Attack Tree Path: 1.1.1.1 Lack of SSL/TLS Encryption for Broker-Client Communication

  • Attack Vector: Attacker sniffs network traffic between RocketMQ brokers and clients because communication is not encrypted using SSL/TLS.
  • Likelihood: Medium
  • Impact: High (Confidentiality breach, credential theft if credentials are transmitted in messages)
  • Effort: Low (Passive network sniffing using readily available tools)
  • Skill Level: Low (Basic network sniffing skills)
  • Detection Difficulty: Low (Network monitoring can detect unencrypted traffic on RocketMQ ports)
  • Actionable Insight: Enforce SSL/TLS encryption for all communication between RocketMQ brokers and clients. Configure both brokers and clients to use SSL/TLS.

Attack Tree Path: 1.1.2.1 Intercept and Modify Messages

  • Attack Vector: Attacker performs a Man-in-the-Middle (MITM) attack on unencrypted RocketMQ communication to intercept and modify messages in transit.
  • Likelihood: Medium (If SSL/TLS is not enabled, feasible on local networks, harder across the internet but still possible with compromised network segments)
  • Impact: High (Integrity compromise of messages, manipulation of application logic by altering message content)
  • Effort: Medium (Requires setting up MITM attack infrastructure, like ARP spoofing, and tools to intercept and modify network traffic)
  • Skill Level: Medium (Network manipulation and MITM attack techniques)
  • Detection Difficulty: Medium (Requires network anomaly detection systems to identify unusual traffic patterns and potential MITM activity)
  • Actionable Insight: Enforce SSL/TLS encryption to prevent MITM attacks. Consider mutual TLS (mTLS) for stronger authentication and to further mitigate impersonation risks.

Attack Tree Path: 1.2.1.1 Default Broker Port (9876, 10911, 10909, etc.) Exposed to Internet

  • Attack Vector: Attacker directly connects to publicly exposed RocketMQ broker ports from the internet.
  • Likelihood: Low (Organizations generally avoid direct internet exposure, but misconfigurations or oversight can occur)
  • Impact: Critical (Direct access to the broker, potential for full compromise of the RocketMQ system and connected applications)
  • Effort: Low (Simple port scanning and network connectivity checks from the internet)
  • Skill Level: Low (Basic network skills)
  • Detection Difficulty: Low (External port scans easily detect open ports, and network intrusion detection systems can flag unauthorized connections)
  • Actionable Insight: Restrict access to RocketMQ broker ports to only authorized networks and IP addresses. Use firewalls to block all public internet access to these ports.

Attack Tree Path: 1.2.3.1 Allowing Unnecessary Inbound Traffic to RocketMQ Ports

  • Attack Vector: Firewall misconfiguration allows unnecessary inbound traffic to RocketMQ ports from unauthorized networks or the internet.
  • Likelihood: Medium (Firewall rules can be complex, and misconfigurations are common, especially during rapid deployments or changes)
  • Impact: Medium (Depending on the extent of misconfiguration, could lead to unauthorized access to RocketMQ services from unintended sources)
  • Effort: Low (Exploiting existing firewall misconfigurations is easy once discovered)
  • Skill Level: Low (Basic network knowledge to identify open ports and test connectivity)
  • Detection Difficulty: Medium (Regular firewall rule reviews and network traffic monitoring can help detect and rectify misconfigurations)
  • Actionable Insight: Regularly review and audit firewall rules to ensure only necessary ports are open and access is strictly limited to authorized sources. Implement a "deny by default" firewall policy.

Attack Tree Path: 2.1.1.1 Using Default RocketMQ Credentials (if any exist and are not changed)

  • Attack Vector: Attacker attempts to log in to RocketMQ components (e.g., management console, broker if authentication is enabled with default accounts) using default usernames and passwords.
  • Likelihood: Low (Security best practices strongly recommend changing default credentials, but this is sometimes overlooked, especially in development or less critical environments)
  • Impact: Critical (Full administrative access to RocketMQ if default credentials are used for administrative accounts, potentially leading to complete system compromise)
  • Effort: Low (Trying default usernames and passwords, often readily available online)
  • Skill Level: Low (Script kiddie level attacks)
  • Detection Difficulty: Medium (Failed login attempts can be logged and monitored, but successful login using default credentials might be initially missed if not specifically monitored for)
  • Actionable Insight: Immediately change all default credentials for RocketMQ components and any related management tools. Implement strong password policies and regular password rotation.

