Spring Security-无法验证SAML证书

编程问答 2022-06-06

问题描述

我正在Spring Boot应用程序中使用org.springframework.security:spring-security-saml2-service-provider版的5.3.3.RELEASE和spring-boot-starter-security版的2.3.1.RELEASE来保护它。

出于测试目的，我将docker映像kristophjunge/test-saml-idp用作我的身份提供者。

从Maven，IntelliJ或只是它的主要方法执行应用程序时，身份验证可以正常工作。当我从中构建一个war文件并在本地计算机上的版本9的tomcat服务器中执行该应用程序时，身份验证工作正常。

如果将war文件部署到远程服务器，Ubuntu 20.04.1 LTS，相同的JDK，openjdk 14.0.1，相同的tomcat，相同的docker映像，相同的证书，则该证书无法被应用程序验证。 / p>

我已经为opensaml启用了调试日志。我的计算机上的成功身份验证如下：

[http-nio-8080-exec-3] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Signature validation using candidate credential was successful
[http-nio-8080-exec-3] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Successfully verified signature using KeyInfo-derived credential
[http-nio-8080-exec-3] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Attempting to establish trust of KeyInfo-derived credential
[http-nio-8080-exec-3] DEBUG org.opensaml.security.trust.impl.ExplicitKeyTrustEvaluator - Successfully validated untrusted credential against trusted key
[http-nio-8080-exec-3] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Successfully established trust of KeyInfo-derived credential

虽然远程服务器上的日志输出看起来像这样：

[http-nio-8080-exec-41] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Signature validation using candidate credential was successful
[http-nio-8080-exec-41] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Successfully verified signature using KeyInfo-derived credential
[http-nio-8080-exec-41] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Attempting to establish trust of KeyInfo-derived credential
[http-nio-8080-exec-41] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Failed to establish trust of KeyInfo-derived credential
[http-nio-8080-exec-41] DEBUG org.opensaml.xmlsec.signature.support.impl.BaseSignatureTrustEngine - Failed to verify signature and/or establish trust using any KeyInfo-derived credentials

我对自签名证书进行了修改，以为该错误将源于在非localhost域上访问的应用程序。我创建了一个根证书，将其添加到JDK的cacerts密钥库中，并从该证书派生IDP证书。重新启动tomcat，没有用。

但是，真正令人好奇的是：如果我将应用程序作为独立的jar文件运行，那么即使在远程服务器上，身份验证过程也可以工作。不幸的是，这对我来说不可行。我只能使用集成的tomcat服务器进行开发。

我已经使用Kotlin配置了这样的安全性：

@EnableWebSecurity
class SecurityConfig(/* autowired configuration properties */) {
    override fun configure(http: HttpSecurity) {
        http
            .authorizeRequests()
                .antMatchers("/error").permitAll()
                .anyRequest().authenticated()
            .and()
                .saml2Login()
                .relyingPartyRegistrationRepository(
                        InMemoryRelyingPartyRegistrationRepository(
                                relyingPartyRegistration()
                        ))
                .authenticationManager(DbBasedUserDetailsService(rightsRepository))
    }

    private fun relyingPartyRegistration(): RelyingPartyRegistration =
        RelyingPartyRegistration
            .withRegistrationId(registrationId)
            .providerDetails {
                it.entityId(entityId)
                it.webSsoUrl(webSsoUrl)
            }
            .assertionConsumerServiceUrlTemplate(assertionUrlTemplate)
            .credentials {
                it.add(
                    Saml2X509Credential(
                        x509Certificate(idpKey),Saml2X509Credential.Saml2X509CredentialType.VERIFICATION))
            }.credentials {
                it.add(
                    Saml2X509Credential(
                        privateKey(),x509Certificate(localCert),Saml2X509Credential.Saml2X509CredentialType.SIGNING))
            }
            .build()

    private fun privateKey(): PrivateKey =
        KeyFactory
            .getInstance("RSA")
            .generatePrivate(PKCS8EncodedKeySpec(privateKey.inputStream.readBytes()))

    private fun x509Certificate(res: Resource) =
        CertificateFactory
            .getInstance("X.509")
            .generateCertificate(res.inputStream)
            as X509Certificate
}

它基本上类似于javadoc示例。

有人对我有线索吗？
