Official description

The Build App Online plugin for WordPress is vulnerable to account takeover due to a weak password reset mechanism in all versions up to, and including, 1.0.22. This makes it possible for unauthenticated attackers to reset the password of arbitrary users by guessing an 4-digit numeric reset code.

The underlying weakness: 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 developers prevent this class of flaw

  • Make sure that all input supplied by the user to the password recovery mechanism is thoroughly filtered and validated.
  • Do not use standard weak security questions and use several security questions.
  • 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.
