  * Advisory ID: DRUPAL-SA-CONTRIB-2016-062
  * Project: Elysia Cron [1]     (third-party module)
  * Version: 7.x
  * Date: 2016-November-30
  * Security risk: 11/25 ( Moderately Critical)
    AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
  * Vulnerability: Arbitrary PHP code execution

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

This module enables you to manage cron jobs.

The module allows users with the permission "Administer elysia cron" to
execute arbitrary PHP code via cron.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "Administer elysia cron". This permission is not marked
as "restricted".


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

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

-------- VERSIONS AFFECTED
---------------------------------------------------

  * Elysia cron 7.x-2.x versions prior to 7.x-2.4.

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

-------- SOLUTION
------------------------------------------------------------

Revoke the permission "Administer elysia cron" for untrusted users.

Elysia cron 7.x-2.4 [5] and up will indicate that the permission is
restricted.

Also see the Elysia Cron [6] project page.
