Threat Model Analysis for nopsolutions/nopcommerce

Threat: Malicious Plugin Installation

  • Description: An attacker convinces an administrator to install a plugin from an untrusted source. The plugin contains malicious code (backdoor, malware, data exfiltration). The attacker might use social engineering or compromised marketplaces to distribute the malicious plugin.
  • Impact: Full system compromise, data breach (customer data, order data, admin credentials), reputational damage, financial loss.
  • Affected Component: Plugin System, Core Application
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Developers/Users: Only install plugins from the official nopCommerce marketplace or reputable, verified developers.
    • Developers/Users: Implement a plugin review process before installation, including code analysis if feasible.
    • Users: Regularly audit installed plugins and remove any unused or suspicious ones.
    • Users: Implement strong access control to the administration panel to limit who can install plugins.

Threat: Vulnerable Plugin Exploitation

  • Description: An attacker identifies and exploits a known or zero-day vulnerability in a poorly coded or outdated nopCommerce plugin. This could be through publicly disclosed vulnerabilities or by reverse engineering the plugin. Exploits could range from XSS to SQL Injection or Remote Code Execution.
  • Impact: Depending on the vulnerability, impacts can range from data theft, website defacement, session hijacking (XSS), to full system compromise (RCE, SQL Injection leading to OS command execution).
  • Affected Component: Plugin System, Specific Vulnerable Plugin

    • Users: Implement strong password policies (complexity, length, rotation).
    • Users: Regularly audit and rotate administrator credentials.
    • Users: Consider using multi-factor authentication (MFA) for administrator accounts.

Threat: Insecure Database Connection Strings

  • Description: Database connection strings are stored in easily accessible configuration files (e.g., appsettings.json) or with weak credentials. An attacker gaining access to the server or configuration files can retrieve these credentials and access the database directly.
  • Impact: Data breach (customer data, order data, admin credentials), data manipulation, denial of service by database compromise, potential for privilege escalation if database user has excessive permissions.
  • Affected Component: Configuration System, Data Access Layer
  • Risk Severity: High
  • Mitigation Strategies:
    • Developers/Users: Securely store database connection strings, avoid storing them in plain text in configuration files.
    • Developers/Users: Use environment variables or dedicated secret management solutions (e.g., Azure Key Vault, HashiCorp Vault) to store connection strings.
    • Users: Use least privilege database accounts for nopCommerce application.
    • Users: Restrict access to configuration files and the server itself.

Threat: Exposed Administration Panel

  • Description: The nopCommerce administration panel is publicly accessible without proper access controls. Attackers can attempt brute-force attacks, credential stuffing, or exploit vulnerabilities in the admin login process.
  • Impact: Unauthorized access to the administration panel, full compromise of the application, data breach, manipulation of store settings, financial fraud.
  • Affected Component: Administration Panel, Authentication System
  • Risk Severity: High
  • Mitigation Strategies:
    • Users: Implement IP address restrictions or VPN access to the administration panel.
    • Users: Use strong authentication mechanisms like multi-factor authentication (MFA) for admin logins.
    • Users: Consider renaming the default admin path to make it less easily discoverable (security through obscurity, not a primary security measure).
    • Users: Implement rate limiting and account lockout policies to mitigate brute-force attacks.

Threat: Misconfigured Access Control Lists (ACLs)

  • Description: Incorrectly configured ACLs within nopCommerce grant users or roles excessive permissions, allowing unauthorized access to sensitive features, data, or administrative functions. This could be due to misconfiguration during setup or changes made by administrators without proper understanding.
  • Impact: Privilege escalation, unauthorized access to customer data, order manipulation, administrative functions, potential for data breaches and financial fraud.
  • Affected Component: Access Control System, Role Management
  • Risk Severity: High (in scenarios leading to significant privilege escalation or data access)
  • Mitigation Strategies:
    • Users: Regularly review and audit ACL configurations.
    • Users: Follow the principle of least privilege when assigning roles and permissions.
    • Users: Provide training to administrators on proper ACL configuration and role management.
    • Users: Implement a process for reviewing and approving changes to ACLs.
