Mitigation Strategies Analysis for docusealco/docuseal

Mitigation Strategy: Implement Robust Document Hashing and Verification (Docuseal Integration)

  • Mitigation Strategy: Robust Document Hashing and Verification (Docuseal Integration)
  • Description:
    1. Utilize Docuseal's API or Hooks (if available): Explore Docuseal's API or available hooks to integrate document hashing into its workflow. If Docuseal provides events for document upload, signing, and finalization, use these to trigger hash generation.
    2. Customize Docuseal Workflow (if possible): If Docuseal allows workflow customization, integrate hash verification steps into the document workflow. For example, before displaying a document for signing, automatically verify its hash.
    3. Extend Docuseal Data Model (if possible): If Docuseal's data model is extensible, add fields to store document hashes at different stages (uploaded hash, signed hash, finalized hash).
    4. Develop Custom Verification UI/Functionality: If Docuseal doesn't provide built-in hash verification UI, develop custom UI elements or functions that allow users or administrators to manually trigger and view hash verification results.
    5. Integrate with External Hash Storage (if needed): If Docuseal's storage is not suitable for secure hash storage, integrate with an external secure storage service to store and retrieve document hashes.
    6. Log Hash Verification Events within Docuseal: Ensure that hash verification attempts and results are logged within Docuseal's logging system for auditing and troubleshooting.
  • Threats Mitigated:
    • Document Tampering (High Severity): Unauthorized modification of documents within the Docuseal workflow.
    • Integrity Violation (High Severity): Loss of confidence in the authenticity and reliability of documents processed by Docuseal.
    • Non-Repudiation Weakness (Medium Severity): Difficulty in proving document integrity within the Docuseal signing process if tampering occurs undetected.
  • Impact:
    • Document Tampering: Significantly Reduced within Docuseal. Hash verification makes tampering easily detectable within the platform.
    • Integrity Violation: Significantly Reduced for documents managed by Docuseal. Provides strong evidence of document integrity within the system.
    • Non-Repudiation Weakness: Partially Reduced within Docuseal signing workflows. Strengthens non-repudiation by ensuring document integrity during the signing process.
  • Currently Implemented: Likely not implemented as a user-facing feature or workflow integration within standard Docuseal. Core Docuseal might use internal hashing for its own data integrity, but not exposed for application-level verification.
  • Missing Implementation: Missing integration of hash generation and verification into Docuseal's document workflows, user interface, and data model. Custom development and potentially Docuseal API/hook utilization are required.
