Mitigation Strategy: Thorough Configuration Review and Hardening (Voyager-Specific)

  • Description:

    1. Voyager Configuration Files: Focus specifically on config/voyager.php and any BREAD-specific configuration files.
    2. Feature Disablement: Disable Voyager-specific features that are not absolutely necessary. This includes:
      • The built-in media manager (if not used or if a more secure alternative is implemented).
      • Specific BREAD operations (add, edit, delete, read, browse) on a per-table basis. If a table should only be viewable, disable "add," "edit," and "delete."
      • Unused dashboard widgets or menu items.
      • The database manager (if direct database access through Voyager is not required).
      • Voyager's built-in documentation links (if not needed).
    3. Voyager Role and Permission Review: Examine and meticulously configure Voyager's role and permission system. Create granular roles with the least privilege necessary. Avoid relying solely on the default "admin" role. Test permissions extensively by logging in as users with different roles.
    4. Voyager View Customization: Inspect and customize Voyager's Blade templates (resources/views/vendor/voyager). Remove any potential exposure of sensitive data within these views. Ensure proper output encoding to prevent XSS vulnerabilities within the Voyager interface itself.
    5. Regular Voyager-Specific Review: Schedule periodic reviews (e.g., every 3-6 months) focused solely on the Voyager configuration and its security implications.

  • Threats Mitigated:

    • Over-reliance on Voyager Defaults (Severity: High): Reduces the attack surface by disabling unnecessary Voyager features.
    • Unauthorized Access (Voyager-Specific) (Severity: High): Ensures users can only access Voyager functionalities according to their assigned roles.
    • Information Disclosure (Voyager-Specific) (Severity: Medium-High): Prevents sensitive data exposure through Voyager's interface.
    • Privilege Escalation (Voyager-Specific) (Severity: High): Limits the potential for users to gain unauthorized privileges within Voyager.

  • Impact:

    • Over-reliance on Voyager Defaults: Significantly reduces risk.
    • Unauthorized Access (Voyager-Specific): High impact; prevents unauthorized actions within Voyager.
    • Information Disclosure (Voyager-Specific): Medium-high impact; reduces data leaks within Voyager.
    • Privilege Escalation (Voyager-Specific): High impact; prevents privilege escalation within Voyager.

  • Currently Implemented:

    • config/voyager.php reviewed; some features (documentation links) disabled.
    • Basic roles defined, but permissions not thoroughly tested.
    • Default Voyager views are used.

  • Missing Implementation:

    • Comprehensive role/permission testing specific to Voyager functionalities.
    • Voyager view customization to address potential information disclosure.
    • Regular Voyager-specific configuration review schedule.

Mitigation Strategy: Strict BREAD Configuration and Data Handling (Voyager-Specific)

  • Description:

    1. BREAD Definition Review (Voyager): For each model managed by Voyager, meticulously review the BREAD configuration. This is often defined within the model itself or in a separate configuration file specifically for Voyager.
    2. Voyager Field Visibility: Use Voyager's BREAD settings to explicitly control which fields are visible in Voyager's "Browse" and "Read" views. Never expose sensitive fields through Voyager's interface.
    3. Voyager Editability Control: Use Voyager's BREAD settings to specify which fields are editable in Voyager's "Edit" and "Add" views. Exclude sensitive fields. Consider making fields read-only within Voyager even for administrators.
    4. Voyager-Specific Validation: Implement validation rules within Voyager's BREAD configuration. This adds a layer of validation specific to the Voyager interface, even if you have model-level validation.
    5. Voyager Relationship Management: Carefully configure how relationships are displayed and managed within Voyager. Ensure related data is not inadvertently exposed through Voyager's interface.
    6. Data Sanitization within Voyager Views: Before displaying any data within Voyager's views, ensure it's properly sanitized to prevent XSS. This is crucial even if you sanitize data elsewhere, as Voyager's views might have different handling.

  • Threats Mitigated:

    • Unintended Data Exposure (Voyager-Specific) (Severity: High): Prevents sensitive data display through Voyager's BREAD interfaces.
    • Data Tampering (Voyager-Specific) (Severity: High): Voyager-specific validation rules prevent malicious input within the Voyager interface.
    • Cross-Site Scripting (XSS) (Voyager-Specific) (Severity: High): Data sanitization within Voyager views prevents XSS.

  • Impact:

    • Unintended Data Exposure (Voyager-Specific): High impact; prevents data leaks within Voyager.
    • Data Tampering (Voyager-Specific): High impact; protects data integrity within Voyager.
    • Cross-Site Scripting (XSS) (Voyager-Specific): High impact; mitigates XSS within Voyager.

  • Currently Implemented:

    • Basic BREAD configurations exist.
    • Some fields hidden in Voyager's "Browse" view.
    • Basic Laravel validation, but not Voyager-specific.

  • Missing Implementation:

    • Comprehensive review of all BREAD configurations to exclude all sensitive fields from Voyager.
    • Implementation of Voyager-specific validation rules.
    • Thorough testing of relationship handling within Voyager.
    • Explicit data sanitization within Voyager's views.

