Insecure service configuration - Keys

Description​

The source code repository stores cipher keys directly. Allowing an attacker with access to the source code to compromise the keys to impersonate the application or decrypt the communications between server and client.

Impact​

Obtain cypher keys to craft new attack vectors.

Recommendation​

Store the cipher keys in a secured Keystore.

Threat​

Authenticated attacker from Internet with access to the source code.

Expected Remediation Time​

⌚ 30 minutes.

Score​

Default score using CVSS 3.1. It may change depending on the context of the vulnerability.

Base​

Code Examples​

Compliant code​

Cipher keys are safely used as encrypted secrets in the code

public class DemoApplication {
  public static void main(String[] args) {
    decryptPass(password, secretKey);
  }
}

Non compliant code​

Cipher key directly stored on the source code

public class DemoApplication {
  cipherKey = "PlainKEY"
  public static void main(String[] args) {
    decryptPass(password, cipherKey);
  }
}
