VMware Workstation, Workstation Pro, and Fusion have been subjected to several privately reported and fixed flaws. VMware has published a security advisory on the critical bugs discovered and their workarounds.
The severity of these CVEs varies from 7.1 to 9.3. However, VMware has released a patch for all the affected versions.
CVSS Score: 9.3
To exploit this, a threat actor must have local admin privileges on the virtual machine. Exploitation leads to the execution of code using VMware’s VMX process on the host machine.
CVSS Score: 7.1
To exploit this, a threat actor must have local admin privileges on the virtual machine. Exploitation leads to the reading of privileged information on VMware’s hypervisor memory used for isolating virtual machines from each other. This memory includes CPU utilization, OS on the virtual machine, memory utilization, and much more.
CVSS Score: 7.3
To exploit this, a threat actor must have read/write access to the host machine. Exploitation leads to gaining root access to the host operating system.
CVSS Score: 7.1
To exploit this, a threat actor must have a virtual machine with a Physical CD/DVD drive attached and a SCSI controller configured with the host machine. Exploitation leads to the execution of code in VMware’s hypervisor memory from the virtual machine. The threat actor does not need local admin privilege for this vulnerability.
