View online: https://www.drupal.org/node/2822366 * Advisory ID: DRUPAL-SA-CONTRIB-2016-054 * Project: Tripal BLAST UI [1] (third-party module) * Version: 7.x * Date: 2016-October-26 * Security risk: 20/25 ( Highly Critical) AC:Basic/A:None/CI:All/II:All/E:Theoretical/TD:All [2] * Vulnerability: Remote code execution -------- DESCRIPTION --------------------------------------------------------- This module enables you to run NCBI BLAST jobs on the host system. The module doesn't sufficiently validate advanced options available to users submitting BLAST jobs, thereby exposing the ability to enter a short snippet of shell code that will be executed when the BLAST job is run. This vulnerability only requires the attacker to have minimal permissions on the site (for example, "View published content") and therefore can be exploited by untrusted or unauthenticated users in most cases. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Tripal BLAST UI 7.x-1.x versions prior to 7.x-1.2 Drupal core is not affected. If you do not use the contributed Tripal BLAST UI [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Tripal BLAST UI module for Drupal 7.x, upgrade to Tripal BLAST UI 7.x-1.2 [5] Also see the Tripal BLAST UI [6] project page. -------- REPORTED BY --------------------------------------------------------- * Nick Booher [7] * David Rothstein [8] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ * Lacey-Anne Sanderson [9] the module maintainer * Nick Booher [10] * David Rothstein [11] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at https://www.drupal.org/contact [12].
