CWE-307: Improper Restriction of Excessive Authentication Attempts

MITRE CWE weakness

Description

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

Common consequences

• Access Control: Bypass Protection Mechanism

Mitigations

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.

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]
