ruby-saml: The Ruby SAML library is for implementing the client side of a SAMLauthorization
CVE-2024-45409 is fixed in ruby-saml on 1 platform, first by ruby-saml 1.7.2-1ubuntu0.1~esm1, released September 10, 2024. It is not reported as exploited. Patch Radar priority: Routine.
The Ruby SAML library is for implementing the client side of a SAMLauthorization. Ruby-SAML in <= 12.2 and 1.13.0 <= 1.16.0 does not properlyverify the signature of the SAML Response. An unauthenticated attacker withaccess to any signed saml document (by the IdP) can thus forge a SAMLResponse/Assertion with arbitrary contents. This would allow the attackerto log in as arbitrary user within the vulnerable system. Thisvulnerability is fixed in 1.17.0 and 1.12.3.
