* Advisory ID: DRUPAL-SA-CONTRIB-2014-120
* Project: Piwik Web Analytics [1] (third-party module)
* Version: 7.x
* Date: 2014-December-10
* Security risk: 11/25 ( Moderately Critical)
AC:None/A:User/CI:Some/II:None/E:Theoretical/TD:Uncommon [2]
* Vulnerability: Information Disclosure
-------- DESCRIPTION
---------------------------------------------------------
This module enables you to integrate Drupal with Piwik Web Analytics.
The module leaks the site specific hash salt to authenticated users when
user-id tracking is turned on.
This vulnerability is mitigated by the fact that user-id tracking must be
turned on and the attacker needs to have an account on the site.
-------- CVE IDENTIFIER(S) ISSUED
--------------------------------------------
* /A CVE identifier [3] will be requested, and added upon issuance, in
accordance
with Drupal Security Team processes./
-------- VERSIONS AFFECTED
---------------------------------------------------
* Piwik Web Analytics 7.x-2.6. Neither earlier nor later versions are
affected.
Drupal core is not affected. If you do not use the contributed Piwik Web
Analytics [4] module,
there is nothing you need to do.
-------- SOLUTION
------------------------------------------------------------
Install the latest version:
* If you use the Piwik Web Analytics module for Drupal 7.x, upgrade to
Piwik
Web Analytics 7.x-2.7 [5]
Affected sites are urged to generate a new hash salt and store it in
settings.php.
.... Methods to generate a new hash salt
* With drush:
drush php-eval 'echo(drupal_random_key()) . "\n";'
* With openssl:
openssl rand -base64 32
.... How to replace the hash salt
1) Open your settings.php file (e.g., sites/default/settings.php
2) Locate the variable $drupal_hash_salt:
<?php
/**
* Salt for one-time login links and cancel links, form tokens, etc.
* [...]
*/
$drupal_hash_salt = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
?>
3) Replace the value and safe the file
4) Flush all caches either from within the administrative UI
(/Administration » Configuration » Development » Performance/) or by
issuing drush cache-clear all
.... Effects caused by replacing the hash salt
* Passwort reset links generated before the new hash salt will not work
anymore. Affected users need to request a new password reset link.
* Existing image style urls will stop working. A cache flush is necessary
such that all tags are updated.
If immediate installation / regeneration of the hash salt is not possible,
then disable user-id tracking at once.
