An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to overflow an internal buffer and execute arbitrary commands at the root privilege level."},{"lang":"es","value":"Múltiples vulnerabilidades en la interfaz de administración basada en web de los teléfonos IP Cisco Small Business serie SPA300 y los teléfonos IP Cisco Small Business serie SPA500 podrían permitir que un atacante remoto no autenticado ejecute comandos arbitrarios en el sistema operativo subyacente con privilegios de superusuario. Estas vulnerabilidades existen porque los paquetes HTTP entrantes no se verifican adecuadamente en busca de errores, lo que podría provocar un desbordamiento del búfer. Un atacante podría aprovechar esta vulnerabilidad enviando una solicitud HTTP diseñada a un dispositivo afectado.
