com.atlassian.crowd.console.filter.LoginCsrfFilter

All Implemented Interfaces:

javax.servlet.Filter, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.context.EnvironmentAware, org.springframework.core.env.EnvironmentCapable, org.springframework.web.context.ServletContextAware

public class LoginCsrfFilter
extends org.springframework.web.filter.OncePerRequestFilter

Specialized filter to prevent CSRF attacks against the login url. Other pages should be protected by XsrfTokenInterceptor, which can't be used because because the login is handled by CrowdSSOAuthenticationProcessingFilter and interceptors are only applied after filters.
