Title

Parallels Desktop Updater Time-Of-Check Time-Of-Use Local Privilege Escalation Vulnerability

Summary

Parallels Desktop Updater Time-Of-Check Time-Of-Use 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 low-privileged code on the target host system in order to exploit this vulnerability. The specific flaw exists within the Updater service. By creating a symbolic link, an attacker can abuse the service to execute a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. . Was ZDI-CAN-18150.
