Insecure service configuration - Key pair

Description​

The credentials to access the Key pair are the same to access the Keystore, good practices with respect to containers recommend that they are different because in case one is compromised not both are compromised keytool -genkey, -keyalg RSA, -alias opkeystore, -keypass Kpassword, -keystore opkeystore.jks, -storepass Spassword, - validity 365. The Kpassword must be different from the Spassword.

Impact​

Compromise the access to the files if the keys of the keystore are the same as those of the key pair.

Recommendation​

Implement best practices in cryptographic systems Recommendation for Cryptographic Key Generation.

Threat​

Anonymous attacker in adjacent network.

Expected Remediation Time​

⌚ 60 minutes.

Compliant code​

Every sensitive resource has a secure key pair configuration

jarsigner -keystore "enc_password" -certchain "bundle.pem" -tsa "http://time.certum.pl" -storetype PKCS11
  -providerClass sun.security.pkcs11.SunPKCS11 -providerArg "provider.cfg" -keypass "enc_password1"
  -storepass "enc_password2" "[your_code].jar" "[your_alias]"

Non compliant code​

There are shared key pairs for several sensitive resources

jarsigner -keystore "password1" -certchain "bundle.pem" -tsa "http://time.certum.pl" -storetype PKCS11
  -providerClass sun.security.pkcs11.SunPKCS11 -providerArg "provider.cfg" -keypass "password1"
  -storepass "password1" "[your_code].jar" "[your_alias]"
