Upgrade org.keycloak:keycloak-services to this version or later

Description

If an attacker launches many login attempts in parallel then the attacker can have more guesses at a password than the brute force protection configuration permits. This is due to the brute force check occurring before the brute force protector has locked the user.

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness

CWE-307: Improper Restriction of Excessive Authentication Attempts

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

How to prevent it
  • 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]

CWE-837: Improper Enforcement of a Single, Unique Action

The product requires that an actor should only be able to perform an action once, or to have only one unique action, but the product does not enforce or improperly enforces this restriction.
