(HR)

Attack Tree Path: Vulnerable Dependency (HR)

  • Description: An attacker exploits a known vulnerability in a third-party library or dependency used by Docuseal (e.g., a Node.js package, database driver, or other component).
  • Likelihood: Medium to High
  • Impact: Low to Very High (depends on the specific vulnerability)
  • Effort: Low to High (exploiting known vulnerabilities is often low effort)
  • Skill Level: Low to Very High (exploiting known vulnerabilities requires low skill)
  • Detection Difficulty: Low to Medium

Attack Tree Path: Misconfigured Storage Permissions (HR)

  • Description: An attacker gains unauthorized access to documents or data stored by Docuseal due to misconfigured permissions on cloud storage services (e.g., AWS S3, Azure Blob Storage).
  • Likelihood: Medium
  • Impact: High to Very High
  • Effort: Low
  • Skill Level: Low
  • Detection Difficulty: Low to Medium

Attack Tree Path: Weak Authentication

Attack Tree Path: [[Default Credentials (HR)]]

  • Description: An attacker gains administrative access by using default credentials that were not changed after installation.
  • Likelihood: Low (if best practices are followed)
  • Impact: Very High
  • Effort: Very Low
  • Skill Level: Very Low
  • Detection Difficulty: Low

Attack Tree Path: [[Brute-Force Login (HR)]]

  • Description: An attacker gains access to a user account by systematically trying different passwords.
  • Likelihood: Medium to High (if no account lockout or rate limiting)
  • Impact: High
  • Effort: Low to Medium
  • Skill Level: Low
  • Detection Difficulty: Low to Medium

Attack Tree Path: Document Template Manipulation

Attack Tree Path: [[Inject Malicious Code into Template (HR)]]

  • Description: An attacker injects malicious code (e.g., JavaScript) into a document template, which is then executed when the document is viewed or processed.
  • Likelihood: Medium to High (depends on input validation)
  • Impact: High to Very High
  • Effort: Low to Medium
  • Skill Level: Low to High
  • Detection Difficulty: Medium to High

Attack Tree Path: Submission Data Injection

Attack Tree Path: [[Inject XSS Payload into Submission Data (HR)]]

  • Description: An attacker injects a malicious XSS payload into form fields, which is then executed in the context of other users' browsers.
  • Likelihood: Medium to High (depends on output encoding)
  • Impact: Medium to High
  • Effort: Low
  • Skill Level: Low
  • Detection Difficulty: Medium

Attack Tree Path: [[Inject SQL into Data Fields (HR)]]

  • Description: An attacker injects SQL code into form fields to manipulate or extract data from the database.
  • Likelihood: Low to Medium (if parameterized queries are used)
  • Impact: Very High
  • Effort: Low to Medium
  • Skill Level: Low to High
  • Detection Difficulty: Low to Medium

Attack Tree Path: Signature Process Forgery/Bypass

Attack Tree Path: [[Forge Digital Signature (HR)]]

  • Description: An attacker forges a digital signature, allowing them to create fraudulent documents that appear to be legitimately signed.
  • Likelihood: Very Low to Low (If strong cryptography is used)
  • Impact: Very High
  • Effort: Very High
  • Skill Level: Very High
  • Detection Difficulty: High
