* Advisory ID: DRUPAL-SA-CONTRIB-2013-080
* Project: Simplenews [1] (third-party module)
* Version: 6.x, 7.x
* Date: 2013-Month-DD
* Security risk: Moderately critical [2]
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting

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

This module enables you to publish and send newsletters to lists of
subscribers.
The module also includes an API that other modules can use to register
subscribers.
The module doesn't sufficiently sanitize e-mail addresses prior to
outputting. The provided forms (sign-up, mass import, ..) validate and only
allow valid e-mail addresses, but e-mail addresses could also be added
directly through the API, which does not validate.
This vulnerability is mitigated by the fact that the Simplnews module
performs input validation which prevents known attacks, so the injection
vector must be added another module (custom or contributed) without
validating the email address using the Simplenews API .


-------- CVE IDENTIFIER(S) ISSUED
--------------------------------------------

* /A CVE identifier [3] will be requested, and added upon issuance, in
accordance with Drupal Security Team processes./

---------------------------------------------------

* Simplenews 6.x-1.x versions prior to 6.x-1.5.
* Simplenews 7.x-1.x versions prior to 7.x-1.1.

Drupal core is not affected. If you do not use the contributed Simplenews [4]
module, there is nothing you need to do.
