Описание

Множественные уязвимости обнаружены в Друпал.

CROSS SITE SCRIPTING

A bug in the output filter employed by Drupal makes it possible for malicious
users to insert script code into pages (cross site scripting [
http://en.wikipedia.org/wiki/Cross-site_scripting ] or XSS).

A bug in the private filesystem trusts the MIME type sent by the browser,
enabling malicious users with the ability to upload files to execute cross site
scripting attacks.

These bugs affects both Drupal 5.x and 6.x.

ARBITRARY FILE UPLOADS VIA BLOGAPI

The BlogAPI module does not validate the extension of uploaded files, enabling
users with the "administer content with blog api" permission to upload harmful
files.

This bug affects both Drupal 5.x and 6.x.

CROSS SITE REQUEST FORGERIES

Drupal forms contain a token to protect against cross site request forgeries [
http://en.wikipedia.org/wiki/Cross-site_request_forgery ] (CSRF). The token may
not be validated properly for cached forms and forms containing AHAH elements.

This bug affects Drupal 6.x.

User access rules can be added or deleted upon accessing a properly formatted
URL, making such modifications vulnerable to cross site request forgeries
(CSRF). This may lead to unintended addition or deletion of an access rule when
a sufficiently privileged user visits a page or site created by a malicious
person.

This bug affects both Drupal 5.x and 6.x.

VARIOUS UPLOAD MODULE VULNERABILITIES

The Upload module in Drupal 6 contains privilege escalation vulnerabilities for
users with the "upload files" permission. This can lead to users being able to
edit nodes which they are normally not allowed to, delete any file to which the
webserver has sufficient rights, and download attachments of nodes to which they
have no access. Harmful files may also be uploaded via cross site request
forgeries (CSRF).

These bugs affect Drupal 6.x.

Если вы не можете обновиться немедленно, вы можете применить патч, чтобы защитить вашу установку Друпал, пока вы не сделаете полноценное обновление. Патчи исправляют уязвимости безопасности, но не содержат некоторые исправления, которые есть в новых версиях.

• Для Drupal 5.9 нужно применить патч SA-2008-047-5.9.patch (http://drupal.org/files/sa-2008-047/SA-2008-047-5.9.patch)
• Для Drupal 6.3 нужно применить патч SA-2008-047-6.3.patch (http://drupal.org/files/sa-2008-047/SA-2008-047-6.3.patch)
