* Advisory ID: DRUPAL-SA-CONTRIB-2017-027 * Project: AES encryption [1] (third-party module) * Version: 7.x, 8.x * Date: 2017-March-01
-------- DESCRIPTION ---------------------------------------------------------
This module provides an API that allows other modules to encrypt and decrypt data using the AES encryption algorithm.
The module does not follow requirements for encrypting data safely. An attacker who gains access to data encrypted with this module could decrypt it more easily than should be possible. The maintainer has opted not to fix these weaknesses. See solution section for details on how to migrate to a supported and more secure AES encryption module.
-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------
* /A CVE identifier [2] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./
-------- VERSIONS AFFECTED ---------------------------------------------------
* All versions of the AES module
Drupal core is not affected. If you do not use the contributed AES encryption [3] module, there is nothing you need to do.
-------- SOLUTION ------------------------------------------------------------
If you're using the AES only because Drupal Remote Dashboard (DRD) [4] and Drupal Remote Dashboard Server (DRD Server) [5] depend on it, then update to the latest versions of DRD or DRD Server and disable the AES module -- those modules no longer depend on it.
In all other situations, you can replace the AES module with the Real AES [6] module:
* If you don't have a recent backup, make a backup of your site's database and codebase. Consider taking your site offline (e.g. using Drupal's maintenance mode) as some features may not work properly during this upgrade process. * *Do NOT follow the normal uninstall process for the AES module.* The uninstall process would delete your encryption key and make it impossible to recover your data! Instead, disable the module and delete the AES module directory *without uninstalling the module.* * Download and extract the latest release of Real AES [7] * Download and extract the latest release of Key [8] * Enable the Real AES, Key and AES compatibility modules * Use the Key [9] module to create a new 128-bit encryption key with the name "Real AES Key". * Clear all your Drupal caches. * Modules that depend on AES and store encrypted data will continue to function as normal. They should decrypt and re-encrypt any stored data. The Real AES module provides some functions from the AES module (like, aes_encrypt() and aes_decrypt()) which can decrypt using your old key, but will re-encrypt using the new key and more correct AES encryption.
