Details:

Cross-Site Scripting (WASC-08):

Example of XSS for IE:

http://site/index_admin_login.php?return_path=%27%22%20style=xss:expression(alert(document.cookie))%201

Cross-Site Request Forgery (WASC-09):

http://site/index_admin_login.php

Lack of protection in login form, such as captcha, leads to possibility of conducting CSRF attacks, which I wrote about in the article Attacks on unprotected login forms (http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2011-April/007773.html). It allows to conduct remote login. But the from isn't vulnerable to Brute Force, since captcha appears after the first attempt.

Also it can be used for redirection. For these attacks it's needed to have working login and password:
