: OneFS 9.3.0.0 and later
Vendor Advisory: https://www.dell.com/support/kbdoc/en-us/000200681/dsa-2022-118-dell-emc-powerscale-onefs-security-update
Restart Required: Yes
Instructions:
1. Review Dell advisory DSA-2022-118. 2. Upgrade to OneFS 9.3.0.0 or later. 3. Reboot the PowerScale cluster after upgrade.
🔧 Temporary Workarounds
Network segmentation
allRestrict network access to PowerScale management interfaces to trusted networks only.
Access control lists
allImplement strict firewall rules to limit which IP addresses can communicate with PowerScale systems.
🧯 If You Can't Patch
- Isolate PowerScale systems in a dedicated VLAN with strict access controls.
- Implement network monitoring and intrusion detection specifically for PowerScale traffic.
🔍 How to Verify
Check if Vulnerable:
Check OneFS version via SSH: 'isi version' or web interface. If version is between 8.2.x and 9.2.x inclusive, system is vulnerable.Check Version:
isi versionVerify Fix Applied:
Verify OneFS version is 9.3.0.0 or later using 'isi version' command.📡 Detection & Monitoring
Log Indicators:
- Unauthorized authentication attempts to PowerScale management interfaces
- Unusual cryptographic operations in system logs
Network Indicators:
- Unexpected network traffic to PowerScale management ports (typically 8080, 9090)
