Descriptions

Spring Security versions 5.2.x prior to 5.2.4 and 5.3.x prior to 5.3.2 contain a signature wrapping vulnerability during SAML response validation. When using the spring-security-saml2-service-provider component, a malicious user can carefully modify an otherwise valid SAML response and append an arbitrary assertion that Spring Security will accept as valid.

Spring Security versiones 5.2.x anteriores a 5.2.4 y versiones 5.3.x anteriores a 5.3.2, contienen una vulnerabilidad de empaquetado de firma durante la comprobación de respuesta SAML. Cuando se usa el componente spring-security-saml2-service-provider, un usuario malicioso puede modificar cuidadosamente una respuesta SAML válida y agregar una afirmación arbitraria que Spring Security aceptará como válida.
