CVE-2024-37325
📋 TL;DR
This vulnerability allows authenticated users on Azure Data Science Virtual Machines (DSVM) to elevate privileges to root/administrator level. It affects users running DSVM instances with specific configurations that expose sensitive information.
💻 Affected Systems
- Azure Data Science Virtual Machine (DSVM)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains full root/administrator control over the DSVM, enabling data theft, lateral movement, and complete system compromise.
Likely Case
Malicious or compromised users escalate privileges to install malware, access sensitive data, or disrupt operations.
If Mitigated
With proper access controls and monitoring, impact is limited to isolated instances with minimal data exposure.
🎯 Exploit Status
Exploitation requires authenticated access to the DSVM instance.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Updated DSVM images from Microsoft
Vendor Advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-37325
Restart Required: Yes
Instructions:
1. Deploy updated DSVM images from Azure Marketplace. 2. Replace existing vulnerable DSVM instances with patched versions. 3. Ensure no sensitive information remains exposed in configurations.
🔧 Temporary Workarounds
Restrict User Access
linuxLimit authenticated user access to only necessary users and implement strict privilege separation.
Remove Sensitive Information
linuxAudit and remove any exposed sensitive information from DSVM configurations accessible to users.
🧯 If You Can't Patch
- Isolate vulnerable DSVM instances from critical networks and data
- Implement enhanced monitoring for privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check if your DSVM instance uses pre-update images by comparing with Microsoft's updated image versions.Check Version:
Check Azure portal for DSVM image version or run 'cat /etc/os-release' on the instance.Verify Fix Applied:
Confirm deployment of updated DSVM images from Azure Marketplace and verify no sensitive information is exposed.📡 Detection & Monitoring
Log Indicators:
- Unexpected privilege escalation events
- Unauthorized access to sensitive files or directories
Network Indicators:
- Unusual outbound connections from DSVM instances
SIEM Query:
Search for authentication logs followed by privilege escalation patterns on DSVM hosts.
