Descriptions
This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 15.1.2-47123. 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 IOCTL handler. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. Was ZDI-CAN-10028.
Esta vulnerabilidad permite a atacantes locales escalar privilegios sobre las instalaciones afectadas de Parallels Desktop versión 15.1.2-47123. Un atacante primero debe obtener la capacidad de ejecutar código poco privilegiado sobre el sistema objetivo a fin de explotar esta vulnerabilidad. El fallo específico se presenta dentro del manejador de IOCTL. El problema resulta de la falta de una comprobación apropiada de los datos suministrados por el usuario, lo que puede resultar en una escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código en el contexto del kernel. Fue ZDI-CAN-10028.
