- Fix
22.0.10- Upgrade org.keycloak:keycloak-services to this version or later
Description
Keycloak does not correctly validate its client step-up authentication. A password-authed attacker could use this flaw to register a false second auth factor, alongside the existing one, to a targeted account. The second factor then permits step-up authentication.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.keycloak:keycloak-services | < 22.0.10 |
22.0.10 |
| org.keycloak:keycloak-services | >= 23.0.0, < 24.0.3 |
24.0.3 |
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-287: Improper Authentication
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
How to prevent it
- Architecture and Design: Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CWE-288: Authentication Bypass Using an Alternate Path or Channel
The product requires authentication, but the product has an alternate path or channel that does not require authentication.
How to prevent it
- Architecture and Design: Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
