- Summary
- OpenMage LTS has Customer File Upload Extension Blocklist Bypass that Leads to Remote Code Execution
- Details
-
Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. Prior to version 20.17.0, the product custom option file upload in OpenMage LTS uses an incomplete blocklist (
forbidden_extensions = php,exe) to prevent dangerous file uploads. This blocklist can be trivially bypassed by using alternative PHP-executable extensions such as.phtml,.phar,.php3,.php4,.php5,.php7, and.pht. Files are stored in the publicly accessiblemedia/custom_options/quote/directory, which lacks server-side execution restrictions for some configurations, enabling Remote Code Execution if this directory is not explicitly denied script execution. Version 20.17.0 patches the issue. - Database specific
