CVE-2022-34901

Estado: ModificadaAlta (7.8)—

This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Access 6.5.4 (39316) Agent. 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 Parallels Service. The service executes files from an unsecured location. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-16137.
