Descripción

*** Pendiente de traducción *** Node-SAML is a SAML library not dependent on any frameworks that runs in Node. In versions 5.0.1 and below, Node-SAML loads the assertion from the (unsigned) original response document. This is different than the parts that are verified when checking signature. This allows an attacker to modify authentication details within a valid SAML assertion. For example, in one attack it is possible to remove any character from the SAML assertion username. This issue is fixed in version 5.1.0.
