Parallels Desktop Toolgate XML Injection 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 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 string before using it to construct an XML document. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-19187.
Vulnerabilidad de escalada de privilegios locales de inyección XML de Parallels Desktop Toolgate. 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 invitado de destino para poder aprovechar esta vulnerabilidad. La falla específica existe dentro del componente Toolgate. El problema se debe a la falta de validación adecuada de una cadena proporcionada por el usuario antes de usarla para construir un documento XML. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto del hipervisor. Era ZDI-CAN-19187.
