HIGH7.5EPSS 0.17%SimpleSAMLphp Improper Verification of Cryptographic Signature
發布日:2022/5/13修改日:2026/4/28
描述
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.
