Threat Model Analysis for filamentphp/filament

Threat: Insufficient Role-Based Access Control (RBAC) Configuration

• Description: Attacker exploits misconfigured Filament permissions to access unauthorized resources or functionalities within the admin panel. This is achieved by circumventing intended access restrictions defined in Filament's permission system.
• Impact: Unauthorized access to sensitive data and administrative functionalities, leading to data breaches, data manipulation, and potential system compromise.
• Filament Component Affected: Filament Permission System, Policies, Resources, Actions, Pages.
• Risk Severity: High
• Mitigation Strategies:
  • Implement granular Filament permissions based on the principle of least privilege.
  • Thoroughly review and test Filament permission configurations, especially for sensitive resources and actions.
  • Utilize Filament's permission testing features to validate access control rules.
  • Regularly audit and update Filament permission settings as roles and responsibilities evolve.

Threat: Vulnerabilities in Filament's Authentication Logic

• Description: Attacker exploits security vulnerabilities within Filament's core authentication mechanisms to bypass login and gain unauthorized access to the admin panel. This could involve flaws in Filament's authentication middleware or login process.
• Impact: Complete bypass of Filament authentication, granting full administrative access and potentially compromising the entire application and its data.
• Filament Component Affected: Filament Authentication Middleware, Login Functionality.
• Risk Severity: Critical
• Mitigation Strategies:
  • Keep Filament updated to the latest version to benefit from security patches and bug fixes.
  • Monitor Filament security advisories and apply updates promptly.
  • Conduct security audits and penetration testing specifically targeting Filament's authentication implementation.

Threat: Session Hijacking/Fixation related to Filament's Session Handling

• Description: Attacker attempts to steal or fixate user sessions to gain unauthorized access to the Filament admin panel. This can be achieved through network sniffing or cross-site scripting (XSS) if session handling within the Filament context is not properly secured.
• Impact: Unauthorized access to administrator accounts, allowing attackers to perform administrative actions, leading to data breaches, data manipulation, and system compromise.
• Filament Component Affected: Filament's integration with Laravel Session Management, potentially Filament's login and logout flows.
• Risk Severity: High
• Mitigation Strategies:
  • Configure secure session settings in Laravel, ensuring secure and httpOnly flags are set for session cookies.
  • Enforce HTTPS for all Filament admin panel traffic to protect session cookies in transit.
  • Implement robust XSS prevention measures (see XSS threats below) to minimize session cookie theft risks.

Threat: Insecure Direct Object References (IDOR) in Filament Resource Actions

• Description: Attacker manipulates resource IDs in URLs to access or modify Filament resources they are not authorized to interact with. This is possible if authorization checks are insufficient in Filament resource actions (edit, delete, view).
• Impact: Unauthorized access, modification, or deletion of Filament managed data, potentially leading to data breaches, data corruption, and privilege escalation within the admin panel.
• Filament Component Affected: Filament Resources, Resource Actions (Edit, Delete, View), Routing within Filament.
• Risk Severity: High
• Mitigation Strategies:
  • Implement robust authorization checks within Filament resource actions, leveraging Filament's policies and permission system.
  • Ensure that resource actions always verify user permissions based on the specific resource being accessed.
  • Avoid directly exposing predictable internal IDs in URLs; consider using UUIDs or other less guessable identifiers where appropriate.

Threat: XSS in Filament Form Field Rendering

• Description: Attacker injects malicious JavaScript code into Filament form fields. This code is then executed in the browsers of administrators when the form is rendered within the Filament admin panel.
• Impact: Account compromise of administrators, session hijacking, defacement of the Filament admin panel, and potential further attacks on the backend system.
• Filament Component Affected: Filament Forms, Form Field Rendering, Blade Templates used by Filament.
• Risk Severity: High
• Mitigation Strategies:
  • Rely on Filament's built-in form field components, which are designed to be XSS-safe.
  • If using custom form fields, ensure all user-provided data is properly sanitized and escaped during rendering within Filament views.
  • Implement Content Security Policy (CSP) headers for the Filament admin panel to further mitigate XSS risks.

Threat: XSS in Filament Table Columns and Filters

• Description: Attacker injects malicious JavaScript code into data displayed in Filament tables or used in table filters. This code executes when administrators view tables or interact with filters within the Filament admin panel.
• Impact: Account compromise of administrators, session hijacking, defacement of the Filament admin panel, and potential further attacks on the backend system.
• Filament Component Affected: Filament Tables, Table Column Rendering, Table Filters, Blade Templates used by Filament.
• Risk Severity: High
• Mitigation Strategies:
  • Utilize Filament's built-in table components, which are generally designed to be XSS-safe.
  • If using custom table columns or filters, ensure all data rendered in tables is properly sanitized and escaped within Filament views.
  • Implement Content Security Policy (CSP) headers for the Filament admin panel to further mitigate XSS risks.

Threat: Exploiting RBAC Misconfigurations for Privilege Escalation

• Description: Attacker leverages misconfigured Filament RBAC rules to gain higher privileges within the Filament admin panel than initially intended. This can be achieved by exploiting flaws in permission logic or manipulating roles if user management within Filament is insecure.
• Impact: Privilege escalation, allowing attackers to gain administrative access from a lower-privileged account, leading to full control over the Filament admin panel and potentially the entire application.
• Filament Component Affected: Filament Permission System, Policies, User Management features within Filament.
• Risk Severity: Critical
• Mitigation Strategies:
  • Thoroughly test and validate Filament RBAC configurations to prevent unintended privilege escalation paths.
  • Implement robust permission checks and validation logic within Filament's permission system.
  • Restrict access to Filament's user and role management features to only highly trusted administrators.
  • Regularly audit Filament user roles and permissions to identify and rectify any misconfigurations.

Threat: Abuse of Filament Features for Privilege Escalation

• Description: Attacker abuses legitimate Filament features, particularly those related to user or role management within Filament itself, to escalate their privileges. This could involve exploiting vulnerabilities in these features or misusing them in unintended ways to gain administrative access.
• Impact: Privilege escalation, granting attackers administrative control over the Filament admin panel and potentially the entire application by misusing intended Filament functionalities.
• Filament Component Affected: Filament User Management Features, Role Management Features, Custom Filament features related to user roles and permissions.
• Risk Severity: High to Critical
• Mitigation Strategies:
  • Carefully design and secure user and role management features implemented within Filament.
  • Implement strict authorization checks for all user and role management actions within Filament.
  • Audit Filament's user and role management features for potential abuse scenarios and unintended privilege escalation paths.
  • Limit access to sensitive Filament features, especially user and role management, to only highly privileged administrators.
