Language:

Synopsis

The remote host has a single-sign-on service provider installed which is vulnerable to a user attribute forgery issue.

Description

The version of Shibboleth Service Provider installed on the remote host is version 2.0 prior to 2.6. As a result it is affected by a user attribute forgery issue which could allow an attacker to impersonate a valid user and gain access to sensitive information.
