DISPUTED Cross-site request forgery (CSRF) vulnerability in Drupal 7.12 and earlier allows remote attackers to hijack the authentication of arbitrary users for requests that end a session via the user/logout URI. NOTE: the vendor disputes the significance of this issue, by considering the "security benefit against platform complexity and performance impact" and concluding that a change to the logout behavior is not planned because "for most sites it is not worth the trade-off."
The hookcomments 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5.3 does not pass publication status, which might allow attackers to bypass access restrictions and trigger e-mail with unpublished comments from some modules, as demonstrated by (1) Organic groups and (2) Subscriptions.
CRLF injection vulnerability in the drupalgoto 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.
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 PHPSELF; and (2) allow remote authenticated administrators to inject arbitrary web script or HTML via custom content type names.
Multiple cross-site scripting (XSS) vulnerabilities in Drupal before 4.6.11, and 4.7 before 4.7.5, allow remote attackers to inject arbitrary web script or HTML via unspecified parameters in the (1) filter and (2) system modules. NOTE: some of these details are obtained from third party information.
Multiple cross-site scripting (XSS) vulnerabilities in the XML parser in Drupal 4.6.x before 4.6.10 and 4.7.x before 4.7.4 allow remote attackers to inject arbitrary web script or HTML via a crafted RSS feed.
Cross-site scripting (XSS) vulnerability in user.module in Drupal 4.6 before 4.6.9, and 4.7 before 4.7.3, allows remote attackers to inject arbitrary web script or HTML via the msg parameter. NOTE: portions of these details are obtained from third party information.
Drupal 4.6.x before 4.6.7 and 4.7.0, when running on Apache with modmime, does not properly handle files with multiple extensions, which allows remote attackers to upload, modify, or execute arbitrary files in the files directory.
