SA-CONTRIB-2015-028 - Shibboleth Authentication - Cross Site Request Forgery (CSRF)

Shibboleth Authentication module allows users to log in and get permissions based on federated (SAML2) authentication.

The roles that are assigned to users are based on a matching list. A malicious attacker can delete matching rules from the list by getting the administrator’s browser to make a request to a specially-crafted URL while the administrator is logged in.
