Last modified
CVE-2018-7644 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.26% chance of exploitation in the next 30 days.
