   * Advisory ID: DRUPAL-SA-CONTRIB-2015-096
   * Project: Services [1]     (third-party module)
   * Version: 7.x
   * Date: 2015-April-15
   * Security risk: 16/25 ( Critical)
     AC:None/A:None/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
   * Vulnerability: Access bypass, Arbitrary PHP code execution

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

Services module enables you to expose an API to third party systems.

.... Access bypass (file upload and execution)

The resource/endpoint for uploading files does not properly sanitize the
filename of uploaded files. This vulnerability is mitigated by the fact that
the "File > Create" resource must be enabled and an attacker must have a role
with the Services "Save file information" permission.

.... Private fields information displayed

Services does not check field_access when displaying entities so some private
field information may be displayed. This vulnerability is only affecting
sites using the field_permissions module configured to hide fields from
anonymous users.


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

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

-------- VERSIONS AFFECTED

Drupal core is not affected. If you do not use the contributed Services [4]
module,
