OSCommerce Session Fixation Vulnerability:SecurityFocus(情報元のブックマーク数)

OSCommerceにセッションフィクセーションの脆弱性が存在との事

When a client visits a OSCommerce web page, the server sends a cookie. That cookie will be the session cookie for every further requests. Thus, once logged in, the cookie will be used to authenticate the user.

When logging in (without cookies), the URL will look something like http://myserver/myapp/index.php?oscid=sometext

An attacker can send a link crafted like that http://myserver/myapp/index.php?oscid=arbitrarysession. If the admin/user follows the link and logs in, his cookie will still be arbitrarysession. Thus, the attacker can hijack the session because he set the cookie.
