Mitigation Strategies Analysis for prestashop/prestashop

Mitigation Strategy: Strictly Control Module and Theme Sources (PrestaShop Ecosystem)

  • Description:

    1. Utilize PrestaShop Addons Marketplace as primary source: Prioritize modules and themes from the official PrestaShop Addons Marketplace due to their review process (though not foolproof, it offers a baseline of scrutiny).
    2. Vet developers outside Marketplace: If using modules/themes from outside the Marketplace, thoroughly vet the developer's reputation, security track record, and community feedback. Check for developer profiles on PrestaShop forums or communities.
    3. Disable non-essential module sources: If PrestaShop configuration allows, restrict module installation to specific sources or require administrator approval for installations from unknown sources.
    4. Leverage PrestaShop's module manager for updates: Utilize the PrestaShop module manager to check for updates from the Addons Marketplace and trusted developers.
    5. Educate users on PrestaShop module risks: Train administrators and developers about the inherent risks of installing modules and themes, especially from untrusted sources within the PrestaShop ecosystem.

  • Threats Mitigated:

    • Malware Injection via Modules/Themes (High Severity): Malicious code embedded within PrestaShop modules or themes from untrusted sources.
    • Backdoors in Modules/Themes (High Severity): Hidden backdoors introduced through compromised or malicious PrestaShop modules/themes.
    • Vulnerabilities in Third-Party PrestaShop Extensions (High/Medium Severity): Security flaws in modules and themes due to poor coding practices or lack of security awareness by developers within the PrestaShop ecosystem.

  • Impact:

    • Malware Injection via Modules/Themes: High risk reduction. Significantly reduces the chance of installing malware by focusing on trusted PrestaShop sources.
    • Backdoors in Modules/Themes: High risk reduction. Makes it harder for attackers to introduce backdoors through PrestaShop extensions.
    • Vulnerabilities in Third-Party PrestaShop Extensions: Medium to High risk reduction. Reduces exposure to vulnerabilities from less reputable developers in the PrestaShop ecosystem, but vetting is still crucial.

  • Currently Implemented:

    • Partially implemented. We generally prefer modules from the official marketplace, but there isn't a formal policy or enforced blocking of other sources. Vetting of external developers is inconsistent.

  • Missing Implementation:

    • Formal policy document for PrestaShop module/theme sourcing.
    • Technical controls within PrestaShop or server-level to restrict module sources.
    • Mandatory vetting process for developers outside the PrestaShop Addons Marketplace.

Mitigation Strategy: Regularly Update Modules and Themes (PrestaShop Update Mechanism)

  • Description:

    1. Utilize PrestaShop's module update notifications: Regularly check the PrestaShop admin panel for module and theme update notifications.
    2. Subscribe to PrestaShop security channels: Monitor PrestaShop's official security blog, newsletters, and social media for announcements regarding core, module, and theme security updates.
    3. Test updates in PrestaShop staging environment: Always test module and theme updates in a dedicated PrestaShop staging environment that mirrors the production setup before applying them to the live store.
    4. Prioritize PrestaShop security updates: Treat security updates for PrestaShop core, modules, and themes as critical and apply them promptly.
    5. Document PrestaShop update procedures: Create and maintain documented procedures specifically for updating PrestaShop core, modules, and themes, including rollback steps within the PrestaShop environment.

  • Threats Mitigated:

    • Exploitation of Known PrestaShop Module/Theme Vulnerabilities (High Severity): Attackers targeting publicly disclosed vulnerabilities in outdated PrestaShop modules and themes.
    • Compromise through Outdated PrestaShop Extensions (High Severity): Exploiting vulnerabilities in older versions of PrestaShop modules and themes to gain control of the store.

  • Impact:

    • Exploitation of Known PrestaShop Module/Theme Vulnerabilities: High risk reduction. Significantly reduces the risk of attacks targeting known flaws in PrestaShop extensions.
    • Compromise through Outdated PrestaShop Extensions: High risk reduction. Keeps the PrestaShop environment secure against exploits targeting older module/theme versions.

  • Currently Implemented:

    • Partially implemented. We attempt to update modules and themes periodically, but it's not on a strict schedule. Testing in staging is sometimes skipped for minor PrestaShop extension updates. Security updates are not always prioritized within PrestaShop update cycles.

  • Missing Implementation:

    • Formal update schedule and documented process specifically for PrestaShop updates.
    • Automated or semi-automated system to track PrestaShop module/theme updates.
    • Strict process for prioritizing and rapidly deploying security updates within the PrestaShop update workflow.
    • Consistent use of a PrestaShop staging environment for testing all updates.