Attack Tree Path: 2.1.3.1 RocketMQ Deployed without Authentication Enabled (if optional)

  • Attack Vector: RocketMQ is deployed without authentication mechanisms enabled, allowing anyone with network access to interact with the broker and nameserver without any credentials.
  • Likelihood: Low (Security-conscious deployments should enable authentication, but development or test environments might skip this step for convenience, and this configuration could mistakenly propagate to production)
  • Impact: Critical (Completely open access to RocketMQ services, allowing unauthorized message production, consumption, and administrative actions if management interfaces are also exposed)
  • Effort: Low (Direct access to RocketMQ services without needing any credentials)
  • Skill Level: Low (Basic network connectivity)
  • Detection Difficulty: Low (Easy to detect open access points by attempting to connect without credentials)
  • Actionable Insight: Enable and enforce authentication for all RocketMQ components. Utilize RocketMQ's built-in ACL feature or integrate with existing enterprise authentication systems.

Attack Tree Path: 2.2.1.1 Overly Permissive ACLs Granting Unnecessary Privileges

  • Attack Vector: RocketMQ Access Control Lists (ACLs) are configured too permissively, granting users or applications more privileges than necessary, allowing attackers to exploit these excessive permissions if they gain access.
  • Likelihood: Medium (ACL configuration can be complex, and mistakes in permission assignments are common, especially as applications evolve and new features are added)
  • Impact: Medium (Unauthorized actions within RocketMQ, such as publishing to or consuming from topics they shouldn't, potentially leading to data manipulation or information disclosure)
  • Effort: Low (Exploiting existing overly permissive permissions is easy once an attacker has any level of access to RocketMQ)
  • Skill Level: Low (Basic understanding of RocketMQ ACLs and how to interact with the broker)
  • Detection Difficulty: Medium (Regular ACL reviews and activity monitoring can help detect anomalies and identify overly broad permissions)
  • Actionable Insight: Implement granular and least-privilege ACLs. Define roles and permissions based on the principle of least privilege, ensuring users and applications only have the necessary permissions. Regularly review and update ACLs as needed.

Attack Tree Path: 4.1.1.1 Identify and Exploit Known CVEs in Running RocketMQ Version

  • Attack Vector: Attacker identifies known Common Vulnerabilities and Exposures (CVEs) in the running version of RocketMQ and exploits these vulnerabilities to compromise the system.
  • Likelihood: Medium (Organizations may lag in patching, especially for systems perceived as less critical or due to complex update processes)
  • Impact: Critical (Depending on the specific CVE, exploitation can lead to Remote Code Execution (RCE), privilege escalation, Denial of Service (DoS), or information disclosure, potentially resulting in full system compromise)
  • Effort: Medium (Exploits for known CVEs are often publicly available or easily developed, requiring some adaptation to the target environment)
  • Skill Level: Medium (Using existing exploits requires some technical skills, but detailed exploit instructions are often available)
  • Detection Difficulty: Medium (Vulnerability scanning tools can identify known CVEs, and Intrusion Detection Systems (IDS) can detect exploitation attempts if signatures are available)
  • Actionable Insight: Implement a robust patch management process. Regularly patch and update RocketMQ to the latest stable version to address known vulnerabilities. Subscribe to security advisories and CVE databases related to RocketMQ.

Attack Tree Path: 4.2.1.1 Exploiting Weak Default Settings in RocketMQ Configuration Files

  • Attack Vector: Attacker exploits weak or insecure default settings present in RocketMQ configuration files that have not been hardened by administrators.
  • Likelihood: Low (Organizations should customize configurations for production environments, but default settings can sometimes be weak and overlooked)
  • Impact: Medium (Depending on the specific default settings, this could lead to a weaker security posture, information disclosure, or increased attack surface)
  • Effort: Low (Reviewing default configurations and identifying security weaknesses is relatively straightforward)
  • Skill Level: Low (Basic security configuration knowledge and understanding of RocketMQ configuration parameters)
  • Detection Difficulty: Low (Configuration reviews and security audits can easily identify deviations from security best practices and the use of default settings)
  • Actionable Insight: Review and harden RocketMQ configuration based on security best practices and vendor recommendations. Avoid using default configurations in production environments. Implement configuration management tools to enforce secure configurations consistently.

Attack Tree Path: 4.2.2.1 Incorrectly Configured ACLs, Authentication, or Network Settings

  • Attack Vector: RocketMQ is misconfigured in terms of ACLs, authentication mechanisms, or network settings, leading to security weaknesses that attackers can exploit.
  • Likelihood: Medium (Complex systems are prone to misconfiguration, and human error during setup or changes can easily introduce security vulnerabilities)
  • Impact: High (Misconfigurations can lead to unauthorized access, data breaches, service disruption, or other significant security incidents)
  • Effort: Low (Exploiting existing misconfigurations is often easy once identified, requiring minimal effort)
  • Skill Level: Low (Basic understanding of RocketMQ configuration and common security misconfigurations)
  • Detection Difficulty: Medium (Configuration reviews, security audits, and anomaly detection systems can help identify misconfigurations, but proactive and regular checks are essential)
  • Actionable Insight: Thoroughly review and test RocketMQ configuration for security weaknesses. Use configuration management tools to ensure consistent and secure configurations across all RocketMQ components. Implement automated configuration checks and security audits.

Attack Tree Path: 4.3.1.1 Exploiting Vulnerabilities in RocketMQ's Dependencies (e.g., Netty, etc.)

  • Attack Vector: Attacker exploits known vulnerabilities in RocketMQ's dependencies, such as Netty or other libraries it relies upon.
  • Likelihood: Medium (Dependencies can have vulnerabilities, and organizations may not always track and patch them as diligently as the main application)
  • Impact: Critical (Depending on the severity and nature of the dependency vulnerability, exploitation can lead to Remote Code Execution (RCE), Denial of Service (DoS), or other critical impacts, potentially compromising the entire RocketMQ system)
  • Effort: Medium (Exploits for dependency CVEs might be publicly available or require some adaptation, similar to exploiting RocketMQ CVEs)
  • Skill Level: Medium (Using existing exploits and understanding dependency relationships requires some technical skills)
  • Detection Difficulty: Medium (Vulnerability scanning tools and Software Composition Analysis (SCA) tools can identify vulnerable dependencies, but proactive dependency management is crucial)
  • Actionable Insight: Implement a robust dependency management process. Regularly scan RocketMQ dependencies for vulnerabilities using SCA tools. Update dependencies to patched versions promptly.

Attack Tree Path: 4.3.2.1 RocketMQ Running with Outdated and Vulnerable Dependencies

  • Attack Vector: RocketMQ is running with outdated versions of its dependencies, which are known to contain security vulnerabilities.
  • Likelihood: Medium (Organizations may lag in updating dependencies due to compatibility concerns, testing requirements, or simply oversight)
  • Impact: Medium (Running with outdated dependencies increases the attack surface and exposes the system to known vulnerabilities that could be easily exploited)
  • Effort: Low (Identifying outdated dependencies is straightforward using dependency scanning tools)
  • Skill Level: Low (Basic dependency management knowledge)
  • Detection Difficulty: Low (Dependency scanning tools easily detect outdated versions and can generate reports highlighting vulnerable components)
  • Actionable Insight: Keep RocketMQ and its dependencies up-to-date. Implement a dependency management process that includes regular updates and vulnerability scanning.

Attack Tree Path: 5.1.1.1 Management Interface (e.g., HTTP Dashboard, JMX) Exposed to Internet

  • Attack Vector: RocketMQ's management interface (e.g., HTTP dashboard, JMX port) is mistakenly or intentionally exposed to the public internet.
  • Likelihood: Low (Should be avoided in production environments, but misconfigurations or lack of awareness can lead to accidental exposure)
  • Impact: Critical (Administrative access to RocketMQ via the management interface, potentially allowing full control over the system, message queues, and configurations)
  • Effort: Low (Simple port scanning and network connectivity checks from the internet)
  • Skill Level: Low (Basic network skills)
  • Detection Difficulty: Low (External port scans and web application firewalls can easily detect publicly accessible management interfaces)
  • Actionable Insight: Never expose the RocketMQ management interface directly to the internet. Restrict access to authorized internal networks only. Use VPNs or bastion hosts for remote administrative access if needed.

Attack Tree Path: 5.1.2.1 Default Credentials or Weak Passwords for Management Interface

  • Attack Vector: Attacker attempts to log in to the RocketMQ management interface using default credentials or weak passwords.
  • Likelihood: Low (Best practices dictate using strong passwords, but weak or default passwords are still common, especially if initial setup is rushed or security is not prioritized)
  • Impact: Critical (Administrative access to RocketMQ via the management interface, allowing full control over the system, message queues, and configurations)
  • Effort: Low (Brute-force attacks or trying default credentials, often readily available online)
  • Skill Level: Low (Script kiddie level attacks)
  • Detection Difficulty: Medium (Failed login attempt monitoring and account lockout policies can help, but successful login with weak credentials might be missed if not specifically monitored for)
  • Actionable Insight: Enforce strong authentication for the management interface. Change default credentials immediately and implement strong password policies, including complexity requirements and regular password rotation. Consider implementing multi-factor authentication (MFA) for enhanced security.
