Descriptions

Macrium Reflect includes an OpenSSL component that specifies an OPENSSLDIR variable as C:\openssl\. Macrium Reflect contains a privileged service that uses this OpenSSL component. Because unprivileged Windows users can create subdirectories off of the system root, a user can create the appropriate path to a specially-crafted openssl.cnf file to achieve arbitrary code execution with SYSTEM privileges.

Macrium Reflect incluye un componente OpenSSL que especifica una variable OPENSSLDIR como C:\openssl\. Macrium Reflect contiene un servicio privilegiado que utiliza este componente OpenSSL. Debido a que los usuarios de Windows no privilegiados pueden crear subdirectorios fuera del sistema root, un usuario puede crear la ruta apropiada para que un archivo openssl.cnf especialmente diseñado logre una ejecución de código arbitraria con privilegios SYSTEM
