CVE-2024-32852
📋 TL;DR
Dell PowerScale OneFS versions 8.2.2.x through 9.7.0.0 use broken or risky cryptographic algorithms, allowing unprivileged network attackers to potentially exploit this vulnerability to cause data leaks. 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
Sensitive data stored on PowerScale systems could be decrypted or intercepted by attackers, leading to data breaches, compliance violations, and reputational damage.
Likely Case
Attackers could decrypt weakly encrypted data or perform man-in-the-middle attacks to intercept data in transit to/from PowerScale systems.
If Mitigated
With proper network segmentation and access controls, the attack surface is reduced, limiting potential data exposure to segmented network zones.
🎯 Exploit Status
Exploitation requires network access to vulnerable systems and knowledge of the weak cryptographic implementation details.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: OneFS 9.7.0.1 and later
Vendor Advisory: https://www.dell.com/support/kbdoc/en-us/000226569/dsa-2024-255-security-update-for-dell-powerscale-onefs-for-multiple-security-vulnerabilities
Restart Required: Yes
Instructions:
1. Review Dell advisory DSA-2024-255. 2. Download and apply the OneFS update to version 9.7.0.1 or later. 3. Reboot the PowerScale cluster as required by the update process.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to PowerScale systems to only trusted networks and required services.
Encryption Configuration Review
linuxAudit and disable use of weak cryptographic algorithms in OneFS configuration where possible.
🧯 If You Can't Patch
- Implement strict network access controls and firewall rules to limit exposure to PowerScale systems.
- Monitor for unusual network traffic patterns or decryption attempts targeting PowerScale systems.
🔍 How to Verify
Check if Vulnerable:
Check the OneFS version using the CLI command: 'isi version'. If version is between 8.2.2.x and 9.7.0.0 inclusive, the system is vulnerable.Check Version:
isi versionVerify Fix Applied:
After patching, verify the OneFS version is 9.7.0.1 or later using 'isi version' command.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication failures, unexpected cryptographic algorithm usage in logs
Network Indicators:
