Vulnerability Details
The vCenter Server contains a privilege escalation vulnerability. A malicious actor with network access to vCenter Server may trigger this vulnerability to escalate privileges to root by sending a specially crafted network packet. This vulnerability is classified under CWE-250 (Improper Check for Dropped Privileges) and CWE-273 (Improper Verification of Integrity).
The CVSS score for this vulnerability is 7.5, indicating a high severity. The vulnerability can be exploited over a network, requiring low privileges and no user interaction. The potential impacts on confidentiality, integrity, and availability are all rated as high.
Affected products include VMware vCenter Server versions 7.0 and 8.0, along with VMware Cloud Foundation. The publication date for this vulnerability is September 17, 2024.
Technical Analysis
The root cause of this vulnerability is an improper check for dropped privileges within the vCenter Server. The attack vector is network-based, which allows attackers to exploit it remotely without needing physical access to the system. The attack complexity is rated as high, requiring specific conditions to be met for successful exploitation.
Privileges required for exploitation are low, meaning that an attacker does not need elevated privileges to initiate the exploit. Furthermore, user interaction is not required, increasing the risk of exploitation. The impacts of a successful exploit include high confidentiality, integrity, and availability risks.
Risk & Impact Analysis
Organizations deploying VMware vCenter Server are at significant risk due to this vulnerability. If exploited, attackers could gain root access, allowing them to manipulate virtual machines, access sensitive data, and disrupt services.
The blast radius for this vulnerability could be extensive, potentially affecting all virtual machines managed by vCenter Server. Organizations must consider the implications of unauthorized access, including data breaches and service outages.
Based on the CVSS score and the inclusion in the KEV catalog, it is critical for organizations to prioritize remediation. The exploitability score further emphasizes the urgency of addressing this vulnerability.
