Detailsinfo

A vulnerability was found in Drupal 7.33 (Content Management System). It has been classified as problematic. This affects an unknown part of the component Password Hashing API. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

The password hashing API in Drupal 7.x before 7.34 and the Secure Password Hashes (aka phpass) module 6.x-2.x before 6.x-2.1 for Drupal allows remote attackers to cause a denial of service (CPU and memory consumption) via a crafted request.

The weakness was presented 11/19/2014 by Michael Cullum, Javier Nieto and Andrés Rojas Guerrero as DRUPAL-SA-CORE-2014-006 as confirmed security advisory (Website). The advisory is shared at drupal.org. This vulnerability is uniquely identified as CVE-2014-9016 since 11/20/2014. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available. The advisory points out:

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).

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 79679 (Fedora 20 : drupal7-7.34-1.fc20 (2014-15528)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 13074 (Drupal Core Password Hashing API Denial of Service Vulnerability (SA-CORE-2014-006)). The advisory illustrates:

If you have configured a custom session.inc file for your Drupal 6 or Drupal 7 site you also need to make sure that it is not prone to the same session hijacking vulnerability disclosed in this security advisory. If you have configured a custom password.inc file for your Drupal 7 site you also need to make sure that it is not prone to the same denial of service vulnerability disclosed in this security advisory.

Upgrading to version 6.x or 7.34 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (98861), Exploit-DB (35415), Tenable (79679), SecurityFocus (BID 71195†) and Secunia (SA59164†).
