Improper Control of Generation of Code in PrestaAddons - M4 PDF Extensions module for PrestaShop
In the module “M4 PDF Extensions” (m4pdf) up to version 3.3.2 from PrestaAddons for PrestaShop, a guest can perform PHP code injection in affected versions.
The method M4PDF::saveTemplate() has sensitive action that can be executed with a trivial http call and exploited to forge a Code injection.
Note : A useless predictable token protect these methods.
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.
WARNING : The module still own sensitive to critical issues because author refuse to update its logical authentication flaw, you should consider to delete it or put its front controller under IP restriction, if you do so, you must be aware of this.
Edit 2024-09-10 - WARNING : This exploit is actively used to deploy webskimmer to massively steal credit cards. Since POC is now exploited, it is considered public.
