VMware Patches Critical Vulnerability CVE-2024-38812: What You Need to Know

In an era where cybersecurity threats loom large, the recent security disclosure from VMware regarding a critical vulnerability in its vCenter Server has sent ripples through the IT community. This vulnerability, identified as CVE-2024-38812, poses a significant risk to organizations relying on VMware’s virtualized infrastructures. With the potential for Remote Code Execution (RCE) and full system compromise, it’s crucial for businesses to understand the implications and take immediate action.

CVE-2024-38812: A Critical Heap-Overflow Flaw

CVE-2024-38812 has been assigned a CVSS score of 9.8, categorizing it as critical. The vulnerability arises from a heap-overflow issue within the Distributed Computing Environment/Remote Procedure Call (DCERPC) protocol. This protocol is integral to distributed computing, a common necessity in enterprise environments. However, the flaw opens a dangerous attack vector that malicious actors could exploit.

An attacker with network access to the vCenter Server could send a specially crafted network packet, leading to RCE. This means that the attacker could potentially execute arbitrary code on the server, compromising the entire system. While there have been no confirmed instances of this vulnerability being exploited in the wild, the threat it poses is significant and warrants immediate attention.

VMware’s Response and Patching

VMware acted quickly to address this vulnerability, initially releasing patches on September 17, 2024. However, it soon became apparent that these patches did not fully mitigate the issue. On October 21, 2024, VMware issued an updated patch via the Broadcom Support page, which also included fixes for another vulnerability, CVE-2024-38813.

The affected products include VMware Cloud Foundation and VMware vCenter Server. Organizations are advised to apply the following patches based on their specific VMware product versions:

• VMware Cloud Foundation 4.x – Update to 7.0 U3t
• VMware Cloud Foundation 5.1.x – Update to 8.0 U2e
• VMware Cloud Foundation 5.x – Update to 8.0 U3d
• VMware vCenter Server 7.0 – Update to 7.0 U3t
• VMware vCenter Server 8.0 – Update to 8.0 U2e or 8.0 U3d

Despite investigating in-product workarounds, VMware concluded that no viable alternatives exist, making patching the only effective resolution.
