Summary
  • (es) Una vulnerabilidad en la interfaz de administración basada en web del firmware del teléfono IP de Cisco podría permitir que un atacante remoto no autenticado recupere información confidencial de un dispositivo afectado. Esta vulnerabilidad se debe a la falta de autenticación para endpoints específicos de la interfaz de administración basada en web en un dispositivo afectado. Un atacante podría aprovechar esta vulnerabilidad conectándose al dispositivo afectado. Un exploit exitoso podría permitir al atacante obtener acceso no autorizado al dispositivo, lo que permitiría registrar las credenciales del usuario y el tráfico hacia y desde el dispositivo afectado, incluidas las llamadas VoIP que podrían reproducirse.
