If you run an eCommerce store on PrestaShop, you’re probably aware that the latest version- PrestaShop was released on 25 July 2022.

This update is particularly significant because it fixes several critical security issues that could allow an unauthorized user to access or modify data on your site. If you’re running PrestaShop, we recommend upgrading to as soon as possible to take advantage of this security patch.

Like previous versions, this PrestaShop upgrade is recommended to keep your shop safe from attacks.
Let’s discuss more about it.

Where the Issue Lies?

PrestaShop Inc. has been powering eCommerce stores for years now. Unfortunately, some hostile performers exploit known and unknown security vulnerabilities to inject malicious code into PrestaShop websites, making them steal customers’ payment information.

Who are Under Attack?

  • PrestaShops that are vulnerable to SQL injection attacks.
  • Online eCommerce store using outdated software or modules.
  • PrestaShops that are using vulnerable third-party modules.

How Does the Attack Work?

Based on the conversations between the developers and the eCommerce owners, the systematic method of operation looks like this:

  • The attacker makes a POST request to the endpoint vulnerable to SQL injection.
  • A GET request to the homepage with no parameters is submitted within one second by the attacker. It results in a PHP file called blm.php at the root of the eCommerce directory.
  • Finally, the attacker submits a GET request to the new file, blm.php, allowing them to perform random activities.

Fake payment forms are injected into the front-office checkout page, and the customers fill their credit card information on the artificial form, unknowingly sending it to the attackers.

How to Keep Your Online Business Safe?

Update to the Latest PrestaShop Version

Ensure that your PrestaShop is operating on the latest version and that your modules are updated. Thus, preventing your eCommerce from being exposed to known and actively exploited SQL injection vulnerabilities.

Disable MySQL Smarty cache

To break the attack chain, physically disabling the MySQL Smarty cache storage feature in the PrestaShop code is recommended.

Perform Regular Checks

Your store requires regular checks and security scans to identify and eliminate potential malicious codes, viruses, hidden spam links, and spam pages. It is vital to remove all sources of vulnerabilities for strengthened security.

Update to Strong Passwords Regularly


It might seem trivial, but updating to strong store passwords regularly acts as the first line of defense against various forms of hacking. Mandating strong passwords will become one of the standard web features in 2023.

Ensure SSL Certificate Integration

SSL stands for secure socket layer, and as the name suggests, it offers an added layer of security to websites, web apps, mobile apps, and other software. A site with SSL offers data encryption between the web server and user communication. This helps to secure sensitive data like credit card details, customer personal information, username, passwords, etc. 

You can easily check whether your website has an SSL certificate or if you need to integrate one. Simply open the website over a browser. The website with SSL certificates showcases a green or black colored padlock icon in the address field right before the store address.

Bugs Fixed

  • Strengthens the MySQL Smarty cache storage against code injection attacks.
  • Security.
  • Eval injection if the shop is vulnerable to an SQL injection.

Reminder:  Keep your PrestaShop version updated to prevent such attacks. Don’t forget to regularly check for updates related to your PrestaShop software, modules, and server environment.
