VERIFY ADVISORY:
http://secunia.com/advisories/19116/

CRITICAL:
Highly critical

IMPACT:
Manipulation of data, Exposure of system information, Exposure of
sensitive information, System access

WHERE:
>From remote

SOFTWARE:
Php-Stats 0.x
http://secunia.com/product/8560/

DESCRIPTION:
rgod has reported some vulnerabilities and a security issue in
Php-Stats, which can be exploited by malicious people to conduct SQL
injection attacks, disclose system and sensitive information, and
compromise a vulnerable system.

1) Input passed to the "option[language]" and "option[template]"
parameters in "admin.php" isn't properly verified, before it is used
to include files. This can be exploited to include arbitrary files
from local resources.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

2) Input passed to the "option[prefix]" parameter in "admin.php" and
the "PC_REMOTE_ADDR" HTTP header in "click.php" isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

3) An input validation error in "admin.php" can be exploited to
inject arbitrary PHP code in "config.php".

4) The problem is that it is possible to disclose database table
prefixes by accessing the "checktables.php" script.

The vulnerabilities and the security issue have been reported in
version 0.1.9.1 and prior. Other versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
