Descriptions

On Windows endpoints, the SecureConnector agent must run under the local SYSTEM account or another administrator account in order to enable full functionality of the agent. The typical configuration is for the agent to run as a Windows service under the local SYSTEM account. The SecureConnector agent runs various plugin scripts and executables on the endpoint in order to gather and report information about the host to the CounterACT management appliance. The SecureConnector agent downloads these scripts and executables as needed from the CounterACT management appliance and runs them on the endpoint. The SecureConnector agent fails to set any permissions on downloaded file objects. This allows a malicious user to take ownership of any of these files and make modifications to it, regardless of where the files are saved. These files are then executed under SYSTEM privileges. A malicious unprivileged user can overwrite these executable files with malicious code before the SecureConnector agent executes them, causing the malicious code to be run under the SYSTEM account.

En los endpoints de Windows, el agente SecureConnector debe ejecutarse bajo la cuenta SYSTEM local u otra cuenta de administrador para habilitar la funcionalidad total del agente. La configuración típica es para que el agente se ejecute como servicio de Windows bajo la cuenta SYSTEM local. El agente SecureConnector ejecuta varios scripts de plugin y ejecutables en el endpoint para recopilar y reportar información sobre el host en la aplicación de gestión de CounterACT. El agente SecureConnector descarga estos scripts y ejecutables cuando los necesita de la aplicación de gestión de CounterACT y los ejecuta en el endpoint. El agente SecureConnector no establece permisos en los objetos de archivo descargados. Esto permite que un usuario malicioso asuma la propiedad de cualquiera de estos archivos y los modifique, independientemente de dónde se guardan los archivos. Estos archivos se ejecutan después bajo privilegios SYSTEM. Un usuario malicioso no privilegiado puede sobrescribir estos archivos ejecutables con código malicioso antes de que los ejecute el agente SecureConnector, lo que provoca que el código malicioso se ejecute bajo la cuenta SYSTEM.
