CVE-2024-37081 is a high-severity vulnerability affecting VMware vCenter Server due to multiple local privilege escalation vulnerabilities stemming from misconfiguration of sudo. An attacker with authenticated local user access and non-administrative privileges can exploit these vulnerabilities to gain elevated privileges to root on the vCenter Server Appliance.
The CVSS score for this vulnerability is 7.8, indicating a high level of severity that necessitates immediate attention from security teams. The existence of a known exploit amplifies the urgency for organizations to address this vulnerability proactively.
Risk to organizations includes unauthorized access to sensitive configurations and potential control over the vCenter Server environment, which could lead to broader network compromises. Given the critical role of vCenter Server in managing VMware environments, the implications of this vulnerability can be severe.
Organizations should prioritize patching immediately. Failure to address this vulnerability exposes systems to significant risks, especially in environments where VMware solutions are integral to operations.
Vulnerability Details
The vulnerability described is due to a misconfiguration in the sudo settings of the vCenter Server. This misconfiguration allows authenticated users to execute commands with elevated privileges, potentially leading to unauthorized access to sensitive data and configurations.
The vulnerability has been classified under CWE-556, which targets improper handling of privilege levels. This misconfiguration can be exploited by users who have non-administrative access, making it critical for organizations to assess their user management practices.
The CVSS vector for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, reflecting a local attack vector, low complexity, and high impact on confidentiality, integrity, and availability.
The vulnerability was published on June 18, 2024, and affects multiple versions of vCenter Server, including version 8.0 and 7.0.
Technical Analysis
The root cause of CVE-2024-37081 is the misconfiguration of the sudo command within the vCenter Server environment. This allows local authenticated users to execute commands with elevated privileges, effectively granting them root access.
The attack vector is local, meaning that an attacker must have some level of access to the system. The attack complexity is low, as the misconfiguration allows for straightforward exploitation without requiring advanced techniques. Privileges required for the attack are low, as attackers only need non-administrative access.
User interaction is not required, allowing an attacker to exploit the vulnerability autonomously. The impacts on confidentiality, integrity, and availability are all rated as high, indicating significant potential damage from a successful exploit.
Risk & Impact Analysis
Organizations deploying VMware vCenter Server should assess their exposure to this vulnerability carefully. The misconfiguration allows for unauthorized privilege escalation, which can lead to complete control over the vCenter environment. Such access could result in the manipulation of virtual machines, data breaches, and disruption of services.
Given the critical nature of vCenter Server in managing VMware infrastructures, the blast radius of this vulnerability is extensive. Attackers may leverage this vulnerability to not only compromise the immediate system but also pivot to other connected systems within the network.
With a CVSS score of 7.8, this vulnerability falls into the high-severity category, necessitating immediate action from organizations to mitigate potential risks. The lack of a known exploit history does not diminish the urgency, as the potential for exploitation is significant.
Organizations should address this vulnerability in their priority patch cycle to prevent exploitation and protect their environments.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of vCenter Server include 7.0 and 8.0, along with their respective updates. Organizations running these versions should prioritize remediation to mitigate the risks associated with this vulnerability.
Mitigation & Remediation
Organizations should apply the latest patches provided by VMware to remediate this vulnerability. If patches are unavailable, consider applying workarounds such as restricting user privileges and reviewing sudo configurations to prevent unauthorized privilege escalation.
Monitoring logs for unauthorized access attempts and implementing network controls can also help mitigate risks. For comprehensive validation of security measures, organizations should engage in penetration testing to ensure that all remediation efforts are effective.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor for log indicators such as failed sudo attempts, unusual user activity, and unauthorized access to sensitive areas of the vCenter environment.
Behavioral anomalies, such as unexpected command executions by non-administrative users, should also be investigated. Implementing network signatures to detect unauthorized access patterns can further enhance security posture.
AppSecure Threat Intelligence Insight
This vulnerability represents a significant risk for organizations relying on VMware vCenter Server for managing their virtual environments. As the trend of privilege escalation vulnerabilities continues to rise, security teams must remain vigilant in applying best practices for access control and configuration management.
To bolster defenses, organizations should review their incident response plans and ensure that they are prepared to respond to potential exploitation attempts. For best practices on vulnerability management, organizations can refer to the vulnerability management program and implement a robust security framework.
Security teams should also consider engaging in penetration testing methodology to validate their environment's security posture against similar vulnerabilities.
Ultimately, proactive measures are essential to mitigating risks associated with privilege escalation vulnerabilities like CVE-2024-37081.
