PHPKIT userinfo.php SQL Injection
------------------------------------------------------------------------
SUMMARY
<http://www.phpkit.de/>; PHPKIT is "a modular developed homepage software
which enables simple management messages contents, guest book, forums and
more".
Due to improper sanity validation checks in PHPKIT's login/userinfo.php it
is possible for an attacker to manipulate an SQL query.
DETAILS
Vulnerable Systems:
* PHPKIT version 1.6.1 and prior
Vulnerable code:
In the file login/userinfo.php, the following line can be found:
$userinfo=$DB->fetch_array($DB->query("SELECT * FROM ".$db_tab['user']."
where user_id='".$id."' LIMIT 1"));
This SQL statement's $id parameter is not filtered properly.
Examples:
http://127.0.0.1/phpkit/include.php?path=login/userinfo.php&id=1' and
1=2/*
http://127.0.0.1/phpkit/include.php?path=login/userinfo.php&id=1' user_pw
like char(37)/*
Unofficial Patch:
Change
$userinfo=$DB->fetch_array($DB->query("SELECT * FROM ".$db_tab['user']."
where user_id='".$id."' LIMIT 1"));
to
$userinfo=$DB->fetch_array($DB->query("SELECT * FROM ".$db_tab['user']."
where user_id='".addslahes($id)."' LIMIT 1"));
