An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected system. A successful exploit could allow the attacker to upload arbitrary files to the affected system. The malicious files could overwrite system files that are processed by the root system account and allow arbitrary command execution with root privileges. To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of video operator."}, {"lang": "es", "value": "Una vulnerabilidad en la funci\u00f3n de Gesti\u00f3n de Certificados de Cisco Meeting Management podr\u00eda permitir a un atacante remoto autenticado cargar archivos arbitrarios, ejecutar comandos arbitrarios y elevar privilegios a root en un sistema afectado.\n\nEsta vulnerabilidad se debe a una validaci\u00f3n de entrada incorrecta en ciertas secciones de la interfaz de gesti\u00f3n basada en web.
