VMware Workstation and Fusion contain an information disclosure vulnerability in the Host Guest File Sharing (HGFS) functionality. A malicious actor with local administrative privileges on a virtual machine may be able to read privileged information contained in hypervisor memory from a virtual machine.
VMware Workstation y Fusion contienen una vulnerabilidad de divulgación de información en la funcionalidad Host Guest File Sharing (HGFS). Un actor malintencionado con privilegios administrativos locales en una máquina virtual puede leer información privilegiada contenida en la memoria del hipervisor desde una máquina virtual.
This vulnerability allows local attackers to disclose sensitive information on affected installations of VMware Workstation. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability.
The specific flaw exists within the hgfsVMCI_fileread function. The issue results from the lack of proper initialization of memory prior to accessing it.An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the hypervisor.
