Threat Model Analysis for lucasg/dependencies

Threat: Vulnerable Dependency Exploitation

Description: An attacker exploits a known security vulnerability in a third-party dependency used by the application. Exploitation can lead to Remote Code Execution (RCE) or Data Breach. Impact:

  • Critical: Remote Code Execution (RCE) allowing the attacker to gain full control of the server.
  • High: Data Breach, exposing sensitive application data or user information. Affected Component: Specific vulnerable dependency library or package. Risk Severity: Critical (can be critical if RCE is possible). Mitigation Strategies:
  • Regularly scan dependencies for vulnerabilities using automated tools.
  • Prioritize and apply security updates for vulnerable dependencies promptly.
  • Implement a dependency vulnerability management process.

Threat: Malicious Dependency Injection (Dependency Poisoning)

Description: An attacker injects malicious code into the application by compromising a dependency. This can lead to Remote Code Execution (RCE), Backdoor creation, or Data Exfiltration. Impact:

  • Critical: Remote Code Execution (RCE) allowing the attacker to gain full control of the server.
  • Critical: Backdoor creation, allowing persistent unauthorized access to the application and server.
  • High: Data Exfiltration, stealing sensitive application data or user information. Affected Component: The entire application codebase, build process, and dependency installation scripts. Risk Severity: Critical. Mitigation Strategies:
  • Use dependency pinning and lock files to ensure consistent dependency versions.
  • Verify package integrity using checksums or signatures.
  • Monitor dependency sources and security advisories related to package repositories.
  • Consider using private package repositories for internal dependencies and carefully vet external ones.

Threat: Dependency Confusion/Substitution Attack

Description: An attacker substitutes a legitimate private dependency with a malicious public one, potentially leading to Remote Code Execution (RCE) or Data Exfiltration. Impact:

  • Critical: Remote Code Execution (RCE) if the malicious package contains code that executes upon installation or usage.
  • High: Data Exfiltration, if the malicious package is designed to steal data. Affected Component: Dependency resolution process, package manager configuration. Risk Severity: High (can be critical if RCE is possible). Mitigation Strategies:
  • Use namespace prefixes or unique naming conventions for private packages.
  • Configure package managers to prioritize private repositories or explicitly define dependency sources.
  • Monitor dependency resolution logs for unexpected public package installations.

Threat: Supply Chain Compromise of Dependency Sources

Description: An attacker compromises a dependency source (package repository, mirror, CDN) and injects malicious code into legitimate packages, leading to widespread Remote Code Execution (RCE) and Data Breaches. Impact:

  • Critical: Widespread distribution of malicious code, potentially affecting numerous applications and systems.
  • Critical: Remote Code Execution (RCE) on systems that use the compromised packages.
  • High: Massive data breaches and system compromises across multiple organizations. Affected Component: Package repositories, mirrors, CDNs, and any system relying on packages from these sources. Risk Severity: Critical. Mitigation Strategies:
  • Use trusted and reputable package repositories and mirrors.
  • Implement integrity checks for downloaded packages using checksums or signatures.
  • Consider using dependency proxy caches or internal mirrors to control and inspect downloaded packages.

Threat: Outdated Transitive Dependencies

Description: The application uses direct dependencies that rely on outdated transitive dependencies with known vulnerabilities, potentially leading to Remote Code Execution (RCE). Impact:

  • Critical: Remote Code Execution (RCE) depending on the vulnerability in the transitive dependency.
  • High: Increased attack surface due to known vulnerabilities. Affected Component: Transitive dependencies, dependency management system. Risk Severity: High (can be critical if RCE is possible). Mitigation Strategies:
  • Regularly audit and update both direct and transitive dependencies.
  • Use dependency scanning tools that identify vulnerabilities in transitive dependencies.
  • Employ dependency management tools that provide insights into the dependency tree.
