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.

Drupal 6.x before 6.13 does not prevent users from modifying user signatures after the associated comment format has been changed to an administrator-controlled input format, which allows remote authenticated users to inject arbitrary web script, HTML, and possibly PHP code via a crafted user signature.

Drupal 5.x before 5.19 and 6.x before 6.13 does not properly sanitize failed login attempts for pages that contain a sortable table, which includes the username and password in links that can be read from (1) the HTTP referer header of external web sites that are visited from those links or (2) when page caching is enabled, the Drupal page cache.

Advanced Forum 6.x before 6.x-1.1, a module for Drupal, does not prevent users from modifying user signatures after the associated comment format has been changed to an administrator-controlled input format, which allows remote authenticated users to inject arbitrary web script, HTML, and possibly PHP code via a crafted user signature.

Cross-site scripting (XSS) vulnerability in Advanced Forum 5.x before 5.x-1.1 and 6.x before 6.x-1.1, a module for Drupal, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Unspecified vulnerability in LoginToboggan 6.x-1.x before 6.x-1.5, a module for Drupal, when "Allow users to login using their e-mail address" is enabled, allows remote blocked users to bypass intended access restrictions via unspecified vectors.

Unspecified vulnerability in Views Bulk Operations 5.x-1.x before 5.x-1.4 and 6.x-1.x before 6.x-1.7, a module for Drupal, allows remote attackers to bypass intended access restrictions and modify "nodes or classes of nodes" via unknown vectors, probably related to registered procedures (aka actions).

Cross-site scripting (XSS) vulnerability in the term data detail page in Taxonomy manager 5.x before 5.x-1.2, a module for Drupal, allows remote authenticated users, with administer taxonomy privileges or the ability to use free tagging to add taxonomy terms, to inject arbitrary web script or HTML via "Parent and related terms."

Multiple cross-site scripting (XSS) vulnerabilities in Booktree 5.x before 5.x-7.3 and 6.x before 6.x-1.1, a module for Drupal, allow remote attackers to inject arbitrary web script or HTML via the (1) node title and (2) node body in a tree root page.

Cross-site scripting (XSS) vulnerability in the administrative page interface in Taxonomy manager 5.x before 5.x-1.2 and 6.x before 6.x-1.1, a module for Drupal, allows remote authenticated users, with administer taxonomy privileges or the ability to use free tagging to add taxonomy terms, to inject arbitrary web script or HTML via (1) vocabulary names, (2) synonyms, and (3) term names.
