[Drupal] Fwd: [Security-news] SA-CONTRIB-2015-028 - Shibboleth Authentication - Cross Site Request Forgery (CSRF)

[Hicks, Edward S. (Stu)]

Their report needs more info.  If you can get the admin's browser to go to an arbitrary URL while he's logged in then there's a whole lot more that you can do to than just fiddle with the Shib auto-assignment list.

There's a drupal/shib module security bug (see below). It doesn't sound too bad if you're not auto assigning roles.

Best,
Jason

  * Advisory ID: DRUPAL-SA-CONTRIB-2015-028
  * Project: Shibboleth authentication [1]     (third-party module)
  * Version: 6.x, 7.x
  * Date: 2015-January-21
  * Security risk: 13/25 ( Moderately Critical)
    AC:Basic/A:None/CI:None/II:Some/E:Theoretical/TD:All [2]
  * Vulnerability: Cross Site Request Forgery

-------- DESCRIPTION
---------------------------------------------------------

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.

  * Shibboleth Authentication 6.x-4.x versions prior to 6.x-4.1.
