CVE-2024-30092

8.0 HIGH

📋 TL;DR

This vulnerability allows an authenticated attacker on a guest virtual machine to execute arbitrary code on the Hyper-V host. It affects Windows systems running Hyper-V with vulnerable versions. Successful exploitation could lead to complete host compromise.

💻 Affected Systems

Products:
  • Windows Hyper-V
Versions: Specific Windows versions as listed in Microsoft advisory
Operating Systems: Windows Server with Hyper-V role enabled, Windows 10/11 Pro/Enterprise with Hyper-V
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects systems with Hyper-V enabled. Guest-to-host escape vulnerability.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of the Hyper-V host, allowing attacker to control all guest VMs, access host data, and pivot to other systems.

🟠

Likely Case

Attacker gains control of the Hyper-V host from a compromised guest VM, leading to data theft, lateral movement, and disruption of virtualized services.

🟢

If Mitigated

Limited impact due to network segmentation, strict access controls, and monitoring preventing successful exploitation.

🌐 Internet-Facing: LOW - Hyper-V hosts should not be directly internet-facing; exploitation requires guest VM access.
🏢 Internal Only: HIGH - Internal attackers with guest VM access can exploit this to compromise virtualization infrastructure.

🎯 Exploit Status

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

Requires authenticated access to a guest VM. No public exploit available at time of analysis.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Microsoft Security Update Guide for specific KB numbers

Vendor Advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-30092

Restart Required: Yes

Instructions:

1. Apply latest Windows security updates from Microsoft
2. Restart Hyper-V host after patching
3. Verify patch installation via Windows Update history

🔧 Temporary Workarounds

Disable Hyper-V

windows

Remove Hyper-V role if not required

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

Network segmentation

all

Isolate Hyper-V management networks from production networks

🧯 If You Can't Patch

  • Implement strict access controls to guest VMs
  • Monitor for unusual guest-to-host communication patterns

🔍 How to Verify

Check if Vulnerable:

Check Windows version and Hyper-V role status against Microsoft advisory

Check Version:

systeminfo | findstr /B /C:"OS Name" /C:"OS Version"

Verify Fix Applied:

Verify Windows Update shows the security patch installed and check system version

📡 Detection & Monitoring

Log Indicators:

  • Unusual process creation from Hyper-V components
  • Guest VM attempting privileged operations on host

Network Indicators:

  • Unexpected network traffic between guest VMs and host management interfaces

SIEM Query:

Process creation where parent process contains 'vmwp' or 'hvhost' with unusual command line arguments
