The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a serious security flaw in Broadcom VMware vCenter Server to its Known Exploited Vulnerabilities catalog on Friday, noting it was actively being exploited despite a patch released in June 2024.
CVE-2024-37079 (CVSS score: 9.8) is a vulnerability related to a heap overflow in the DCE/RPC protocol, enabling attackers with network access to vCenter Server to execute remote code by sending a crafted network packet.

Broadcom fixed issues in June 2024, including CVE-2024-37080, a heap overflow in the DCE/RPC protocol that could allow remote code execution. Researchers Hao Zheng and Zibo Li from QiAnXin LegendSec reported these vulnerabilities.
During a presentation at the Black Hat Asia conference in April 2025, researchers revealed two flaws in the DCE/RPC service, part of four vulnerabilities that include three heap overflows and one privilege escalation. Broadcom patched the other two flaws, CVE-2024-38812 and CVE-2024-38813, in September 2024.
They discovered that a heap overflow vulnerability can be combined with the privilege escalation vulnerability (CVE-2024-38813) to gain unauthorized remote root access to ESXi.
It’s currently not known how CVE-2024-37079 is being exploited, if it’s the work of any known threat actor or group, or the scale of such attacks. However, Broadcom has since updated its advisory to officially confirm in-the-wild abuse of the vulnerability.
“Broadcom has information to suggest that exploitation of CVE-2024-37079 has occurred in the wild,” the company said in its update.
In light of active exploitation, Federal Civilian Executive Branch (FCEB) agencies are required to update to the latest version by February 13, 2026, for optimal protection.
