This vulnerability allows local attackers to disclose information on affected installations of Parallels Desktop 15.1.3-47255. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handler for HOST_IOCTL_INIT_HYPERVISOR in the prl_hypervisor kext. The issue results from the exposure of dangerous method or function to the unprivileged user. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. Was ZDI-CAN-10518.
Esta vulnerabilidad permite a atacantes locales revelar información sobre las instalaciones afectadas de Parallels Desktop versión 15.1.3-47255. Un atacante debe primero obtener la capacidad de ejecutar código poco privilegiado en el sistema objetivo para explotar esta vulnerabilidad. El fallo específico se presenta dentro del manejador de HOST_IOCTL_INIT_HYPERVISOR en el kext prl_hypervisor. El problema es el resultado de la exposición de un método o una función peligrosos para el usuario no privilegiado. Un atacante puede aprovechar esto en conjunto con otras vulnerabilidades para ejecutar código arbitrario en el contexto del kernel. Fue ZDI-CAN-10518
