在SimpleSAMLphp中发现了一个签名验证 bypass 问题,问题始于1.14.16。使用SAML 1.1的SimpleSAMLphp服务供应商将包含多个签名的未加密SAML响应视为有效,只要至少一个签名有效。接收到的所有签名将合并,并使用接收到的第一个签名实体ID,使攻击者能够以任何IdP的任意用户身份对目标IdP发送 signed assertion。

漏洞描述信息
A signature-validation bypass issue was discovered in SimpleSAMLphp through 1.14.16. A SimpleSAMLphp Service Provider using SAML 1.1 will regard as valid any unsigned SAML response containing more than one signed assertion, provided that the signature of at least one of the assertions is valid. Attributes contained in all the assertions received will be merged and the entityID of the first assertion received will be used, allowing an attacker to impersonate any user of any IdP given an assertion signed by the targeted IdP.
