VMware Tools for Windows versions 11.x.y and 10.x.y prior to 12.0.0 contain an uncontrolled search path vulnerability. This vulnerability allows a malicious actor with local administrative privileges in the Windows guest operating system, where VMware Tools is installed, to execute code with system privileges in the Windows guest OS due to the presence of an uncontrolled search path element.
The severity of this vulnerability is classified as medium, with a CVSS score of 6.7. This classification indicates that while the vulnerability is not the highest severity level, it still poses a significant risk. Organizations that utilize VMware Tools should be particularly vigilant, as the potential impact on systems can be substantial.
Risk to organizations includes potential unauthorized code execution, which could compromise sensitive data and system integrity. Given that local administrative privileges are required to exploit this vulnerability, the real-world risk is nuanced but still critical enough to address promptly.
As of now, no public exploit has been confirmed for this vulnerability, and it has not been reported in the Known Exploited Vulnerabilities (KEV) list. However, organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability allows local privilege escalation due to an uncontrolled search path element in VMware Tools for Windows. It affects versions 11.x.y and 10.x.y prior to 12.0.0. The CVSS score of 6.7 indicates a medium severity, reflecting potential impacts on confidentiality, integrity, and availability.
Published on March 3, 2022, this vulnerability is classified under CWE-427, which signifies that the software does not appropriately control the search path when loading external libraries.
Technical Analysis
The root cause of this vulnerability is the uncontrolled search path, which allows for exploitation when a malicious actor has local administrative privileges. The attack vector is local, meaning that the attacker must have access to the system where VMware Tools is installed.
The attack complexity is low, as it requires high privileges with no user interaction. The confidentiality, integrity, and availability impacts are all rated as high, underscoring the seriousness of the potential exploit.
Risk & Impact Analysis
Real-world deployment risk associated with this vulnerability stems from the potential for unauthorized code execution within the Windows guest OS. Organizations should consider the blast radius potential, particularly in environments where VMware Tools is widely deployed.
Given the CVSS score of 6.7, organizations should address this vulnerability in their priority patch cycle. The lack of known exploitation currently does not reduce the urgency of remediation, as the nature of the vulnerability could lead to significant impacts if exploited.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
Affected products include VMware Tools for Windows, specifically versions 11.x.y and 10.x.y prior to 12.0.0. Organizations not on the latest version are at risk.
Mitigation & Remediation
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The recommended action is to upgrade to VMware Tools version 12.0.0 or later. If immediate patching is not possible, consider implementing network controls to limit access to affected systems and monitor for any unusual activities that may indicate exploitation attempts.
For further guidance on remediation and best practices, organizations may refer to resources on penetration testing and application security assessments.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for any unauthorized attempts to execute code or modify system files within the Windows guest OS. Behavioral anomalies indicating privilege escalation attempts should also be closely examined.
AppSecure Threat Intelligence Insight
