CVE-2025-25292

ruby-saml provides security assertion markup language (SAML) single sign-on (SSO) for Ruby. An authentication bypass vulnerability was found in ruby-saml prior to versions 1.12.4 and 1.18.0 due to a parser differential. ReXML and Nokogiri parse XML differently, the parsers can generate entirely different document structures from the same XML input. That allows an attacker to be able to execute a Signature Wrapping attack. This issue may lead to authentication bypass. Versions 1.12.4 and 1.18.0 contain a patch for the issue.

Summary
  • (es) ruby-saml proporciona inicio de sesión único (SSO) con lenguaje de marcado para aserciones de seguridad (SAML) para Ruby. Se detectó una vulnerabilidad de omisión de autenticación en ruby-saml anterior a las versiones 1.12.4 y 1.18.0 debido a una diferencia en el analizador. ReXML y Nokogiri analizan XML de forma diferente; los analizadores pueden generar estructuras de documento completamente distintas a partir de la misma entrada XML. Esto permite a un atacante ejecutar un ataque de encapsulado de firmas. Este problema puede provocar la omisión de autenticación. Las versiones 1.12.4 y 1.18.0 incluyen un parche para este problema.
