Descriptions
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 prl_hypervisor kext. The issue results from the lack of proper validation of user-supplied data, which can result a pointer to be leaked after the handler is done. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. Was ZDI-CAN-10520.
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 kext prl_hypervisor. El problema resulta de una falta de comprobación apropiada de los datos suministrados por el usuario, lo que puede resultar en que un puntero sea filtrado una vez finalizado el manejador. Un atacante puede aprovechar esto en conjunto con otras vulnerabilidades para ejecutar código arbitrario en el contexto del kernel. Fue ZDI-CAN-10520
