Multiple cross-site scripting (XSS) vulnerabilities in the Token module before 4.7.x-1.5, and 5.x before 5.x-1.9, for Drupal; as used by the ASIN Field, e-Commerce, Fullname field for CCK, Invite, Node Relativity, Pathauto, PayPal Node, and Ubercart modules; allow remote authenticated users with a post comments privilege to inject arbitrary web script or HTML via unspecified vectors related to (1) comments, (2) vocabulary names, (3) term names, and (4) usernames.

CRLF injection vulnerability in the drupal_goto function in includes/common.inc Drupal 4.7.x before 4.7.8 and 5.x before 5.3 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.

Drupal 5.x before 5.3 does not apply its Drupal Forms API protection against the user deletion form, which allows remote attackers to delete users via a cross-site request forgery (CSRF) attack.

The hook_comments API in Drupal 4.7.x before 4.7.8 and 5.x before 5.3 does not pass publication status, which might allow attackers to bypass access restrictions and trigger e-mail with unpublished comments from some modules, as demonstrated by (1) Organic groups and (2) Subscriptions.

install.php in Drupal 5.x before 5.3, when the configured database server is not reachable, allows remote attackers to execute arbitrary code via vectors that cause settings.php to be modified.

The core Upload module in Drupal 4.7.x before 4.7.8 and 5.x before 5.3 places the .html extension on a whitelist, which allows remote attackers to conduct cross-site scripting (XSS) attacks by uploading .html files.

Drupal 5.2 and earlier does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary PHP code by invoking the drupal_eval function through a callback parameter to the default URI, as demonstrated by the _menu[callbacks][1][callback] parameter. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in Drupal.

Cross-site scripting (XSS) vulnerability in the subscription functionality in the Project issue tracking module before 4.7.x-1.5, 4.7.x-2.x before 4.7.x-2.5, and 5.x-1.x before 5.x-1.1 for Drupal allows remote authenticated users with project create or edit permissions to inject arbitrary web script or HTML via unspecified vectors involving a (1) individual or (2) overview form.

The Drupal Project module before 5.x-1.0, 4.7.x-2.3, and 4.7.x-1.3 and Project issue tracking module before 5.x-1.0, 4.7.x-2.4, and 4.7.x-1.4 do not properly enforce permissions, which allows remote attackers to (1) obtain sensitive via the Tracker Module and the Recent posts page; (2) obtain project names via unspecified vectors; (3) obtain sensitive information via the statistics pages; and (4) read CVS project activity.

Multiple cross-site scripting (XSS) vulnerabilities in the nodereference module in Drupal Content Construction Kit (CCK) before 4.7.x-1.6, and 5.x before 5.x-1.6 ,allow remote attackers to inject arbitrary web script or HTML via nodereference fields, when using (1) the plain formatter or (2) the autocomplete text field widget without Views.module.
