CVE-2010-2234: Apache CouchDB Cross Site Request Forgery Attack
===============================================================

:Date: 21.02.2010

:Affected: Apache CouchDB 0.8.0 to 0.11.1

:Severity: Important

:Vendor: The Apache Software Foundation

Description
===========

Apache CouchDB versions prior to version :ref:`0.11.1 <release/0.11.1>` are
vulnerable to `Cross Site Request Forgery`_ (CSRF) attacks.

.. _Cross Site Request Forgery: http://en.wikipedia.org/wiki/Cross-site_request_forgery

Mitigation
==========

All users should upgrade to CouchDB :ref:`0.11.2 <release/0.11.2>`
or :ref:`1.0.1 <release/1.0.1>`.

Upgrades from the :ref:`0.11.x <release/0.11.x>` and
:ref:`0.10.x <release/0.10.x>` series should be seamless.

Users on earlier versions should consult with upgrade notes.

Example
=======

A malicious website can `POST` arbitrary JavaScript code to well
known CouchDB installation URLs (like http://localhost:5984/)
and make the browser execute the injected JavaScript in the
security context of CouchDB's admin interface Futon.

Unrelated, but in addition the JSONP API has been turned off
by default to avoid potential information leakage.
