| Vulnerable Software: TemplateMonster osCommerce |
| Vendor: http://templatemonster.org |
| Vulnerability Type: Error-based SQL Injection |
| Date Released: 23/04/2017 |
| Released by: Project Insecurity (@insecurity)|
[+]---------------------------------------------------------[+]
TemplateMonster is a site that makes templates for various content management systems. There are severe SQL injection
issues in their template for popular CMS 'osCommerce' - this can lead to a complete system compromise of any site using this
template. Estimated around 70k-100k vulnerable sites although not that many are indexed on google.
This source apears to be a developer from templatemonster releasing source code publicly instead of forcing users to pay for it.
The source is vulnerable to SQL INJECTION in the tag_products.php file:
https://github.com/templatemonster/oscommerce/blob/master/theme/tag_products.php
The code for this file can be seen below:
-------------------------------------------------------------------------------------------------------------
$tag_id= $HTTP_GET_VARS['id_tag'];
$tag_text="";
$tags_query = tep_db_query("select * from ". TABLE_TAGS ." where tag_id='". $tag_id ."'");
while ($tags_result = tep_db_fetch_array($tags_query)) {
$tag_text = urldecode($tags_result['tag_text']);
}
-------------------------------------------------------------------------------------------------------------
As you can see above, it does not escape the SQL statement and accepts any value for the id_tag GET param
Basic PoC of how exploitation would take place using SQLMap + cURL (and html2text for sorting):

Public Vulnerability that can be used in conjunction to this exploit:
https://www.exploit-db.com/exploits/31515/
Once the credentials have been stolen and an attacker has logged into the admin panel they can run union based SQL injection queries
and thus be able to steal the database faster and be able to read files and/or input into files causing complete system compromise.
http://[HOST]/admin/geo_zones.php?action=list&zID=1 group by 1 union select 1,2,3,4,5,6,7,concat(user_name,0x3a,user_password) from administrators --
Btw, we will write an actual PoC for this that can be ran as a python or bash script if any of you guys are interested :)
For both of these exploits (0day + public vuln) used in conjunction with eacohter. Let us know if there's any appeal for that.
-------------------------------------------------------------------------------------------------------------
How to fix: properly escape SQL queries / sanatize user inputs.. no response from vendor after months and months of effort. Despite
MANY websites being vulnerable. Some vuln site admins contacted, seemed panicked (and rightfully so)
