Cualquier usuario que sea profesor en un curso (incluidos los cursos autocreados) puede mover documentos, haciendo que esta vulnerabilidad sea explotable por cualquier usuario autenticado. El atacante debe primero colocar un directorio con metacaracteres de shell en su nombre en el sistema de archivos (lograble a trav\u00e9s de la importaci\u00f3n de copia de seguridad del curso), luego mover un documento a ese directorio para desencadenar la ejecuci\u00f3n arbitraria de comandos como el usuario del servidor web (www-data).
