ruby-saml

SEVERITY

CVSS v3.x: 10.0 (Critical)

PATCHED VERSIONS

• ~> 1.12.3
• >= 1.17.0

DESCRIPTION

Ruby-SAML in <= 12.2 and 1.13.0 <= 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.
