Descriptions

This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Access 6.5.3 (39313) Agent. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Dispatcher service. The service loads an OpenSSL configuration file from an unsecured location. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-15213.

Esta vulnerabilidad permite a atacantes locales escalar privilegios en las instalaciones afectadas de Parallels Access 6.5.3 (39313) Agent. Un atacante debe obtener primero la capacidad de ejecutar código poco privilegiado en el sistema de destino para poder explotar esta vulnerabilidad. El fallo específico se presenta en el servicio Dispatcher. El servicio carga un archivo de configuración OpenSSL desde una ubicación no segura. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto de SYSTEM. Era ZDI-CAN-15213
