#
# HTML Form found in redirect page [high severity]
# Vulnerability description
# Manual confirmation is required for this alert.
# 
# An HTML form was found in the response body of this page.
# However, the current page redirects the visitor to another
# page by returning an HTTP status code of 301/302. Therefore,
# all browser users will not see the contents of this page
# and will not be able to interact with the HTML form. 
# 
# Sometimes programmers don't properly terminate
# the script after redirecting the user to another page. For example: 
# <?php
#     if (!isset($_SESSION["authenticated"])) {
#         header("Location: auth.php");
#     }
# ?>
# <title>Administration page</title>
# <form action="/admin/action" method="post">
#     <!-- ...  form inputs ...  -->
# </form>
#   
# <!-- ...  the rest of the administration page ...  -->
# 
# This script is incorrect because the script is not terminated
# after the "header("Location: auth.php");" line. An attacker can access
# the content the administration page by using an HTTP client that
# doesn't follow redirection (like HTTP Editor). This creates an authentication
# bypass vulnerability. The correct code would be 
# 
# <?php
#    if (!isset($_SESSION[auth])) {
#         header("Location: auth.php");
#         exit();
#     }
# ?>
# <title>Administration page</title>
# <form action="/admin/action" method="post">
#     <!-- ...  form inputs ...  -->
# </form>
#     
# <!-- ...  the rest of the administration page ...  -->
# 
# This vulnerability affects /mohachat-0.1.1/mohachat. 
# Discovered by: Scripting (HTML_Form_In_Redirect_Page.script). 
# Attack details
# Form action=''
