Cross-site scripting (XSS) vulnerability in the insertion filter in the Flickr Drupal module 5.x before 5.x-1.3 and 6.x before 6.x-1.0-alpha allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The Simple Access module for Drupal 5.x through 5.x-1.2-2 does not properly handle the privacy information for nodes, which might allow remote attackers to bypass intended access restrictions, and read or modify nodes, in opportunistic circumstances related to interaction between Simple Access and (1) Node clone or (2) Project issue tracking.

Cross-site scripting (XSS) vulnerability in the Archive 5.x before 5.x-1.8 module for Drupal allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Cross-site request forgery (CSRF) vulnerability in the aggregator module in Drupal 4.7.x before 4.7.11 and 5.x before 5.6 allows remote attackers to delete items from a feed as privileged users.

Interpretation conflict in Drupal 4.7.x before 4.7.11 and 5.x before 5.6, when Internet Explorer 6 is used, allows remote attackers to conduct cross-site scripting (XSS) attacks via invalid UTF-8 byte sequences, which are not processed as UTF-8 by Drupal's HTML filtering, but are processed as UTF-8 by Internet Explorer, effectively removing characters from the document and defeating the HTML protection mechanism.

Cross-site scripting (XSS) vulnerability in Drupal 4.7.x and 5.x, when certain .htaccess protections are disabled, allows remote attackers to inject arbitrary web script or HTML via crafted links involving theme .tpl.php files.

Cross-site scripting (XSS) vulnerability in the Devel module before 5.x-0.1 for Drupal allows remote attackers to inject arbitrary web script or HTML via a site variable, related to lack of escaping of the variable table.

Multiple SQL injection vulnerabilities in Drupal and vbDrupal 4.7.x before 4.7.9 and 5.x before 5.4 allow remote attackers to execute arbitrary SQL commands via modules that pass input to the taxonomy_select_nodes function, as demonstrated by the (1) taxonomy_menu, (2) ajaxLoader, and (3) ubrowser contributed modules.

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.

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.

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.

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.

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.

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.

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.

Multiple cross-site request forgery (CSRF) vulnerabilities in Drupal 5.x before 5.2 allow remote attackers to (1) delete comments, (2) delete content revisions, and (3) disable menu items as privileged users, related to improper use of HTTP GET and the Forms API.

Multiple cross-site scripting (XSS) vulnerabilities in Drupal 5.x before 5.2, and 4.7.x before 4.7.7, (1) allow remote attackers to inject arbitrary web script or HTML via "some server variables," including PHP_SELF; and (2) allow remote authenticated administrators to inject arbitrary web script or HTML via custom content type names.

The (1) Textimage 4.7.x before 4.7-1.2 and 5.x before 5.x-1.1 module for Drupal and the (2) Captcha 4.7.x before 4.7-1.2 and 5.x before 5.x-1.1 module for Drupal allow remote attackers to bypass the CAPTCHA test via an empty captcha element in $_SESSION.

The comment_form_add_preview function in comment.module in Drupal before 4.7.6, and 5.x before 5.1, and vbDrupal, allows remote attackers with "post comments" privileges and access to multiple input filters to execute arbitrary code by previewing comments, which are not processed by "normal form validation routines."
