* Advisory ID: DRUPAL-SA-CONTRIB-2012-139 * Project: PDFThumb [1] (third-party module) * Version: 7.x * Date: 2012-September-12 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: OS Injection
-------- DESCRIPTION ---------------------------------------------------------
PDFThumb module creates thumbnail images of PDF files. The module doesn't sufficiently escape user-entered values when executing commands on the server allowing an attacker to execute whatever commands are available to the web server user (e.g. www-data). This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Administer PDFThumb".
