Cross-site scripting (XSS) vulnerability in the upload module (upload.module) in Drupal 4.6.x before 4.6.8 and 4.7.x before 4.7.2 allows remote attackers to inject arbitrary web script or HTML via the uploaded filename.

SQL injection vulnerability in Drupal 4.6.x before 4.6.7 and 4.7.0 allows remote attackers to execute arbitrary SQL commands via the (1) count and (2) from variables to (a) database.mysql.inc, (b) database.pgsql.inc, and (c) database.mysqli.inc.

Drupal 4.6.x before 4.6.7 and 4.7.0, when running on Apache with mod_mime, does not properly handle files with multiple extensions, which allows remote attackers to upload, modify, or execute arbitrary files in the files directory.
