Threat Model Analysis for z-song/laravel-admin

Threat: Privilege Escalation via Extension Vulnerability

  • Threat: Privilege Escalation via Extension Vulnerability

    • Description: An attacker exploits a vulnerability in a third-party or custom laravel-admin extension. The attacker might upload a malicious extension, or exploit a vulnerability in an existing extension (e.g., a file upload vulnerability, an insecure direct object reference, or a code injection flaw) to execute arbitrary code with the privileges of the web server user. This could allow them to bypass laravel-admin's RBAC and gain full administrative access.
    • Impact: Complete compromise of the application and potentially the underlying server. The attacker could read, modify, or delete any data, install malware, or use the server for other malicious purposes.
    • Affected Component: laravel-admin Extensions (specifically, vulnerable third-party or custom extensions). This could affect any extension that handles user input, file uploads, or interacts with the database or filesystem. The Admin::extend() function and the extension loading mechanism are potential attack vectors.
    • Risk Severity: Critical
    • Mitigation Strategies:
      • Vetting: Thoroughly vet all third-party extensions before installation. Examine the code for potential vulnerabilities, check the developer's reputation, and review user feedback.
      • Updates: Keep all extensions updated to the latest versions to patch known vulnerabilities.
      • Least Privilege: Run the web server with the least privileges necessary. Avoid running as root.
      • Code Review: Perform code reviews of all custom extensions, paying close attention to security best practices.
      • Input Validation: Implement strict input validation and output encoding in all custom extensions.
      • File Upload Restrictions: If file uploads are allowed, restrict file types, sizes, and upload locations. Scan uploaded files for malware.
      • Security Audits: Regularly conduct security audits and penetration testing, focusing on extensions.

Threat: Weak Authentication to Laravel-Admin

  • Threat: Weak Authentication to Laravel-Admin

    • Description: An attacker uses brute-force, credential stuffing, or password guessing attacks to gain access to a laravel-admin user account. This is due to weak password policies, lack of multi-factor authentication, or the use of default credentials. This directly impacts laravel-admin because it manages its own authentication system.
    • Impact: Unauthorized access to the laravel-admin interface, potentially leading to data breaches, system compromise, or other malicious activities.
    • Affected Component: laravel-admin Authentication (specifically, the login form, user model, and authentication logic). The config/admin.php auth settings are relevant.
    • Risk Severity: High
    • Mitigation Strategies:
      • Strong Passwords: Enforce strong password policies, requiring a minimum length, complexity (uppercase, lowercase, numbers, symbols), and regular password changes.
      • Multi-Factor Authentication (MFA): Implement MFA for all laravel-admin users.
      • Account Lockout: Implement account lockout policies to prevent brute-force attacks.
      • No Default Credentials: Change default laravel-admin credentials immediately after installation.
      • Rate Limiting (Login): Implement rate limiting on the login route to prevent rapid login attempts.

Threat: Configuration Tampering via config/admin.php or Extension Configs (Direct File Access if Web Server Misconfigured)

  • Threat: Configuration Tampering via config/admin.php or Extension Configs (Direct File Access if Web Server Misconfigured)

    • Description: While ideally file system access is a server-level concern, if the web server is misconfigured to allow direct access to files within the vendor/encore/laravel-admin or config/ directory, an attacker could directly modify laravel-admin's core configuration or extension configurations. This is a direct threat to laravel-admin if the underlying server security is insufficient. The attacker could change authentication settings, disable security features, or inject malicious code.
    • Impact: Bypass of authentication, gain of administrative access, exposure of sensitive information, or disruption of application functionality. The severity depends on the specific configuration changes.
    • Affected Component: laravel-admin Configuration Files (specifically, config/admin.php and any configuration files related to installed extensions). The Admin::config() function and how configuration is loaded are relevant.
    • Risk Severity: High (conditional on server misconfiguration, but directly impacts laravel-admin)
    • Mitigation Strategies:
      • Web Server Configuration: Crucially, ensure the web server (Apache, Nginx) is configured to prevent direct access to the vendor/ and config/ directories. This is the primary mitigation.
      • File System Permissions: Implement strict file system permissions. The web server user should have minimal write access to configuration files.
      • Version Control: Use a version control system (e.g., Git) to track changes to configuration files.
      • File Integrity Monitoring: Use a file integrity monitoring (FIM) system to detect unauthorized changes.
      • Environment Variables: Store sensitive configuration values (e.g., API keys, database credentials) in environment variables, not directly in configuration files.
