CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Y&K Iletism Formu
http://secunia.com/product/15899/

DESCRIPTION:
GeFORC3 (G3) has discovered some vulnerabilities in Y&K Iletisim
Formu, which can be exploited by malicious people to conduct script
insertion attacks.

Input passed to the "ad", "sehir", "yas", "cins", "tel", "mail", and
"mesaj" parameters in iletisim.asp is not properly sanitised before
being used. This can be exploited to insert arbitrary HTML and script
code, which will be executed in an administrator's browser session in
context of an affected site when the malicious data is viewed.

The vulnerabilities are confirmed in a version downloaded 2007-10-01.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
