The flaw is an improper input validation vulnerability that could be exploited by threat actors with administrative privileges to achieve arbitrary code execution on vulnerable systems.

Now a new wave of attacks targeting the Magento 2 vulnerability, three types of attack detailed by researchers.

The first attack pattern starts by creating a new customer account and an order placement on the vulnerable system. The attackers use a malicious template code in the first and last names and to place the order.

On execution, the code downloads a Linux executable called “223sam.jpg” and launches it as a background process called cli, which is a RAT. The malware run in memory and creates a state file lg000, then polls a remote server hosted in Bulgaria for commands.

Second variant of the attack injects the health_check.php backdoor. The attacker injects the placed order containing a specific template code in the VAT field. The code creates a the file “pub/media/health_check.php” that accepts commands via POST requests.

A third attack variation of the attack replaces generated/code/Magento/Framework/App/FrontController/Interceptor.php with a tainted version.
