CVE-2024-37085
Published: July 30, 2024
Official Description
VMware ESXi contains an authentication bypass vulnerability.

CISA KEV Advisory
VMware ESXi Authentication Bypass Vulnerability
VMware ESXi contains an authentication bypass vulnerability. A malicious actor with sufficient Active Directory (AD) permissions can gain full access to an ESXi host that was previously configured to use AD for user management by re-creating the configured AD group ('ESXi Admins' by default) after it was deleted from AD.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
This VMware ESXi vulnerability allows an attacker with specific Active Directory permissions to bypass authentication and gain full access to an ESXi host. The high EPSS score of 0.72474 suggests a high probability of exploitation, and its inclusion in the KEV catalog confirms it has been actively exploited.
This vulnerability has been actively exploited in the wild, as indicated by its presence in the KEV catalog. Attackers are leveraging this flaw to gain unauthorized access to ESXi hosts.
Review and secure Active Directory permissions, especially those related to ESXi user management. Ensure that ESXi hosts are updated with the latest security patches from VMware.
Technical Analysis
CVE-2024-37085 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2024-37085 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
