Descriptions

A vulnerability in the Zero Touch Provisioning feature of the Cisco SD-WAN Solution could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data by using an invalid certificate. The vulnerability is due to insufficient certificate validation by the affected software. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt confidential information on user connections to the affected software.

Una vulnerabilidad en la característica Zero Touch Provisioning de Cisco SD-WAN Solution podría permitir que un atacante remoto no autenticado obtenga acceso no autorizado a datos sensibles utilizando un certificado no válido. Esta vulnerabilidad también se debe a la validación insuficiente de certificados por parte del software afectado. Un atacante podría explotar esta vulnerabilidad enviando un certificado manipulado a un dispositivo afectado. Una explotación exitosa podría permitir a un atacante realizar ataques Man-in-the-Middle (MitM) para descifrar información confidencial en las conexiones del usuario al software afectado.
