Zeroboard Arbitrary File Upload Vulnerability

Zeroboard is prone to an arbitrary file-upload vulnerability.

An attacker can exploit this vulnerability to upload a malicious '.htaccess' file that will remove restrictions on further file-uploads and executions.

Note that to exploit this vulnerability, the Apache 'mod_mime' module must be installed and the web directory must be configured with the Apache 'AllowOverride All' or 'AllowOverride FileInfo' webserver directives.

This issue affects versions 4.1pl8 and prior.
