Threat Model Analysis for mobile-dev-inc/maestro

Threat: Injection of Malicious Commands into Maestro Scripts

Description: An attacker injects malicious commands into Maestro YAML scripts. This could be achieved by compromising script repositories or manipulating scripts during development. When executed by Maestro, these commands can execute arbitrary code on the test device/emulator, exfiltrate data, or manipulate the application under test in harmful ways.

  • Impact: Code execution on test devices/emulators, significant data breaches from test environments, critical manipulation of application behavior leading to security vulnerabilities, potential compromise of Maestro Cloud account if scripts are stored there.
  • Maestro Component Affected: Maestro Script Engine, Maestro CLI, Maestro Cloud (if scripts are stored there).
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Implement strict access control and permissions for Maestro script repositories.
    • Mandatory and thorough code reviews for all Maestro scripts before use.
    • Utilize parameterized commands within scripts to prevent direct command construction from external inputs.
    • Regularly audit Maestro scripts for potential injection vulnerabilities using static analysis tools.

Threat: Exposure of Sensitive Information in Maestro Scripts

  • Description: Developers inadvertently hardcode sensitive information like API keys, credentials, or internal application secrets directly into Maestro scripts. If these scripts are not properly secured, attackers gaining unauthorized access (e.g., through repository breaches, accidental sharing) can extract this sensitive data.
  • Impact: Unauthorized access to critical APIs and backend services, compromise of application accounts and user data, severe exposure of sensitive application data and internal secrets, potential for widespread system compromise and further attacks using exposed credentials.
  • Maestro Component Affected: Maestro Scripts, Maestro Script Storage (repositories, local file system, Maestro Cloud).
  • Risk Severity: High
  • Mitigation Strategies:
    • Absolutely avoid hardcoding sensitive information directly in Maestro scripts.
    • Mandatory use of environment variables or secure vault solutions for managing sensitive configuration data.
    • Implement robust access control on Maestro script repositories and storage locations, restricting access to authorized personnel only.
    • Regularly scan Maestro scripts for secrets using automated secret scanning tools integrated into CI/CD pipelines.
    • Provide comprehensive security training to developers on secure coding practices for Maestro scripts and sensitive data handling.

Threat: Vulnerabilities in Maestro CLI Software

  • Description: Security vulnerabilities within the Maestro CLI software itself could be exploited by attackers. Successful exploitation could allow arbitrary code execution on the machine running the CLI, potentially leading to system compromise, control over the device/emulator being tested, and further attacks.
  • Impact: Code execution on developer machines or test infrastructure, privilege escalation, denial of service affecting testing capabilities, potential compromise of devices/emulators and the application under test if connected to live environments, significant disruption to development and testing workflows.
  • Maestro Component Affected: Maestro CLI Software.
  • Risk Severity: High
  • Mitigation Strategies:
    • Maintain Maestro CLI software at the latest version, ensuring timely application of security patches.
    • Actively subscribe to security advisories and release notes from the Maestro project to stay informed about potential vulnerabilities.
    • Download Maestro CLI exclusively from official and trusted sources to avoid tampered or malicious versions.
    • Implement network segmentation to limit the potential blast radius of a compromised CLI instance, isolating test environments from production networks.

Threat: Compromised Maestro Cloud Account

  • Description: If using Maestro Cloud, a compromised Maestro Cloud account (due to weak credentials, phishing, or account takeover) grants an attacker access to stored scripts, test results, device configurations, and the ability to execute tests on connected devices/emulators. This can lead to unauthorized access and manipulation of testing processes and data.
  • Impact: Data breaches from Maestro Cloud exposing sensitive test data and application information, unauthorized access to and manipulation of test environments, manipulation of test results leading to false positives or negatives, potential for denial of service affecting testing infrastructure, unauthorized execution of tests potentially consuming resources or causing unintended actions.
  • Maestro Component Affected: Maestro Cloud Account, Maestro Cloud Platform.
  • Risk Severity: High
  • Mitigation Strategies:
    • Enforce strong, unique password policies for all Maestro Cloud accounts, mandating complexity and regular password rotation.
    • Strictly enforce Multi-Factor Authentication (MFA) for all Maestro Cloud accounts to add an extra layer of security against credential compromise.
    • Implement granular Role-Based Access Control (RBAC) within Maestro Cloud to restrict user access to only necessary resources and functionalities based on their roles and responsibilities.
    • Regularly review and audit Maestro Cloud account access and permissions to identify and remediate any unauthorized or excessive access.
    • Implement robust monitoring and logging of Maestro Cloud account activity to detect and respond to suspicious login attempts or actions.

Threat: Data Breaches in Maestro Cloud Infrastructure

  • Description: As with any cloud service, there is an inherent risk of data breaches within the Maestro Cloud infrastructure itself. A successful breach could expose all data stored within Maestro Cloud, including scripts, test results, and potentially sensitive application data, to unauthorized actors.
  • Impact: Large-scale data breaches affecting all users of Maestro Cloud, widespread exposure of sensitive application data and test information, significant loss of confidentiality and integrity of test data, severe reputational damage to both Maestro Cloud and its users, potential legal and compliance violations due to data breaches.
  • Maestro Component Affected: Maestro Cloud Infrastructure, Maestro Cloud Data Storage.
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Thoroughly evaluate Maestro Cloud's security posture and compliance certifications (e.g., SOC 2, ISO 27001) to assess their security controls and practices.
    • Gain a deep understanding of Maestro Cloud's data encryption practices, ensuring robust encryption for data at rest and in transit to protect data confidentiality.
    • Carefully review Maestro Cloud's incident response plan and data breach notification procedures to understand their preparedness and processes in case of a security incident.
    • Ensure Maestro Cloud implements and maintains robust security measures across its infrastructure, including vulnerability management, intrusion detection and prevention systems, and regular security audits and penetration testing.
    • Implement data minimization and retention policies for data stored in Maestro Cloud, reducing the amount of sensitive data stored and limiting the retention period to minimize the impact of a potential breach.

Threat: Insecure API Access to Maestro Cloud

  • Description: If Maestro Cloud provides APIs for programmatic access, vulnerabilities in API security, such as weak authentication, missing authorization checks, or API injection flaws, could be exploited. Attackers could leverage these vulnerabilities to gain unauthorized access to Maestro Cloud resources, manipulate test executions, or exfiltrate sensitive data via insecure APIs.
  • Impact: Unauthorized access to sensitive Maestro Cloud data and configurations, manipulation of test configurations and execution workflows, potential for denial of service attacks targeting the API, data breaches through API vulnerabilities, potential for account takeover by exploiting API weaknesses.
  • Maestro Component Affected: Maestro Cloud APIs, Maestro Cloud API Gateway.
