Cross-site scripting (XSS) vulnerability in Drupal 5.x before 5.17 and 6.x before 6.11, as used in vbDrupal before 5.17.0, allows remote attackers to inject arbitrary web script or HTML via crafted UTF-8 byte sequences before the Content-Type meta tag, which are treated as UTF-7 by Internet Explorer 6 and 7.
