      "value": "SAP MII allows users to create dashboards and save them as JSP through the SSCE (Self Service Composition Environment). An attacker can intercept a request to the server, inject malicious JSP code in the request and forward to server. When this dashboard is opened by users having at least SAP_XMII Developer role, malicious content in the dashboard gets executed, leading to remote code execution in the server, which allows privilege escalation. The malicious JSP code can contain certain OS commands, through which an attacker can read sensitive files in the server, modify files or even delete contents in the server thus compromising the confidentiality, integrity and availability of the server hosting the SAP MII application. Also, an attacker authenticated as a developer can use the application to upload and execute a file which will permit them to execute operating systems commands completely compromising the server hosting the application."

      "value": "SAP MII permite a los usuarios crear cuadros de mando y guardarlos como JSP a trav\u00e9s del SSCE (Self Service Composition Environment). Un atacante puede interceptar una petici\u00f3n al servidor, inyectar c\u00f3digo JSP malicioso en la petici\u00f3n y reenviarlo al servidor. Cuando este tablero es abierto por usuarios que tienen al menos el rol de Desarrollador SAP_XMII, el contenido malicioso en el tablero se ejecuta, llevando a la ejecuci\u00f3n remota de c\u00f3digo en el servidor, lo que permite la escalada de privilegios. El c\u00f3digo JSP malicioso puede contener ciertos comandos del sistema operativo, a trav\u00e9s de los cuales un atacante puede leer archivos sensibles en el servidor, modificar archivos o incluso eliminar contenidos en el servidor, comprometiendo as\u00ed la confidencialidad, integridad y disponibilidad del servidor que aloja la aplicaci\u00f3n SAP MII. Adem\u00e1s, un atacante autentificado como desarrollador puede utilizar la aplicaci\u00f3n para cargar y ejecutar un archivo que le permitir\u00e1 ejecutar comandos del sistema operativo comprometiendo completamente el servidor que aloja la aplicaci\u00f3n"
