The vCenter Server contains a server-side request forgery (SSRF) vulnerability. A malicious actor with network access to 443 on the vCenter Server may exploit this issue by accessing a URL request outside of vCenter Server or accessing an internal service. This vulnerability allows attackers to potentially gain unauthorized access to sensitive internal services, posing a significant risk to organizations.
With a CVSS score of 7.5, classified as high severity, organizations must recognize the potential risks associated with this vulnerability. The attack vector is network-based, and it has low complexity, meaning that a successful exploitation can be achieved without significant technical barriers. As a result, organizations should prioritize patching immediately.
The urgency for defenders is underscored by the fact that this vulnerability exposes critical internal services to potential exploitation. Organizations operating affected versions of VMware vCenter Server should take immediate action to mitigate this risk.
Currently, there are no known exploits in the wild for this vulnerability, but the potential for exploitation exists, and organizations should remain vigilant.
Vulnerability Details
The vCenter Server's SSRF vulnerability allows attackers to craft requests that can reach unauthorized internal services. This can lead to exposure of sensitive data or further internal system compromises. The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, indicating high confidentiality impact with no integrity or availability impact. Affected products include VMware vCenter Server versions 6.5, 6.7, and 7.0, along with VMware Cloud Foundation versions 3.0 to 4.3.1.
Technical Analysis
The root cause of this vulnerability lies in the server's handling of requests. The ability to send requests to internal services without proper validation can be exploited by attackers on the network. The attack vector is network-based, meaning that an attacker needs to have network access to the vCenter Server's port 443. The attack complexity is low, with no privileges or user interaction required for exploitation.
The confidentiality impact is high, as attackers can potentially access sensitive data through unauthorized internal services. However, there is no impact on integrity or availability, meaning that the exploitation does not modify or disrupt services directly.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive internal services, which can lead to data breaches or further system compromises. The blast radius of this vulnerability is significant due to the potential access to various internal systems connected to the vCenter Server. Given the high CVSS score and the potential for exploitation, organizations should address this vulnerability in their priority patch cycle.
Organizations should prioritize remediation efforts based on their deployment risk, ensuring that all affected systems are patched promptly. The urgency for addressing this vulnerability is high due to the implications for internal security.

Affected Versions
The following versions of VMware products are affected by this vulnerability: VMware vCenter Server versions 6.5, 6.7, and 7.0, as well as VMware Cloud Foundation versions 3.0 to 4.3.1. Organizations running these versions should ensure they are updated to the latest patched versions as soon as possible.
Mitigation & Remediation
Organizations should prioritize patching affected VMware products to mitigate the risks associated with this vulnerability. The latest patches can be found on the VMware security advisory page. If immediate patching is not feasible, consider implementing network segmentation to limit access to affected services and monitor for unusual traffic patterns.
For more comprehensive protection, organizations can implement penetration testing to identify vulnerabilities in their systems.
Detection Guidance
Organizations should monitor logs for any unusual access attempts to internal services that are not typically accessed by users. Behavioral anomalies may indicate an attempt to exploit the SSRF vulnerability. Additionally, network signatures should be established to detect potential exploitation attempts.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability lies in its potential for exploitation in complex environments where vCenter is deployed. Security teams need to remain vigilant and proactive in their defensive measures against such vulnerabilities. It is crucial to conduct regular security assessments and keep abreast of the latest threat intelligence.
For organizations looking to enhance their security posture, leveraging resources such as the penetration testing methodology can provide valuable insights for identifying and mitigating vulnerabilities.
Additionally, understanding the trends in vulnerability management can aid in prioritizing remediation efforts effectively.
