Attack Tree Path: 1.1. Bypass Authentication/Authorization [HIGH-RISK]
Description: This is the most direct path to achieving the attacker's goal. It involves circumventing the application's authentication and authorization mechanisms to gain unauthorized access.
Attack Tree Path: 1.1.1. Exploit Misconfigured Filament Resources [HIGH-RISK]
Description: Filament Resources define how users interact with data. Misconfigurations here can expose data or functionality to unauthorized users.
Attack Tree Path: 1.1.1.1. Incorrectly Defined canViewAny, canView, canCreate, canEdit, canDelete methods (or missing authorization checks) [CRITICAL]
Attack Vector: The attacker attempts to access resources or perform actions without the required permissions. This is possible if the resource's authorization methods are incorrectly implemented (e.g., always returning true) or if authorization checks are missing entirely.
Example: A user without "edit" permissions on a "Posts" resource could still modify posts if the canEdit method always returns true.
Mitigation: Review all Filament Resource classes and ensure that the canViewAny, canView, canCreate, canEdit, and canDelete methods (and any other relevant authorization methods) correctly implement the intended access control logic. Use Filament's policy integration to centralize authorization logic. Thoroughly test each action with different user roles.
Attack Tree Path: 1.1.1.4. Exploiting Weaknesses in Custom Actions/Bulk Actions (if authorization is not properly enforced within the action's logic) [CRITICAL]
Attack Vector: The attacker triggers a custom action or bulk action that performs sensitive operations without proper authorization checks within the action's code. Even if the resource itself has authorization checks, the custom action might bypass them. Example: A custom action to "Delete All Users" might not check if the current user has the necessary permissions to perform this action. Mitigation: Ensure that all custom actions and bulk actions have explicit authorization checks within their execution logic. Do not rely solely on resource-level authorization.
Attack Tree Path: 1.1.2. Exploit Filament's User Impersonation Feature (if enabled and misconfigured)
Description: Filament's impersonation feature allows administrators to temporarily log in as another user. If misconfigured, this can be abused to gain unauthorized access.
Attack Tree Path: 1.1.2.1. Lack of Restrictions on Who Can Impersonate [CRITICAL]
Attack Vector: A user with lower privileges gains access to the impersonation feature and uses it to impersonate an administrator or another user with higher privileges. Example: A "moderator" user could impersonate an "administrator" user and gain full access to the system. Mitigation: Restrict the impersonation feature to specific, highly trusted users (e.g., super-administrators only). Implement robust logging of all impersonation events.
Attack Tree Path: 1.2. Exploit Filament's Form Builder
Attack Tree Path: 1.2.1. Cross-Site Scripting (XSS) via Unsanitized Input in Custom Form Fields [HIGH-RISK]
Description: XSS vulnerabilities allow attackers to inject malicious JavaScript code into the application, which is then executed in the browsers of other users.
Attack Tree Path: 1.2.1.1. Insufficient Input Validation/Sanitization in Custom Field Types [CRITICAL]
Attack Vector: The attacker submits a form containing malicious JavaScript code in a custom form field. If the application does not properly sanitize this input before rendering it in the view, the code will be executed.
Example: A custom "Rich Text Editor" field might not properly sanitize HTML tags, allowing an attacker to inject <script> tags containing malicious code.
Mitigation: Ensure that all custom form field types properly sanitize user input before rendering it in the view. Use Laravel's built-in escaping mechanisms (e.g., {{ }} in Blade templates). Thoroughly test with various XSS payloads.
Description: IDOR vulnerabilities allow attackers to access or modify data they should not have access to by manipulating identifiers (e.g., record IDs) in form submissions.
Attack Tree Path: 1.2.2.1. Lack of Authorization Checks When Handling Form Data (e.g., allowing a user to modify a record they don't own by manipulating form data) [CRITICAL]
Attack Vector: The attacker submits a form, modifying the ID of a record to one they do not own. If the application does not properly check authorization when handling the form data, the attacker can modify or delete the record.
Example: A user editing their profile might change the user_id in the form data to that of another user and modify their profile information.
Mitigation: Implement robust authorization checks within the form submission handling logic (e.g., in the Resource's form method or in a dedicated Form Request). Verify that the current user has permission to access or modify the specific record being processed. Do not rely solely on Filament's resource-level authorization.
Attack Tree Path: 1.2.3. File Upload Vulnerabilities (if Filament's file upload component is misconfigured or vulnerable) [HIGH-RISK]
Description: File upload vulnerabilities can allow attackers to upload malicious files to the server, potentially leading to remote code execution.
Attack Tree Path: 1.2.3.1. Lack of File Type Validation (allowing upload of malicious files, e.g., PHP scripts) [CRITICAL]
Attack Vector: The attacker uploads a file with a malicious extension (e.g., .php, .phtml, .phar) that can be executed by the server.
Example: An attacker uploads a PHP script disguised as an image file. If the server executes this script, the attacker gains control of the application.
Mitigation: Implement strict file type validation, preferably using a whitelist approach (allow only specific, safe file types). Validate both the file extension and the MIME type. Do not rely solely on the file extension for validation.
Attack Tree Path: 1.3. Exploit Filament's Table Builder
Attack Tree Path: 1.3.1. XSS via Unsanitized Data Displayed in Tables [HIGH-RISK]
Description: Similar to XSS in form fields, this involves injecting malicious code into data displayed in tables.
Attack Vector: The attacker injects malicious JavaScript into data that is later displayed in a table. If a custom column renderer does not properly escape this data, the script will execute.
Example: If a table displays user comments, and a custom column renderer is used to format these comments, an attacker could inject a <script> tag into a comment.
Mitigation: Ensure that all custom column renderers properly escape data before displaying it in the table. Use Laravel's Blade escaping syntax ({{ }}).
Attack Tree Path: 2. Exploit Vulnerabilities in Third-Party Filament Plugins [HIGH-RISK]
Description: Third-party plugins can introduce vulnerabilities if they are not properly vetted, updated, or configured.
Attack Tree Path: 2.2. Exploit Known Vulnerabilities in Plugins [CRITICAL]
Attack Vector: The attacker identifies a known vulnerability in a plugin used by the application and exploits it. Example: A plugin might have a known SQL injection vulnerability. The attacker uses this vulnerability to gain access to the database. Mitigation: Keep all plugins updated to the latest versions. Monitor security advisories for plugins and apply patches promptly. Carefully vet plugins before installing them, and consider the security implications of using third-party code.
Attack Tree Path: 3. Dependency Vulnerabilities (Indirectly related to Filament)
Attack Tree Path: 3.1. Vulnerabilities in Filament's Dependencies (e.g., Laravel, Livewire, Alpine.js) [HIGH-RISK]
Description: Vulnerabilities in Filament's dependencies (Laravel, Livewire, Alpine.js, etc.) can be exploited to compromise the application.
Attack Vector: The attacker exploits a known vulnerability in a dependency.
Example: A vulnerability in Laravel's routing component could be exploited to bypass authentication.
Mitigation: Keep all dependencies updated to the latest versions. Use a dependency vulnerability scanner (e.g., composer audit, Snyk, Dependabot) to identify and remediate known vulnerabilities.
