{"id":"DEBIAN-CVE-2024-45409","details":"The Ruby SAML library is for implementing the client side of a SAML authorization. Ruby-SAML in \u003c= 12.2 and 1.13.0 \u003c= 1.16.0 does not properly verify the signature of the SAML Response. An unauthenticated attacker with access to any signed saml document (by the IdP) can thus forge a SAML Response/Assertion with arbitrary contents. This would allow the attacker to log in as arbitrary user within the vulnerable system. This vulnerability is fixed in 1.17.0 and 1.12.3.","modified":"2026-09-15T09:03:11.100675993Z","published":"2024-09-10T19:15:22.030Z","upstream":["CVE-2024-45409"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-45409"}],"affected":[{"package":{"name":"ruby-saml","ecosystem":"Debian:12","purl":"pkg:deb/debian/ruby-saml?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.13.0-1+deb12u1"}]}],"versions":["1.13.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-45409.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
