Mitigation Strategies Analysis for docusealco/docuseal

Mitigation Strategy: Strict Access Control within Docuseal (RBAC)

Mitigation Strategy: Implement and enforce granular Role-Based Access Control (RBAC) within Docuseal's built-in features.

  • Description (Step-by-Step):

    1. Identify Roles: Define user roles specific to Docuseal usage (e.g., "Template Designer," "Document Sender," "Signer," "Approver," "Auditor").
    2. Define Permissions: For each role, meticulously define the allowed actions within Docuseal:
      • Creating/modifying/deleting templates.
      • Sending documents to specific recipients.
      • Accessing/viewing specific documents or folders.
      • Signing documents.
      • Approving documents.
      • Managing users and permissions (Admin role).
      • Accessing audit logs.
    3. Assign Users: Assign each user to the appropriate role(s) within Docuseal's user management interface.
    4. Regular Review: Regularly (e.g., quarterly) review user roles and permissions within Docuseal. Remove or adjust access as needed. Automate if possible.
    5. Test: Thoroughly test each role to ensure users can only perform their intended actions and cannot access unauthorized features or documents.

  • Threats Mitigated:

    • Unauthorized Document Access (High Severity): Prevents users from accessing documents they shouldn't.
    • Data Leakage (High Severity): Reduces the risk of sensitive document exposure.
    • Insider Threats (Medium to High Severity): Limits the damage a malicious insider can do.
    • Accidental Data Modification/Deletion (Medium Severity): Reduces accidental changes.

  • Impact:

    • All Threats: Risk significantly reduced. RBAC within Docuseal is a primary defense.

  • Currently Implemented:

    • Check Docuseal's settings for "Roles," "Permissions," "Access Control."
    • Examine the user management interface for role assignment options.
    • Review existing user accounts and their roles.

  • Missing Implementation:

    • If Docuseal lacks built-in RBAC, this is a critical gap. Consider feature requests or workarounds (if possible, but complex).
    • If RBAC is present but not granular enough, identify missing permissions/roles.
    • If user role reviews are not performed, establish a process.

Mitigation Strategy: Secure Docuseal Configuration (Storage & Settings)

Mitigation Strategy: Configure Docuseal's settings and storage options securely, focusing on data protection and access control.

  • Description (Step-by-Step):

    1. Storage Location: Understand exactly where Docuseal stores documents (database, filesystem, external service). Refer to Docuseal's documentation.
    2. Database Settings (if applicable):
      • Dedicated User: Ensure Docuseal uses a dedicated database user with minimal privileges (only on relevant tables). Never use the database root/admin account.
      • Strong Password: Set a strong, unique password for the Docuseal database user within Docuseal's configuration.
    3. Filesystem Settings (if applicable):
      • Restrictive Permissions: Configure the document storage directory within Docuseal to use the most restrictive permissions possible. Only the Docuseal application's user should have access.
    4. External Storage (if applicable):
      • Least Privilege: Configure Docuseal to use credentials with only the necessary permissions on the external storage service (e.g., read/write to a specific bucket).
    5. Review All Settings: Carefully review all of Docuseal's configuration settings (e.g., config.yml, .env, admin panel). Look for any settings related to security, data storage, access control, or authentication. Disable any unnecessary features.
    6. Disable Unused Features: If Docuseal has features you don't need (e.g., certain integrations, optional modules), disable them to reduce the attack surface.

  • Threats Mitigated:

    • Unauthorized Document Access (High Severity): Prevents direct access to stored documents.
    • Data Breach (High Severity): Reduces the impact of a compromise.
    • Data Loss (High Severity): Secure storage and backups (configured externally) are crucial.
    • SQL Injection (High Severity): Secure database configuration limits the impact.

  • Impact:

    • All Threats: Risk significantly reduced. This is a fundamental security layer.

  • Currently Implemented:

    • Examine Docuseal's configuration files for storage settings.
    • Check database user permissions (if applicable).
    • Inspect filesystem permissions (if applicable).
    • Review external storage credentials (if applicable).

  • Missing Implementation:

    • If Docuseal uses default or overly permissive credentials, this is a critical vulnerability.
    • If filesystem permissions are too broad, this is a critical vulnerability.
    • If external storage credentials have excessive permissions, this is a critical vulnerability.

Mitigation Strategy: Input Validation and Sanitization (Within Docuseal Templates)

Mitigation Strategy: Ensure Docuseal properly validates and sanitizes all user-provided data used within document templates and dynamic content.

  • Description (Step-by-Step):

    1. Identify Input Points: Identify all places within Docuseal's template creation and document generation process where user input is used (form fields, variables, etc.).
    2. Define Allowed Input: For each input field, define the expected data type and any constraints (length, allowed characters, format).
    3. Validate (Within Docuseal): If Docuseal provides mechanisms for input validation (e.g., field type settings, validation rules), use them to enforce the defined constraints.
    4. Sanitize (Within Docuseal): If Docuseal offers sanitization options (e.g., HTML escaping for text fields), use them appropriately.
    5. Template Engine Security: If Docuseal uses a templating engine, ensure it's configured securely and automatically escapes output to prevent XSS. Refer to the templating engine's documentation.
    6. Testing: Thoroughly test all input fields within Docuseal with valid and invalid data, including potential attack payloads.

