Description Preview
A vulnerability in Parallels Desktop Service allows local attackers with low-level privileges to escalate to root privileges. The issue stems from improper initialization of environment variables within the Parallels Service, enabling attackers to execute arbitrary code with root privileges on affected systems.
Overview
CVE-2023-27322 affects Parallels Desktop, a popular virtualization software for macOS. The vulnerability exists in the Parallels Service component, which runs with elevated privileges. Due to improper initialization of environment variables, an attacker who already has access to run low-privileged code on the target system can manipulate these variables to trigger a privilege escalation. This allows the execution of arbitrary code with root-level permissions, effectively compromising the entire system. This vulnerability was reported to the Zero Day Initiative as ZDI-CAN-17751 and was later published as advisory ZDI-23-216.
Remediation
Users of affected Parallels Desktop installations should:
- Update to the latest version of Parallels Desktop as provided by the vendor
- Apply any security patches released by Parallels specifically addressing this vulnerability
- Follow the guidance provided in the Parallels Knowledge Base article (KB125013)
- Implement the principle of least privilege for all user accounts with access to the system
- Monitor system logs for any suspicious activities that might indicate exploitation attempts
