Attack Surface Analysis for geb/geb

Attack Surface: Insecure WebDriver Binaries

  • Description: Using compromised, outdated, or unverified WebDriver binaries (like ChromeDriver, GeckoDriver) that Geb relies on.
  • Geb Contribution: Geb directly utilizes WebDriver binaries to control browsers. Insecure binaries compromise Geb's operation and the system.
  • Example: Downloading ChromeDriver from an unofficial source hosting a malware-infected version. Geb using this binary can lead to malware execution on the system running Geb.
  • Impact: Malware infection, system compromise, data breach, loss of confidentiality and integrity.
  • Risk Severity: High
  • Mitigation Strategies:
    • Developers/Users:
      • Download WebDriver binaries only from official and trusted sources (e.g., ChromeDriver from Google Chrome for Developers, GeckoDriver from Mozilla).
      • Implement checksum verification to ensure binary integrity against official checksums.
      • Keep WebDriver binaries updated to the latest stable and secure versions.

Attack Surface: WebDriver Server Exposure

  • Description: Exposing the WebDriver server (e.g., Selenium Grid hub or standalone server) to unauthorized access due to misconfiguration, when Geb is configured to use remote WebDriver.
  • Geb Contribution: Geb's ability to connect to remote WebDriver servers introduces a network service that, if insecure, becomes an attack vector.
  • Example: Running a Selenium Grid hub on a public network without authentication. Attackers can access the hub via Geb, control browser sessions, and potentially access internal systems if the hub is within a private network.
  • Impact: Unauthorized control of browser sessions, potential access to internal applications and data, denial of service against the WebDriver server.
  • Risk Severity: High
  • Mitigation Strategies:
    • Developers/Users:
      • Securely configure WebDriver servers with strong authentication and authorization.
      • Implement network segmentation and firewalls to restrict access to WebDriver servers.
      • Use secure communication protocols (HTTPS) for WebDriver server communication.

Attack Surface: Unintended Code Execution via Geb Scripts

  • Description: Exploiting vulnerabilities to inject and execute malicious code within Geb scripts, leveraging Groovy's dynamic nature.
  • Geb Contribution: Geb scripts are written in Groovy. If Geb scripts are dynamically generated based on untrusted input, code injection is possible.
  • Example: A Geb script reads configuration from a user-controlled file. An attacker modifies this file to inject malicious Groovy code into a Geb script, leading to arbitrary code execution when Geb runs the script.
  • Impact: Arbitrary code execution on the system running Geb, system compromise, data breach, denial of service.
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Developers:
      • Avoid dynamic generation of Geb scripts based on untrusted or external input.
      • If dynamic script generation is necessary, implement robust input validation and sanitization.
      • Follow secure coding practices in Groovy within Geb scripts.

Attack Surface: Vulnerabilities in Geb Extensions or Plugins

  • Description: Exploiting security vulnerabilities present in Geb extensions or plugins (either custom-built or third-party).
  • Geb Contribution: Geb's extensibility through plugins means vulnerabilities in these plugins directly impact Geb's security.
  • Example: Using a third-party Geb plugin with a code execution vulnerability. When Geb loads this plugin, the vulnerability can be exploited.
  • Impact: Code execution, security bypass, application manipulation, potential system compromise.
  • Risk Severity: High
  • Mitigation Strategies:
    • Developers:
      • Thoroughly vet and audit Geb extensions and plugins for security vulnerabilities before use.
      • Prefer well-established and actively maintained extensions from trusted sources.
      • Keep Geb extensions and plugins updated to patch known vulnerabilities.

Attack Surface: Deserialization Vulnerabilities (if applicable to Geb context)

  • Description: Exploiting deserialization vulnerabilities if Geb or its extensions use deserialization of data without proper security measures.
  • Geb Contribution: While not core, Geb or extensions could use deserialization for configuration or data handling, introducing deserialization risks.
  • Example: A Geb extension deserializes data from a configuration file. An attacker crafts a malicious serialized object in this file. Geb deserializing it leads to code execution.
  • Impact: Code execution, system compromise, data breach.
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Developers:
      • Avoid deserialization of untrusted data if possible.
      • If deserialization is necessary, use secure deserialization methods and libraries.
      • Implement robust input validation before deserialization.

Attack Surface: Vulnerabilities in Geb Dependencies

  • Description: Exploiting known vulnerabilities in the libraries and dependencies that Geb relies upon (e.g., Selenium WebDriver, Groovy, etc.).
  • Geb Contribution: Geb depends on libraries. Vulnerabilities in these dependencies indirectly become part of Geb's attack surface.
  • Example: Geb uses an outdated Selenium WebDriver version with a known vulnerability. Attackers could exploit this via interaction with the WebDriver instance Geb controls.
  • Impact: Exploitation of dependency vulnerabilities, potential code execution, system compromise, data breach.
  • Risk Severity: High
  • Mitigation Strategies:
    • Developers:
      • Regularly scan Geb and its dependencies for known vulnerabilities using dependency scanning tools.
      • Keep Geb and its dependencies updated to the latest secure versions.
      • Use dependency management tools to track and manage dependencies effectively.
