Spring Social Facebook：“OAuth2'狀態'參數不匹配”

Question

我在Spring MVC項目中使用Spring Social Facebook來支持Facebook登錄。 這在幾乎所有情況下都運行良好，但偶爾我會在日志中看到以下異常。

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

我無法弄清楚這種情況何時發生，我無法重現它，但我已經看到它發生在其他用戶很多次。 以下是我的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;
    }
}

為什么會發生這種情況，我該怎么做才能防止這種情況發生？ 謝謝。

Answer 1

state參數可防止OAuth2中的CSRF攻擊。

這個想法是：

• 您的應用程序將state參數添加到它對身份驗證服務器（在本例中為Facebook）的請求中
• 身份驗證服務器在響應中將該state參數的確切值回送給您
• 然后檢查它們是否匹配

這聽起來毫無意義......但它可以防止攻擊者發出它未啟動的客戶端應用程序操作請求。

這非常詳細地介紹了它：

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

Spring Social為您處理所有這些：為每個請求生成一個新的隨機state ，並自動嘗試將其與響應中的值匹配。

所以你不能阻止它： ，你不想：這些可能是真正的失敗攻擊嘗試 - 在這種情況下，你希望發生這種錯誤。

對於您發布的案例， 可能只是由Spring Social或Facebook的身份驗證服務器對state參數進行錯誤處理。

但是，對於您而言，您應該處理異常，就好像它是真正的攻擊嘗試：記錄警告/警告人/等。

Answer 2

此函數只生成一個狀態值String（默認情況下為UUID.randomUUID().toString() ），將其置於會話中並作為授權請求中的“state”參數傳遞給提供者。 預計提供商會在回調時將其傳回。 如果存儲的狀態與回調中的狀態匹配，那么我們就是好的。 如果他們不匹配，那就是當你看到你在那里提到的例外時。

這應該是可行的，但是我看到你在這里遇到問題。 我還發現這個鏈接可能值得一看： https ： //github.com/spring-projects/spring-social-facebook/issues/103
