Drupal — система управления контентом с открытым исходным кодом. На Drupal работает более миллиона сайтов — от личных блогов до сайтов компаний, политических партий и государственных организаций.

Drupal 4.6.x before 4.6.7 and 4.7.0, when running on Apache with mod_mime, does not properly handle files with multiple extensions, which allows remote attackers to upload, modify, or execute arbitrary files in the files directory.

SQL injection vulnerability in Drupal 4.6.x before 4.6.7 and 4.7.0 allows remote attackers to execute arbitrary SQL commands via the (1) count and (2) from variables to (a) database.mysql.inc, (b) database.pgsql.inc, and (c) database.mysqli.inc.

Cross-site scripting (XSS) vulnerability in the project module (project.module) in Drupal 4.5 and 4.6 allows remote attackers to inject arbitrary web script or HTML via unknown attack vectors.

Session fixation vulnerability in Drupal 4.5.x before 4.5.8 and 4.6.x before 4.5.8 allows remote attackers to gain privileges by tricking a user to click on a URL that fixes the session identifier.

Cross-site scripting (XSS) vulnerability in Drupal 4.5.x before 4.5.8 and 4.6.x before 4.5.8 allows remote attackers to inject arbitrary web script or HTML via unknown attack vectors.

CRLF injection vulnerability in Drupal 4.5.x before 4.5.8 and 4.6.x before 4.5.8 allows remote attackers to inject headers of outgoing e-mail messages and use Drupal as a spam proxy.

Drupal 4.5.x before 4.5.8 and 4.6.x before 4.5.8, when menu.module is used to create a menu item, does not implement access control for the page that is referenced, which might allow remote attackers to access administrator pages.

** DISPUTED ** Drupal allows remote attackers to conduct cross-site scripting (XSS) attacks via an IMG tag with an unusual encoded Javascript function name, as demonstrated using variations of the alert() function. NOTE: a followup by the vendor suggests that the issue does not exist in 4.5.6 or 4.6.4 when "Filtered HTML" is enabled, and since "Full HTML" would not filter HTML by design, perhaps this should not be included in CVE.

Drupal 4.5.0 through 4.5.5 and 4.6.0 through 4.6.3, when running on PHP5, does not correctly enforce user privileges, which allows remote attackers to bypass the "access user profiles" permission.

Interpretation conflict in file.inc in Drupal 4.5.0 through 4.5.5 and 4.6.0 through 4.6.3 allows remote authenticated users to inject arbitrary web script or HTML via HTML in a file with a GIF or JPEG file extension, which causes the HTML to be executed by a victim who views the file in Internet Explorer as a result of CVE-2005-3312. NOTE: it could be argued that this vulnerability is due to a design flaw in Internet Explorer and the proper fix should be in that browser; if so, then this should not be treated as a vulnerability in Drupal.
