Title

SimpleSAMLphp密钥混淆漏洞

Description

SimpleSAMLphp是一套实现了SAML 2.0服务提供者和标识提供者功能的PHP身份验证应用程序。SAML2 library是其中的一个安全声明标记语言库。XmlSecLibs library是其中的一个XML安全库。 SimpleSAMLphp 1.15.3之前版本的SAML2库中使用的XmlSecLibs库存在安全漏洞，该漏洞源于程序未能正确的验证SAML断言签名。远程攻击者可通过构造特制的SAML断言利用该漏洞冒充用户。

CVE-2018-7644 (GCVE-0-2018-7644)

Vulnerability from cvelistv5 – Published: 2018-03-05 14:00 – Updated: 2024-08-05 06:31

Summary

The XmlSecLibs library as used in the saml2 library in SimpleSAMLphp before 1.15.3 incorrectly verifies signatures on SAML assertions, allowing a remote attacker to construct a crafted SAML assertion on behalf of an Identity Provider that would pass as cryptographically valid, thereby allowing them to impersonate a user from that Identity Provider, aka a key confusion issue.
