CVE-2024-22269
📋 TL;DR
This vulnerability allows a malicious actor with local administrative privileges on a VMware virtual machine to read privileged information from hypervisor memory via the vbluetooth device. It affects VMware Workstation and Fusion users running vulnerable versions. The attacker must already have administrative access within the guest VM to exploit this.
💻 Affected Systems
- VMware Workstation
- VMware Fusion
📦 What is this software?
Fusion by Vmware
⚠️ Risk & Real-World Impact
Worst Case
An attacker with administrative access to a guest VM could extract sensitive hypervisor memory contents, potentially including credentials, encryption keys, or other VM data from the host system.
Likely Case
An insider threat or compromised VM with administrative privileges could access memory contents from other VMs or the host system, leading to data exfiltration or lateral movement.
If Mitigated
With proper access controls limiting administrative privileges within VMs and network segmentation, the impact is reduced to isolated VM compromise without host system access.
🎯 Exploit Status
Requires local administrative access within the VM and knowledge of memory structures. No public exploit code available at disclosure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Workstation 17.5.2, Fusion 13.5.2
Vendor Advisory: https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/24280
Restart Required: Yes
Instructions:
1. Download the latest version from VMware website. 2. Install the update. 3. Restart the host system. 4. Verify the update was successful.
🔧 Temporary Workarounds
Disable vbluetooth device
allRemove or disable the virtual Bluetooth device in VM settings to prevent exploitation
In VM settings: Remove Bluetooth device from hardware list
🧯 If You Can't Patch
- Restrict administrative privileges within guest VMs to trusted users only
- Isolate vulnerable VMs from sensitive systems and implement network segmentation
🔍 How to Verify
Check if Vulnerable:
Check VMware version in Help > About. If Workstation is below 17.5.2 or Fusion below 13.5.2, the system is vulnerable.Check Version:
On Windows: wmic product get name,version | findstr VMware
On Linux/macOS: vmware --versionVerify Fix Applied:
Verify version shows 17.5.2 or higher for Workstation, 13.5.2 or higher for Fusion in Help > About.📡 Detection & Monitoring
Log Indicators:
- Unusual memory access patterns from VM processes
- Suspicious Bluetooth device operations in VM logs
Network Indicators:
- Unusual outbound data transfers from VMs to unexpected destinations
