CVE-2021-31429: Parallels Desktop IDE Heap-based Buffer Overflow Privilege Escalation Vulnerability

First published: Thu Apr 29 2021(Updated: )

This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 15.1.5-47309. 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 IDE virtual device. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-13187.