Mitigation Strategy: Secure Media Manager Configuration (Voyager-Specific)

  • Description:

    1. Voyager File Type Restriction: In config/voyager.php, strictly define allowed file types for Voyager's media manager using both MIME types and extensions. Only allow the absolute minimum necessary.
    2. Voyager Storage Path: Configure the storage path for Voyager's uploaded files. Ideally, store files outside the web root. If within the web root, use .htaccess (Apache) or equivalent server configuration to prevent execution of uploaded files. This configuration is often found within Voyager's settings.
    3. Voyager File Size Limits: Set file size limits within Voyager's configuration.
    4. Voyager Filename Sanitization: Implement filename sanitization specifically for files uploaded through Voyager. Remove or replace dangerous characters. Consider using a UUID or hash as the filename.
    5. Disable Unused Features: If features like cropping, resizing are not used within Voyager's media manager, disable them in the configuration.
    6. Consider alternative: If possible, use external service and disable Voyager's media manager.

  • Threats Mitigated:

    • Arbitrary File Upload (Voyager-Specific) (Severity: High): Prevents malicious file uploads through Voyager's media manager.
    • Directory Traversal (Voyager-Specific) (Severity: High): Filename sanitization prevents access to files outside Voyager's upload directory.
    • Denial of Service (DoS) (Voyager-Specific) (Severity: Medium): File size limits prevent DoS through Voyager's media manager.
    • Cross-Site Scripting (XSS) (Voyager-Specific) (Severity: High): Preventing upload of HTML or JavaScript files through Voyager.
    • Remote Code Execution (RCE) (Voyager-Specific) (Severity: Critical): Preventing upload of executable files through Voyager.

  • Impact:

    • Arbitrary File Upload (Voyager-Specific): High impact; prevents critical breaches.
    • Directory Traversal (Voyager-Specific): High impact; protects sensitive files.
    • Denial of Service (DoS) (Voyager-Specific): Medium impact; improves stability.
    • Cross-Site Scripting (XSS) (Voyager-Specific): High impact; mitigates XSS.
    • Remote Code Execution (RCE) (Voyager-Specific): Critical impact; prevents compromise.

  • Currently Implemented:

    • Basic file type restrictions (images only).
    • Files stored within the web root (public/storage).

  • Missing Implementation:

    • Stricter file type restrictions (MIME types and extensions) within Voyager's config.
    • Moving storage outside the web root or using robust .htaccess rules, configured for Voyager.
    • Filename sanitization specific to Voyager's uploads.
    • Disabling unused features in Voyager's media manager.
    • Considering external service.

Mitigation Strategy: Enhanced Logging and Auditing (Voyager-Specific)

  • Description:

    1. Identify Critical Voyager Actions: Determine which Voyager-specific actions to log. This includes:
      • Voyager user logins and logouts.
      • Changes to Voyager roles and permissions.
      • Data creation/modification/deletion performed through Voyager's BREAD interfaces.
      • Actions within Voyager's media manager (file uploads, deletions).
      • Any custom actions added to Voyager.
    2. Implement Voyager-Specific Logging: Use Laravel's logging facilities, but focus on logging actions within Voyager. You can often use Voyager's event system (hooks) to trigger logging when specific Voyager actions occur. Log sufficient detail for forensic analysis (user, timestamp, affected data, parameters).
    3. Log Rotation: Configure log rotation for Voyager-specific logs.
    4. Regular Voyager Log Review: Establish a process for regularly reviewing logs specifically generated by Voyager for suspicious activity.

  • Threats Mitigated:

    • Insider Threats (Voyager-Specific) (Severity: Medium-High): Logs help detect malicious actions by authorized users within Voyager.
    • Compromised Accounts (Voyager-Specific) (Severity: High): Logs reveal unusual activity patterns within Voyager.
    • Security Incident Investigation (Voyager-Specific) (Severity: High): Logs are essential for investigating Voyager-related incidents.
    • Non-Repudiation (Voyager-Specific) (Severity: Medium): Logs provide an audit trail of actions within Voyager.

  • Impact:

    • Insider Threats (Voyager-Specific): Medium-high impact; improves detection.
    • Compromised Accounts (Voyager-Specific): High impact; enables early detection.
    • Security Incident Investigation (Voyager-Specific): High impact; provides crucial information.
    • Non-Repudiation (Voyager-Specific): Medium impact; strengthens accountability.

  • Currently Implemented:

    • Basic Laravel logging, but no Voyager-specific logging.

  • Missing Implementation:

    • Implementing custom logging for critical Voyager actions using Voyager's event system.
    • Establishing a regular review process for Voyager-specific logs.

Mitigation Strategy: Verify CSRF Protection (within Voyager)

  • Description:

    1. Confirm Laravel CSRF is Enabled: Ensure Laravel's CSRF protection is enabled (usually the default).
    2. Voyager Forms: @csrf Directive: Verify that all forms generated by Voyager (including BREAD forms) include the @csrf Blade directive. This is crucial for Voyager's built-in forms.
    3. Custom Forms within Voyager: If you create any custom forms within Voyager's views or controllers, ensure they also include the @csrf directive.
    4. Test: Submit forms with and without the token to verify that protection is working within the Voyager interface.

  • Threats Mitigated:

    • Cross-Site Request Forgery (CSRF) (Voyager-Specific) (Severity: High): Prevents attackers from tricking users into performing unintended actions within Voyager.

  • Impact:

    • Cross-Site Request Forgery (CSRF) (Voyager-Specific): High impact; mitigates CSRF within Voyager.

  • Currently Implemented:

    • Laravel's CSRF protection is enabled.
    • Most Voyager forms appear to include @csrf.

  • Missing Implementation:

    • Systematic verification that all forms within Voyager (including custom ones) have CSRF protection.
    • Testing to confirm CSRF protection works correctly within Voyager.
