Scenario: "Campina Grande": Give me my cert, Vault

Level: Medium

Type: Fix

Access: Email

Description: A web application running at https://nginx.example.com has an expired certificate. Issue a new certificate using the Hashicorp Vault running on the server.
The Vault instance is already unsealed and initialized, and you have full admin access with the admin user.

Test: Running curl https://nginx.example.com returns Hello!.

The certificate presented by Nginx is issued by the Vault PKI (check using openssl verify -CAfile /usr/local/share/ca-certificates/vault-pki-ca.crt /etc/nginx/ssl/cert.pem).

The "Check My Solution" button runs the script /home/admin/agent/check.sh, which you can see and execute.

Time to Solve: 15 minutes.
