Source: CVE Program / CVE List V5
Vulnerability Description
Parallels Desktop Toolgate Directory Traversal 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 a user-supplied path prior to using it in file operations.
