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: "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.\r\n\r 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.",

Esta API no se utiliza para la administración de dispositivos y es poco probable que se utilice en las operaciones normales del dispositivo. Esta vulnerabilidad se debe a una autenticación de API incorrecta y a una validación incompleta de la solicitud. Un atacante podría aprovechar esta vulnerabilidad enviando una solicitud HTTP manipulada a una API específica en el dispositivo. Un exploit exitoso podría permitir que el atacante cause una condición de denegación de servicio (DoS) debido a una alta utilización de la CPU, lo que podría afectar negativamente al tráfico de usuarios y al acceso de administración.
