* Advisory ID: DRUPAL-SA-CONTRIB-2017-072 * Project: Clientside Validation [1] (third-party module) * Version: 7.x * Date: 2017-September-06 * Security risk: 16/25 ( Critical) AC:Basic/A:None/CI:Some/II:Some/E:Theoretical/TD:All [2] * Vulnerability: Arbitrary PHP code execution

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

The Clientside Validation module enables you to have clientside (Javascript) validation on your forms.

The module does not sufficiently validate parameters of a POST request made when validating a CAPTCHA.

For the 1.x version of this module, this vulnerability is mitigated by the fact that the CAPTCHA module must be enabled and the 'validate captcha' option of the Clientside Validation module must be enabled (this option is enabled by default).

For the 2.x version of this module, this vulnerability is mitigated by the fact that the CAPTCHA module must be enabled and the Clientside Validation captcha submodule must be enabled.

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

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

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

* Clientside Validation 7.x-1.x versions prior to 7.x-1.44. * Clientside Validation 7.x-2.x versions prior to 7.x-2.0-beta1.

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

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

* If you use the 1.x version of Clientside Validation module for Drupal 7.x, upgrade to Clientside Validation 7.x-1.45 [5] * If you use the 2.x version of Clientside Validation module for Drupal 7.x, upgrade to Clientside Validation 7.x-2.0-beta2 [6]
