Improper neutralization of SQL parameter in LeoTheme - Leo Blog module for PrestaShop
In the module “Leo Blog” (leoblog) up to version 3.1.2 from LeoTheme for PrestaShop, a guest can perform SQL injection in affected versions.
Methods LeoBlogBlog::getListBlogs, LeoBlogBlog::countBlogs, LeoBlogBlog::findByRewrite and Leoblogcat::findByRewrite have sensitive SQL calls that can be executed with a trivial http call and exploited to forge a SQL injection.
WARNING : This exploit is actively used to deploy a webskimmer to massively steal credit cards.
This exploit uses a PrestaShop front controller and most attackers can conceal the module controller’s path during the exploit, so you will never know within your conventional frontend logs that it exploits this vulnerability. You will only see “POST /” inside your conventional frontend logs. Activating the AuditEngine of mod_security (or similar) is the only way to get data to confirm this exploit.
