CVE-2024-22274
📋 TL;DR
CVE-2024-22274 is an authenticated remote code execution vulnerability in VMware vCenter Server. Attackers with administrative shell access on the vCenter appliance can execute arbitrary commands on the underlying operating system. This affects organizations running vulnerable vCenter Server versions.
💻 Affected Systems
- VMware vCenter Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the vCenter Server with attacker gaining full control over the underlying operating system, potentially leading to lateral movement across the virtual infrastructure, data exfiltration, or ransomware deployment.
Likely Case
Privilege escalation from vCenter administrative access to full OS control, enabling persistence, credential harvesting, and manipulation of virtual machines and hosts.
If Mitigated
Limited impact if proper access controls, network segmentation, and monitoring are in place to detect and prevent unauthorized administrative access.
🎯 Exploit Status
Exploitation requires authenticated administrative access to the vCenter appliance shell, making it accessible to insiders or attackers who have compromised such credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/24308
Restart Required: Yes
Instructions:
1. Review the vendor advisory for affected versions and patches. 2. Apply the recommended patch from VMware. 3. Restart the vCenter Server as required. 4. Verify the patch is applied successfully.
🔧 Temporary Workarounds
Restrict Administrative Access
allLimit shell access to vCenter Server to only trusted administrators using strict access controls and monitoring.
Network Segmentation
allIsolate vCenter Server management interfaces from untrusted networks to reduce attack surface.
🧯 If You Can't Patch
- Implement strict access controls to limit who has administrative shell privileges on vCenter.
- Enhance monitoring and logging of administrative activities on vCenter Server for early detection of misuse.
🔍 How to Verify
Check if Vulnerable:
Check the vCenter Server version against the vendor advisory to see if it falls within affected ranges.Check Version:
From vCenter appliance shell: cat /etc/vmware-release or use vSphere Client to check version in the UI.Verify Fix Applied:
Verify that the patched version is installed and no unauthorized administrative shell access has occurred post-patch.📡 Detection & Monitoring
Log Indicators:
- Unusual shell access logs, unexpected command executions from administrative accounts on vCenter Server.
Network Indicators:
- Suspicious network traffic from vCenter Server management interfaces to external systems.
SIEM Query:
Example: search for 'shell access' or 'command execution' events from vCenter Server logs with administrative accounts.
