"The version of Shibboleth Service Provider installed on the remote is prior to 3.5.0.1. It is, therefore, affected by
a vulnerability. The OpenSAML C++ library before 3.3.1 allows forging of signed SAML messages via parameter manipulation
(when using SAML bindings that rely on non-XML signatures).

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
