Pattern: Use of hard-coded password function arguments

Issue: -

Description

The use of hard-coded passwords increases the possibility of password guessing tremendously. This rule looks for all function calls being passed a keyword argument that is a string literal. It checks that the assigned local variable 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.

Example of insecure code:

doLogin(password="1234")
