CloudBees CD/RO self-signed server certificate fails security scan

Description

You might need to replace the self-signed CloudBees CD/RO server certificate if it fails the security scan.

If you are using a certificate authority (CA) certificate or an intermediate CA certificate instead and it has expired, see CA Server Certificate Expires for details about updating it.

There are three relevant configuration entries in the server/conf/commander.properties file:

COMMANDER_HTTPS_PORT=8443
COMMANDER_KEYSTORE=file:conf/keystore
COMMANDER_KEYSTORE_PASSWORD=abcdef▼

Where:

COMMANDER_HTTPS_PORT configures the SSL port
COMMANDER_KEYSTORE is the location of the java keystore where the CloudBees CD/RO HTTP server finds its host certificate
COMMANDER_KEYSTORE_PASSWORD is the password to the keystore

Workaround

Follow these steps to generate and inject a self-signed certificate for 1 year.

Back up the keystore file.

Delete the original key.

user@USER /cygdrive/c/ProgramData/cloudbees/sda/conf
$ "c:/Program Files/cloudbees/sda/jre/bin/keytool" -delete -alias jetty -keystore keystore -keypass passkey
Enter keystore password: abcdef▼

Generate and inject a new certificate.

user@USER /cygdrive/c/ProgramData/cloudbees/sda/conf
$ "c:/Program Files/cloudbees/sda/jre/bin/keytool" -keystore keystore -alias jetty -genkey -keyalg RSA -sigalg MD5withRSA -validity 365
Enter keystore password: abcdef

. Restart the server.▼

Your new certificate will look similar to this:

user@USER /cygdrive/c/ProgramData/cloudbees/sda/conf
$ "c:/Program Files/cloudbees/sda/jre/bin/keytool" -list -v -keystore keystore_orig -keypass passkey
Enter keystore password: abcdef
