B107: hardcoded_password_default


B107: Test for use of hard-coded password argument defaults

The use of hard-coded passwords increases the possibility of password guessing tremendously. This plugin test looks for all function definitions that specify a default string literal for some argument. It checks that the argument does not look like a password.

Variables are considered to look like a password if they have match any one of:

  • “password”
  • “pass”
  • “passwd”
  • “pwd”
  • “secret”
  • “token”
  • “secrete”

Note: this can be noisy and may generate false positives.
