DESCRIPTION:
r0t has reported some vulnerabilities in Fineshop, which can be
exploited by malicious people to conduct cross-site scripting attacks
and SQL injection attacks.

1) Input passed to the "id_produc", "promocja", and "wysw" parameters
in index.php is not properly sanitised before being returned to the
user. This can be exploited to execute arbitrary HTML and script code
in a user's browser session in context of an affected site.

2) Input passed to the "id_produc", "id_kat", and "produkt"
parameters in index.php is not properly sanitised before being used
in a SQL query. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.

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