VERIFY ADVISORY:
http://secunia.com/advisories/33211/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, Exposure of system
information, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
Phpclanwebsite 1.x
http://secunia.com/advisories/product/6884/

DESCRIPTION:
s4avrd0w has discovered some vulnerabilities in Phpclanwebsite, which
can be exploited by malicious people to disclose sensitive information
or conduct SQL injection and cross-site scripting attacks.

1) Input passed to the "boxname" parameter in
theme/superchrome/box.php and to the "theme" parameter in
phpclanwebsite/footer.php is not properly verified before being used
to include files. This can be exploited to include arbitrary files
from local resources via directory traversal attacks.

Successful exploitation requires that "magic_quotes_gpc" is disabled
and "register_globals" is enabled.

2) Input passed to the "page" parameter in index.php, to the
"form_id" parameter in pcw/processforms.php, to the "pcwlogin"
parameter in pcw/setlogin.php, and to the "searchvalue" parameter in
pcw/downloads.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 of this vulnerability requires that
"magic_quotes_gpc" is disabled.

3) Input passed to the "whichfield" parameter in pcw/downloads.php is
not properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

4) Input passed to the "page" parameter 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.

NOTE: Other issues similar to this vulnerability may also be
present.

The vulnerabilities are confirmed in version 1.23.3 Fix Pack #5.
Other versions may also be affected.

SOLUTION:
