Unrestricted file upload vulnerability in the BlogAPI module in Drupal 5.x before 5.10 and 6.x before 6.4 allows remote authenticated users to execute arbitrary code by uploading a file with an executable extension, which is not validated.

Update to 6.4, security fixes: SA-2008-047 (http://drupal.org/node/295053) - multiple XSS issues (CVE-2008-3740, CVE-2008-3741) - unrestricted upload vulnerability (CVE-2008-3742) - multiple CSRF issues (CVE-2008-3743, CVE-2008-3744) - upload module privilege escalation (CVE-2008-3745) Remember to log in to your site as the admin user before upgrading this package. After upgrading the package, browse to http://host/drupal/update.php to run the upgrade script.

The Drupal Project reports :

A bug in the output filter employed by Drupal makes it possible for malicious users to insert script code into pages (cross site scripting or XSS). A bug in the private filesystem trusts the MIME type sent by the browser, enabling malicious users with the ability to upload files to execute cross site scripting attacks.

The BlogAPI module does not validate the extension of uploaded files, enabling users with the 'administer content with blog api' permission to upload harmful files. This bug affects both Drupal 5.x and 6.x.

Drupal forms contain a token to protect against cross site request forgeries (CSRF). The token may not be validated properly for cached forms and forms containing AHAH elements. This bug affects Drupal 6.x.

User access rules can be added or deleted upon accessing a properly formatted URL, making such modifications vulnerable to cross site request forgeries (CSRF). This may lead to unintended addition or deletion of an access rule when a sufficiently privileged user visits a page or site created by a malicious person. This bug affects both Drupal 5.x and 6.x.

The Upload module in Drupal 6 contains privilege escalation vulnerabilities for users with the 'upload files' permission. This can lead to users being able to edit nodes which they are normally not allowed to, delete any file to which the webserver has sufficient rights, and download attachments of nodes to which they have no access. Harmful files may also be uploaded via cross site request forgeries (CSRF). These bugs affect Drupal 6.x.
