CVE-2022-21833 Virtual Machine IDE Drive Elevation of Privilege Vulnerability.
This issue is due to a race condition that can occur due to the way the virtual machine boots. In order to exploit this issue, a malicious user must be able to boot a virtual machine. This can be done by either gaining remote access to the system or by physically taking the disk out of the host. The disk must then be put into a virtual machine and the malicious code executed. The user must have administrator privileges in the virtual machine in order to exploit this issue.
Once the virtual machine is booted, a user can perform various operations. Most importantly, the user can change the drive letter of the virtual machine’s hard drive. If an attacker is able to gain administrator access to a virtual machine and can change the hard drive letter, then the attacker can install any file system to host malicious software on the system.
Vulnerability details
There has been an issue in the virtual machine boot process due to a race condition. When the virtual machine boots, it is possible that it can change the drive letter of its hard drive if an attacker gains administrator access.
A malicious user must be able to boot the virtual machine in order to exploit this issue. This can either be done by remote access or by physically taking the disk out of the host and putting it into a virtual machine. The disk must then be put into a virtual machine and malicious code executed. The user must have administrator privileges in the virtual machine in order to exploit this issue.
CVE-2022-21834
This issue is due to a race condition that can occur while the virtual machine boots. In order to exploit this issue, a malicious user must be able to boot a virtual machine. This can be done by either gaining remote access to the system or by physically taking the disk out of the host. The disk must then be put into a virtual machine and the malicious code executed. The user must have administrator privileges in the virtual machine in order to exploit this issue.
Once the virtual machine is booted, a user can perform various operations. Most importantly, the user can change the drive letter of the virtual machine’s hard drive. If an attacker is able to gain administrator access to a virtual machine and can change the hard drive letter, then they will be able to install any file system on their own file system.
VMWare Workstation
VMWare Workstation is a virtual machine manager that includes enterprise-class features such as live migration, high availability, and vMotion. This product is commonly used in the enterprise setting for testing and development. VMWare Workstation contains industry standard features that make it easy for enterprises to provision virtual machines quickly. It also allows for integration with other products like Active Directory, VMware ESX Hosts, Microsoft Exchange Server, Oracle Database, and others. With all of these features, VMWare Workstation makes it easy for companies to manage their virtual environments and test new software before rolling out into production.
The ability to migrate from one host to another at any time can be very beneficial due to the increased productivity from reduced downtimes associated with downtimes related to hardware failure. The ability to move a running VM without downtime allows companies more opportunities to save costs on maintenance, increase uptime and reduce downtime overall.
Vulnerability Details:
A race condition vulnerability exists in the way that virtual machines boot. In order to exploit this issue, a malicious user must have either physical access to the host system or remote control of the system. The user must then execute malicious code on the host system with administrator privileges in order to exploit this vulnerability.
Once installed, malicious software can perform various tasks including changing the drive letter of a virtual machine’s hard drive. This could allow a hacker to install any file system of their choice onto the host system.
