Vulnerability from gsd

Details
A vulnerability in an API endpoint of multiple Cisco Unified Communications Products could allow an unauthenticated, remote attacker to cause high CPU utilization, which could impact access to the web-based management interface and cause delays with call processing. This API is not used for device management and is unlikely to be used in normal operations of the device.
This vulnerability is due to improper API authentication and incomplete validation of the API request. An attacker could exploit this vulnerability by sending a crafted HTTP request to a specific API on the device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition due to high CPU utilization, which could negatively impact user traffic and management access. When the attack stops, the device will recover without manual intervention.

"value": "Una vulnerabilidad en un endpoint de la API de m\u00faltiples productos de Comunicaciones Unificadas de Cisco podr\u00eda permitir que un atacante remoto no autenticado provoque una alta utilizaci\u00f3n de la CPU, lo que podr\u00eda afectar el acceso a la interfaz de administraci\u00f3n basada en web y causar retrasos en el procesamiento de llamadas. Esta API no se utiliza para la administraci\u00f3n de dispositivos y es poco probable que se utilice en las operaciones normales del dispositivo. Esta vulnerabilidad se debe a una autenticaci\u00f3n de API incorrecta y a una validaci\u00f3n incompleta de la solicitud. Un atacante podr\u00eda aprovechar esta vulnerabilidad enviando una solicitud HTTP manipulada a una API espec\u00edfica en el dispositivo. Un exploit exitoso podr\u00eda permitir que el atacante cause una condici\u00f3n de denegaci\u00f3n de servicio (DoS) debido a una alta utilizaci\u00f3n de la CPU, lo que podr\u00eda afectar negativamente al tr\u00e1fico de usuarios y al acceso de administraci\u00f3n.
