CVE-2023-50226

Enlace de Parallels Desktop Updater tras una vulnerabilidad de escalada de privilegios local. Esta vulnerabilidad permite a atacantes locales escalar privilegios en las instalaciones afectadas de Parallels Desktop. Un atacante primero debe obtener la capacidad de ejecutar código con pocos privilegios en el sistema host de destino para poder aprovechar esta vulnerabilidad. La falla específica existe dentro del servicio Updater. Al crear un enlace simbólico, un atacante puede abusar del servicio para mover archivos arbitrarios. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto de la raíz. Era ZDI-CAN-21227.

Parallels Desktop Updater Link Following 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 move arbitrary files. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.