  • Threats Mitigated:

    • Cross-Site Scripting (XSS) (Medium to High Severity): Prevents injecting malicious JavaScript into documents.
    • Template Injection (Medium to High Severity): Prevents manipulating the template itself.
    • Other Injection Attacks (Severity Varies): Mitigates potential injection vulnerabilities depending on how Docuseal uses input.

  • Impact:

    • XSS and Template Injection: Risk significantly reduced if Docuseal handles input securely.
    • Other Injection Attacks: Impact mitigated.

  • Currently Implemented:

    • Examine Docuseal's template creation interface and documentation for validation/sanitization options.
    • Review the templating engine used (if any) and its security settings.
    • Inspect generated documents for signs of proper escaping.

  • Missing Implementation:

    • If Docuseal lacks built-in validation/sanitization, this is a major concern. You might need to rely on external validation (before data reaches Docuseal) or consider modifying Docuseal's code (if open-source and you have the expertise).
    • If validation is weak or incomplete, this is a significant risk.
    • If HTML escaping is not used consistently, this is a significant XSS risk.

Mitigation Strategy: Audit Logging (Within Docuseal)

Mitigation Strategy: Enable and regularly review Docuseal's built-in audit logs.

  • Description (Step-by-Step):

    1. Enable Logging: Find Docuseal's logging settings (usually in the configuration or admin panel). Enable detailed logging of all relevant actions.
    2. Log Format: Ensure the logs include sufficient information: timestamp, user ID, IP address, action performed, document ID, success/failure status.
    3. Log Storage: Determine where Docuseal stores its logs (file, database). Ensure the logs are protected from unauthorized access and modification.
    4. Regular Review: Regularly (e.g., daily or weekly) review the Docuseal audit logs. Look for any suspicious activity, errors, or anomalies.
    5. Alerting (Ideally): If Docuseal supports it, configure alerts for specific events (e.g., failed login attempts, unauthorized access attempts, modifications to critical templates).

  • Threats Mitigated:

    • Unauthorized Access (High Severity): Helps detect and investigate unauthorized access attempts.
    • Insider Threats (Medium to High Severity): Provides a record of user actions for accountability.
    • Data Breaches (High Severity): Provides crucial information for incident response and forensics.
    • Compliance Violations (Severity Varies): Provides an audit trail for compliance purposes.

  • Impact:

    • Detection and Response: Significantly improves the ability to detect and respond to security incidents.
    • Accountability: Increases user accountability.
    • Forensics: Provides valuable data for forensic investigations.

  • Currently Implemented:

    • Check Docuseal's settings for "Logging," "Audit Logs," or similar options.
    • Examine the log files (if accessible) to see what information is recorded.

  • Missing Implementation:

    • If Docuseal lacks built-in audit logging, this is a significant deficiency. Consider requesting this feature or exploring workarounds (e.g., database triggers, if Docuseal uses a database).
    • If logging is enabled but not reviewed regularly, this reduces its effectiveness.
    • If logs lack sufficient detail, this hinders investigations.

Mitigation Strategy: Docuseal's Authentication and Session Management

Mitigation Strategy: Configure and utilize Docuseal's built-in authentication and session management features securely.

  • Description (Step-by-Step):

    1. Strong Passwords (Within Docuseal): If Docuseal manages its own user accounts, enforce strong password policies within Docuseal's settings (minimum length, complexity, expiration).
    2. Multi-Factor Authentication (MFA) (If Supported): If Docuseal offers MFA, enable and require it, especially for administrative accounts.
    3. Session Settings: Review Docuseal's session management settings (usually in the configuration or admin panel):
      • HTTPS Only: Ensure Docuseal is configured to only operate over HTTPS.
      • Secure Cookies: Ensure the Secure and HttpOnly flags are set for session cookies (Docuseal should handle this automatically, but verify).
      • Session Timeout: Configure a reasonable session timeout (e.g., 30 minutes of inactivity).
      • Session ID Generation: Docuseal should use a strong, cryptographically secure random number generator for session IDs.
    4. External Authentication (If Supported): If Docuseal supports integration with external identity providers (IdPs) via SAML or OpenID Connect, configure this integration securely, following best practices for the chosen protocol.

  • Threats Mitigated:

    • Unauthorized Access (High Severity): Strong authentication prevents unauthorized logins.
    • Session Hijacking (High Severity): Secure session management prevents attackers from stealing user sessions.
    • Brute-Force Attacks (Medium Severity): Strong passwords and MFA mitigate brute-force attacks.
    • Credential Stuffing (Medium Severity): Strong passwords and MFA mitigate credential stuffing.

  • Impact:

    • All Threats: Risk significantly reduced with strong authentication and secure session management.

  • Currently Implemented:

    • Check Docuseal's settings for "Authentication," "Security," "Users," "Sessions."
    • Examine the user management interface for password policy options.
    • Check for MFA settings.
    • Inspect browser cookies to verify Secure and HttpOnly flags.

  • Missing Implementation:

    • If Docuseal lacks strong password enforcement, this is a significant vulnerability.
    • If MFA is not supported or not used, this increases the risk of unauthorized access.
    • If session cookies are not secure, this is a critical vulnerability.
    • If session timeouts are too long, this increases the risk of session hijacking.
