Weakness
CWE-640: Weak Password Recovery Mechanism for Forgotten Password
The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
How to prevent it
- Architecture and Design: Make sure that all input supplied by the user to the password recovery mechanism is thoroughly filtered and validated.
- Architecture and Design: Do not use standard weak security questions and use several security questions.
- Architecture and Design: Make sure that there is throttling on the number of incorrect answers to a security question. Disable the password recovery functionality after a certain (small) number of incorrect guesses.
- Architecture and Design: Require that the user properly answers the security question prior to resetting their password and sending the new password to the e-mail address of record.
- Architecture and Design: Never allow the user to control what e-mail address the new password will be sent to in the password recovery mechanism.
- Architecture and Design: Assign a new temporary password rather than revealing the original password.
