CVE-2024-6154: parallels desktop Heap Overflow (CVSS 6.7)

Description

Parallels Desktop Toolgate Heap-based Buffer Overflow Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop. 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 Toolgate component. 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 current user on the host system. Was ZDI-CAN-20450.
