Discussion

WordPress 'wp-admin/includes/file.php' Arbitrary File Upload Vulnerability

WordPress is prone to a vulnerability that lets attackers upload arbitrary files. The issue occurs because the application fails to adequately sanitize user-supplied input.

An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible.

Note that this issue arises only in certain Apache configurations that use the Add* directives and PHP to facilitate handling of files with multiple extensions.

WordPress 2.8.5 and prior versions are vulnerable.
