TITLE:
PHPKIT Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA17479

VERIFY ADVISORY:
http://secunia.com/advisories/17479/

CRITICAL:
Highly critical

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

WHERE:
>From remote

SOFTWARE:
PHPKIT 1.x
http://secunia.com/product/2486/

DESCRIPTION:
Christopher Kunz has reported some vulnerabilities in PHPKIT, which
can be exploited by malicious people to conduct cross-site scripting
and script insertion attacks, disclose sensitive information, and
compromise a vulnerable system.

1) Some input isn't properly sanitised before being used. This can be
exploited to inject arbitrary HTML and script code, which will be
executed in a user's or administrator's browser session in context of
an affected site when the malicious user data is viewed.

2) Input passed to the "site_body" parameter in "admin/admin.php"
isn't properly sanitised before being returned to the user. This can
be exploited to execute arbitrary HTML and script code in an
administrator's browser session in context of an affected site.

Successful exploitation requires that "register_globals" is enabled.

3) Input passed to the referer HTTP header isn't properly sanitised
before being used. This can be exploited to inject arbitrary HTML and
script code, which will be executed in an administrator's browser
session in context of an affected site when the administrator views
referer statistics.

4) Input passed to the "id" and "PHPKITSID" parameters isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

5) Input passed to the "path" parameter in various scripts isn't
properly verified, before it is used to include files. This can be
exploited to include arbitrary files from local resources.

This can further be exploited to execute arbitrary PHP code injected
into an uploaded avatar image, but requires that the user is allowed
to upload custom avatar images.

6) Some unspecified input isn't properly sanitised before being used
in an "eval()" call. This can be exploited to inject and execute
arbitrary PHP code.

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities have been reported in version 1.6.1 R2 and prior.
Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified, and set "register_globals" to "Off".
