Descriptions
This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 15.1.4. 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 prl_hypervisor kext. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor. Was ZDI-CAN-11304.
Esta vulnerabilidad permite a atacantes locales escalar privilegios en las instalaciones afectadas de Parallels Desktop versión 15.1.4. 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 kext prl_hypervisor. El problema resulta de una falta de comprobación apropiada de los datos suministrados por el usuario, lo que puede resultar en una lectura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código en el contexto del hypervisor. Fue ZDI-CAN-11304
