Common PrestaShop Vulnerabilities

Understanding the common vulnerabilities that affect PrestaShop is the first step in protecting your store. Here are some of the most prevalent threats:

• SQL Injection

  Description: SQL Injection vulnerabilities allow attackers to inject malicious SQL code into database queries, potentially granting them unauthorized access to sensitive data, including customer information, order details, and administrative credentials. This can lead to data theft, modification, or deletion.

  Severity: Critical

• Cross-Site Scripting (XSS)

  Description: XSS vulnerabilities enable attackers to inject malicious scripts into web pages viewed by other users. This can be used to steal cookies, redirect users to phishing sites, or deface the website.

  Severity: High

• Cross-Site Request Forgery (CSRF)

  Description: CSRF vulnerabilities allow attackers to trick users into performing actions they did not intend to, such as changing their password or making unauthorized purchases.

  Severity: Medium

• Remote File Inclusion (RFI)

  Description: RFI vulnerabilities allow attackers to include remote files on the server, potentially executing malicious code and gaining control of the system.

  Severity: Critical

• Local File Inclusion (LFI)

  Description: LFI vulnerabilities allow attackers to include local files on the server, potentially exposing sensitive information or executing malicious code.

  Severity: High

• Brute-Force Attacks

  Description: Brute-force attacks involve repeatedly trying different usernames and passwords to gain access to an account. Weak passwords make your store vulnerable to this type of attack.

  Severity: Medium

• Denial-of-Service (DoS) Attacks

  Description: DoS attacks flood the server with traffic, making it unavailable to legitimate users. This can disrupt your business and lead to lost sales.

  Severity: Medium

• Unvalidated Input

  Description: Failure to properly validate user input can lead to various vulnerabilities, including SQL Injection and XSS. Always sanitize and validate all user input before processing it.

  Severity: High
