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.

The Upload module in Drupal 6.x before 6.4 allows remote authenticated users to edit nodes, delete files, and download unauthorized attachments via unspecified vectors.

Multiple cross-site request forgery (CSRF) vulnerabilities in forms in Drupal 6.x before 6.4 allow remote attackers to perform unspecified actions via unknown vectors, related to improper token validation for (1) cached forms and (2) forms with AHAH elements.

Multiple cross-site request forgery (CSRF) vulnerabilities in Drupal 5.x before 5.10 and 6.x before 6.4 allow remote attackers to hijack the authentication of administrators for requests that (1) add or (2) delete user access rules.

Drupal, probably 5.10 and 6.4, does not set the secure flag for the session cookie in an https session, which can cause the cookie to be sent in http requests and make it easier for remote attackers to capture this cookie.

Cross-site request forgery (CSRF) vulnerability in Drupal 6.x before 6.3 allows remote attackers to perform administrative actions via vectors involving deletion of OpenID identities.

The Drupal filter_xss_admin function in 5.x before 5.8 and 6.x before 6.3 does not "prevent use of the object HTML tag in administrator input," which has unknown impact and attack vectors, probably related to an insufficient cross-site scripting (XSS) protection mechanism.

Multiple cross-site scripting (XSS) vulnerabilities in Drupal 6.x before 6.3 allow remote attackers to inject arbitrary web script or HTML via vectors related to (1) free tagging taxonomy terms, which are not properly handled on node preview pages, and (2) unspecified OpenID values.

SQL injection vulnerability in the Schema API in Drupal 6.x before 6.3 allows remote attackers to execute arbitrary SQL commands via vectors related to "an inappropriate placeholder for 'numeric' fields."

Cross-site request forgery (CSRF) vulnerability in Drupal 5.x before 5.8 and 6.x before 6.3 allows remote attackers to perform administrative actions via vectors involving deletion of "translated strings."

Session fixation vulnerability in Drupal 5.x before 5.9 and 6.x before 6.3, when contributed modules "terminate the current request during a login event," allows remote attackers to hijack web sessions via unknown vectors.
