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 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.
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5.3 does not pass publication status, which might allow attackers to bypass access restrictions and trigger e-mail with unpublished comments from some modules, as demonstrated by (1) Organic groups and (2) Subscriptions.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 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.
