Weakness (CWE)

CWE-307: Improper Restriction of Excessive Authentication Attempts

Base Draft

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

How to prevent it (2 mitigations)

  1. Architecture and Design

    Common protection mechanisms include:

    - Disconnecting the user after a small number of failed attempts

    - Implementing a timeout

    - Locking out a targeted account

    - Requiring a computational task on the user's part.

  2. Architecture and Design

    Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].

    Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
