CWE
  • CWE-732 - Incorrect Permission Assignment for Critical Resource
Summary
This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 15.1.4 (47270). 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. By examining a log file, an attacker can disclose a memory address. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute code in the context of the kernel. Was ZDI-CAN-11063.
