# Description:
# Attacker can combine "CSRF vulnerability in Trean Bookmarks (defaultly
installed on Horde Groupware)" and
# "Stored XSS vulnerability in Horde TagCloud (defaultly installed)"
vulnerabilities to steal victim's emails.

# Also:
# Attacker can use 3 different reflected XSS vulnerability to exploit
Remote Command Execution, SQL Injection and Code Execution.
# To steal e-mails, attacker will send an e-mail to victim and victim
will click the attacker's website.
# So, victim's inbox will be dumped in attacker's FTP.
# All of them vulnerabillities are valid for all Horde Webmail versions.

# Attacker will exploit the CSRF and XSS with: index.html
# Attacker will steal and post the emails with: stealer.js
# Attacker will save the emails with: stealer.php

# index.html Codes:
<script>
