IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Milkeyway Captive Portal 0.x
http://secunia.com/product/8751/

DESCRIPTION:
Francesco Ongaro has discovered multiple vulnerabilities in
Milkeyway, which can be exploited by malicious users to conduct SQL
injection attacks, and malicious people to conduct cross-site
scripting attacks and SQL injection attacks.

1) Input passed to the "username" parameter in auth.php and
logout.php, and to the "USERNAME" and "PASSWORD" cookie parameters in
chgpwd.php is not properly sanitised before being used in SQL queries.
This can be exploited to manipulate SQL queries by injecting arbitrary
SQL code.

Successful exploitation requires "magic_quotes_rpc" to be disabled.

2) Input passed to the "username", "password", and "filter"
parameters in admin/authuser.php and admin/userstatistics.php, to the
"teamname" parameter in admin/authgroup.php, and the "date" and "id"
parameters in admin/traffic.php is not properly sanitised before
being used in SQL queries. This can be exploited to manipulate SQL
queries by injecting arbitrary SQL code.

Successful exploitation requires access to the administration section
and "magic_quotes_rpc" to be disabled.

3) Input passed to the "username" parameter in
admin/userstatistics.php and the "ipAddress" parameter in
authuser.php is not properly sanitised before being returned to the
user. This can be exploited to execute arbitrary HTML and script code
in an administrative user's browser session in context of an affected
site.

The vulnerabilities have been confirmed in version 0.1.1. Other
versions may also be affected.

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