  • Project: Drupal core
  • Version: 6.x, 7.x
  • Date: 2014-November-19

Description

Session hijacking (Drupal 6 and 7)

A specially crafted request can give a user access to another user’s session, allowing an attacker to hijack a random session.

This attack is known to be possible on certain Drupal 7 sites which serve both HTTP and HTTPS content (“mixed-mode”), but it is possible there are other attack vectors for both Drupal 6 and Drupal 7.

Denial of service (Drupal 7 only)

Drupal 7 includes a password hashing API to ensure that user supplied passwords are not stored in plain text.

A vulnerability in this API allows an attacker to send specially crafted requests resulting in CPU and memory exhaustion. This may lead to the site becoming unavailable or unresponsive (denial of service).

This vulnerability can be exploited by anonymous users.

 

CVE identifier(s) issued

  • A CVE identifier will be requested, and added upon issuance, in accordance
    with Drupal Security Team processes.