Mitigation Strategy: Secure the Administration Directory (PrestaShop Admin Panel)

  • Description:

    1. Rename PrestaShop's default admin folder: During PrestaShop installation or post-installation, rename the default /admin directory to a unique, less predictable name using PrestaShop's configuration or manual file system operations.
    2. Implement IP whitelisting for PrestaShop admin access: Configure web server or firewall rules to restrict access to the renamed PrestaShop administration directory to only authorized IP addresses or IP ranges.
    3. Enable Two-Factor Authentication (2FA) in PrestaShop: Activate PrestaShop's built-in 2FA feature or use a compatible module for administrator accounts.
    4. Utilize PrestaShop's security settings: Explore and configure security-related settings within the PrestaShop admin panel, such as password policies and session management.
    5. Regularly audit PrestaShop admin user accounts: Review administrator accounts within PrestaShop periodically and remove or disable unnecessary accounts. Enforce strong password policies using PrestaShop's password management features.

  • Threats Mitigated:

    • Brute-Force Attacks on PrestaShop Admin Login (High Severity): Attackers attempting to guess administrator credentials to access the PrestaShop backend.
    • Credential Stuffing against PrestaShop Admin Panel (High Severity): Using compromised credentials to log in to the PrestaShop admin panel.
    • Unauthorized Access to PrestaShop Administration (High Severity): Gaining unauthorized access to control the PrestaShop store and its data.

  • Impact:

    • Brute-Force Attacks on PrestaShop Admin Login: High risk reduction. Renaming admin directory and IP whitelisting significantly reduces the attack surface targeting the PrestaShop admin panel. 2FA adds strong protection.
    • Credential Stuffing against PrestaShop Admin Panel: High risk reduction. 2FA effectively mitigates credential stuffing attempts against PrestaShop admin accounts.
    • Unauthorized Access to PrestaShop Administration: High risk reduction. Combined measures make unauthorized access to the PrestaShop backend significantly harder.

  • Currently Implemented:

    • Partially implemented. We have renamed the admin directory. IP whitelisting for PrestaShop admin is considered but not consistently applied. 2FA is encouraged but not mandatory for all PrestaShop admin accounts.

  • Missing Implementation:

    • Mandatory 2FA for all PrestaShop administrator accounts.
    • Formal IP whitelisting rules and enforcement specifically for PrestaShop admin access.
    • Leveraging PrestaShop's built-in security settings more comprehensively.
    • Regular audits of PrestaShop admin user accounts and password policies within the PrestaShop user management system.

Mitigation Strategy: Disable Debug Mode in Production (PrestaShop Configuration)

  • Description:

    1. Modify PrestaShop's _PS_MODE_DEV_ constant: In the config/defines.inc.php file of your PrestaShop installation, explicitly set define('_PS_MODE_DEV_', false); for the production environment. This is a core PrestaShop configuration setting.
    2. Review PrestaShop error reporting settings: Check error reporting configuration within PrestaShop's admin panel (if available) or directly in config/defines.inc.php and PHP configuration. Ensure error reporting is minimized in production to avoid exposing sensitive PrestaShop details.
    3. Utilize PrestaShop environment variables: If deploying in different environments, use PrestaShop's environment variable capabilities (if available in your PrestaShop version) to manage debug mode and other environment-specific settings.
    4. Document PrestaShop environment configurations: Clearly document the intended configuration for each PrestaShop environment (development, staging, production), especially regarding debug mode.

  • Threats Mitigated:

    • Information Disclosure via PrestaShop Debug Output (Medium Severity): Debug mode in PrestaShop can reveal sensitive configuration details, database credentials, and code paths in error messages.
    • PrestaShop Specific Information Leakage (Low Severity): Debug mode might expose PrestaShop version information or internal workings that could be helpful to attackers targeting PrestaShop specifically.

  • Impact:

    • Information Disclosure via PrestaShop Debug Output: Medium risk reduction. Prevents accidental exposure of sensitive PrestaShop configuration and internal details through debug mode errors.
    • PrestaShop Specific Information Leakage: Low risk reduction. Minimizes information leakage that could aid attackers in targeting the PrestaShop platform.

  • Currently Implemented:

    • Likely implemented. Debug mode is generally disabled in production PrestaShop environments as a standard practice. However, explicit verification of the _PS_MODE_DEV_ setting in defines.inc.php is needed.

  • Missing Implementation:

    • Automated configuration management for PrestaShop environment settings, including debug mode.
    • Regular automated checks to verify _PS_MODE_DEV_ is set to false in production PrestaShop instances.
    • Clear documentation specifically for PrestaShop developers regarding debug mode settings in different environments.
