   * Advisory ID: DRUPAL-SA-CONTRIB-2015-030
   * Project: Amazon AWS [1]     (third-party module)
   * Version: 7.x
   * Date: 2015-January-28
   * Security risk: 14/25 ( Moderately Critical)
     AC:None/A:None/CI:None/II:Some/E:Theoretical/TD:Default [2]
   * Vulnerability: Access bypass

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

Amazon AWS module provides integration with Amazon Web Services (AWS).

A malicious user could potentially guess an access token and trigger the
creation of new backups by making a request to a specially-crafted URL. If
the number of stored backups was limited, an attacker could exceed the limit
by calling the URL multiple times, thereby resulting in the loss of older
backup states that would get replaced with the newly generated ones.

This vulnerability is mitigated by the fact that an attacker must know the
AWS Access Key Id (these are not secret).


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

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