VERIFY ADVISORY:
http://secunia.com/advisories/20201/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
DGBook 1.x

DESCRIPTION:
Some vulnerabilities have been discovered in DGBook, which can be
exploited by malicious people to conduct script insertion attacks and
SQL injection attacks.

1) Input passed to the "name", "email", "homepage", "address",
"comment", and "ip" 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.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

2) Input passed to the "name", "homepage", "email", and "address"
parameters in index.php is not properly sanitised before being used.
This can be exploited to insert arbitrary HTML and script code, which
will be executed in a user's browser session in context of an affected
site when malicious data is viewed.

The vulnerabilities have been confirmed in version 1.0. Other
versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
1) Reported by an anonymous person.
2) luny
