Parallels Desktop Toolgate Directory Traversal Local Privilege Escalation Vulnerability

CVE-2023-27326

What is CVE-2023-27326?

The vulnerability in the Toolgate component of Parallels Desktop allows local attackers to escalate their privileges on the affected installations. This issue arises due to insufficient validation of user-supplied paths, which are used in file operations. An attacker who has already gained the ability to execute high-privileged code on the target guest system can leverage this vulnerability to execute arbitrary code within the context of the current user on the host system. The implications of this vulnerability highlight the necessity for enhanced security practices around user input validation in file handling operations.
