Advanced Poll does not adequately authenticate users

Overview

Advanced Poll is a polling system written in PHP for use on web sites. When a flat file database is used, Advanced Poll does not adequately authenticate users, thereby allowing any user to gain Advanced Poll administrative privileges.

II. Impact

Attackers may login as the administrative user without authentication and gain adminstrator privileges for Advanced Poll.

III. Solution
