Etano 1.x <= Multiple Cross Site Scripting Vulnerabilities

1. OVERVIEW
Etano 1.x versions are vulnerable to Cross Site Scripting.

2. BACKGROUND
The community builder script we provide - Etano - was built entirely
based on requests from customers of our previous dating package
(Dating Site Builder). Almost every feature ever requested was built
into Etano to help you build a better site for your community members.
You can use Etano to start up a dating site, a social networking site,
a classifieds site or any other type of site involving groups of
people, companies, products.

3. VULNERABILITY DESCRIPTION
Multiple parameters were not properly sanitized upon submission to
join.php, search.php, photo_search.php and photo_view.php , which
allows attacker to conduct Cross Site Scripting attack. This may allow
an attacker to create a specially crafted URL that would execute
arbitrary script code in a victim's browser.
