A vulnerability was found in Cisco SD-WAN Solution up to 18.2.x. It has been classified as critical. Affected is an unknown functionality of the component Zero Touch Provisioning. The manipulation as part of a Parameter leads to a command injection vulnerability. CWE is classifying the issue as CWE-77.
