Vulnerability Details : CVE-2022-34890
This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 17.1.1 (51537). An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Parallels Tools component. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-16653.
