Descriptions

A vulnerability in the Cisco SD-WAN Solution could allow an unauthenticated, remote attacker to bypass certificate validation on an affected device. The vulnerability is due to improper certificate validation. An attacker could exploit this vulnerability by supplying a system image signed with a crafted certificate to an affected device, bypassing the certificate validation. An exploit could allow an attacker to deploy a crafted system image.
