java - Spring 社交 Facebook : "The OAuth2 ' state' parameter doesn't match"

Question

我在 Spring MVC 项目中使用 Spring Social Facebook 来支持 Facebook 登录。这在几乎所有情况下都运行良好，但偶尔我会在日志中看到以下异常。

ERROR org.springframework.social.connect.web.ProviderSignInController - Exception while completing OAuth 2 connection:

我无法弄清楚这种情况何时发生，也无法重现，但我已经多次看到其他用户发生这种情况。下面是我的 Spring Social Facebook 配置。

@Configuration
public class SocialConfig {
    @Bean
    public ProviderSignInController providerSignInController() {
        ProviderSignInController controller = new ProviderSignInController(this.connectionFactoryLocator(), this.usersConnectionRepository(), new SpringSecuritySignInAdapter(this.accountRepository));
        controller.addSignInInterceptor(new RedirectToPreviousPageInterceptor(controller, this.analyticsService));

        return controller;
    }

    @Bean
    public ConnectionFactoryRegistry connectionFactoryLocator() {
        ConnectionFactoryRegistry connectionFactoryRegistry = new ConnectionFactoryRegistry();
        List<ConnectionFactory<?>> connectionFactories = new ArrayList<ConnectionFactory<?>>();
        connectionFactories.add(this.facebookConnectionFactory());
        connectionFactoryRegistry.setConnectionFactories(connectionFactories);

        return connectionFactoryRegistry;
    }

    @Bean
    public FacebookConnectionFactory facebookConnectionFactory() {
        FacebookConnectionFactory connectionFactory = new FacebookConnectionFactory(this.facebookAppId, this.facebookAppSecret);
        connectionFactory.setScope(this.scope);

        return connectionFactory;
    }

    @Bean
    @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
    public Facebook facebook(ConnectionRepository repository) {
        Connection<Facebook> connection = repository.findPrimaryConnection(Facebook.class);
        return (connection != null ? connection.getApi() : null);
    }

    @Bean
    @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
    public ConnectionRepository connectionRepository() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

        if (authentication == null) {
            throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
        }

        Account account = (Account) authentication.getPrincipal();
        return this.usersConnectionRepository().createConnectionRepository(String.valueOf(account.getId()));
    }

    @Bean
    public JdbcUsersConnectionRepository usersConnectionRepository() {
        JdbcUsersConnectionRepository repository = new JdbcUsersConnectionRepository(this.dataSource, this.connectionFactoryLocator(), this.textEncryptor);
        repository.setConnectionSignUp(this.accountService);

        return repository;
    }
}

为什么会发生这种情况，我该怎么做才能防止这种情况发生？谢谢。

Answer 1

state 参数防止 OAuth2 中的 CSRF 攻击。

想法是:

• 您的应用将 state 参数添加到它向身份验证服务器(在本例中为 Facebook)发出的请求
• 身份验证服务器在响应中将state 参数的确切值返回给您
• 然后检查它们是否匹配

这听起来毫无意义......但它可以防止攻击者发出您的客户端应用程序操作请求，但它并未发起。

这涵盖了非常详细的内容:

http://www.twobotechnologies.com/blog/2014/02/importance-of-state-in-oauth2.html

Spring Social 为您处理所有这一切:为每个请求生成一个新的随机 state，并自动尝试将其与响应中的值相匹配。

所以您无法阻止它:，并且您不想:这些可能是真正失败的攻击尝试 - 在那些情况下，您想要这个发生错误。

对于您发布的案例，可能只是 Spring Social 或 Facebook 的身份验证服务器对 state 参数的错误处理。

但是，就您而言，您应该像处理真正的攻击尝试一样处理异常:记录警告/提醒人们等。
