TITLE:
VBook Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA19448

VERIFY ADVISORY:
http://secunia.com/advisories/19448/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
VBook 2.x
http://secunia.com/product/9051/

DESCRIPTION:
Aliaksandr Hartsuyeu has discovered multiple vulnerabilities in
VBook, which can be exploited by malicious people to conduct script
insertion attacks and SQL injection attacks, and by malicious users
to compromise a vulnerable system.

1) Input passed to the "autor", "email", "www", "temat", and "tresc"
parameters is not properly sanitised before being used. This can be
exploited to inject arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
when malicious content is viewed.

2) Input passed to the "x" paramter 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.

3) Input passed to configuration parameters in "admin.php" is not
properly sanitised before being stored in "config.php". This can be
exploited to inject arbitrary PHP code, which is executed when
"config.php" is used. Access to the administration section is
required.

Note that the administration password is stored in a cookie.

Successful exploitation requires "magic_quotes_gpc" to be disabled.

The vulnerabilities have been confirmed in version 2.0. Other
versions may also be affected.

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