Attack Tree Path: 1.1.1.1. Exploit SQL Injection in Admin Panel Login [HR] [CN]

  • Attack Vector: Attacker attempts to inject malicious SQL code into the login form fields of the Chameleon admin panel. If successful, the attacker can bypass authentication and gain direct access to the database.
  • Likelihood: Medium
  • Impact: Critical - Full database access, potential system compromise.
  • Effort: Low - Automated tools are readily available, and SQL injection is a common attack vector.
  • Skill Level: Medium - Basic SQL injection knowledge is sufficient, and tools simplify the process.
  • Detection Difficulty: Medium - Web Application Firewalls (WAFs) and Intrusion Detection Systems (IDSs) can detect some SQL injection attempts, but bypasses exist.

Attack Tree Path: 1.1.3.1. Stored XSS in Feature Flag Names/Descriptions [HR]

  • Attack Vector: Attacker injects malicious JavaScript code into fields like feature flag names or descriptions within the Chameleon admin panel. When an administrator views these fields, the stored XSS payload executes in their browser, potentially leading to session hijacking or further malicious actions within the admin panel.
  • Likelihood: Medium
  • Impact: Medium - Admin account compromise, potential application manipulation through the admin panel.
  • Effort: Low - Easy to test and exploit, XSS is a common vulnerability.
  • Skill Level: Low - Basic XSS knowledge is required.
  • Detection Difficulty: Easy - Input validation and output encoding can prevent stored XSS. Vulnerability scanners can also detect these issues.

Attack Tree Path: 1.2.1.1. Access Admin Panel with Default Credentials [HR] [CN]

  • Attack Vector: Attacker attempts to log in to the Chameleon admin panel using default usernames and passwords that might be shipped with the software or easily guessable. If default credentials are not changed after installation, the attacker gains immediate administrative access.
  • Likelihood: Low - Developers should change defaults, but it's sometimes overlooked, especially in quick setups or testing environments.
  • Impact: Critical - Full admin access to Chameleon.
  • Effort: Very Low - Simply trying default credentials.
  • Skill Level: Very Low - No specific skills required.
  • Detection Difficulty: Very Easy - Should be prevented by secure setup procedures and configuration management.

Attack Tree Path: 1.2.2.1. Brute-force Admin Panel Credentials [HR]

  • Attack Vector: Attacker uses automated tools to try a large number of username and password combinations to guess valid admin panel credentials. If the password policy is weak (e.g., short passwords, no complexity requirements), brute-force attacks become more feasible.
  • Likelihood: Medium - If the password policy is weak, brute-force attacks become a viable option.
  • Impact: Critical - Full admin access to Chameleon.
  • Effort: Medium - Requires password cracking tools and time, but can be automated.
  • Skill Level: Low to Medium - Basic knowledge of brute-force tools is needed.
  • Detection Difficulty: Medium - Account lockout mechanisms and rate limiting can detect and mitigate brute-force attempts, but stealthy attacks are still possible.

Attack Tree Path: 1.2.3.1. Exploit Authentication Bypass Vulnerability in Admin Panel [HR] [CN]

  • Attack Vector: Attacker discovers and exploits a vulnerability in the Chameleon admin panel's authentication mechanism that allows them to bypass the login process without valid credentials. This could be due to logical flaws in the code, misconfigurations, or vulnerabilities in authentication libraries.
  • Likelihood: Low - Less common if standard authentication libraries are used securely, but possible in custom-built authentication code.
  • Impact: Critical - Full admin access to Chameleon.
  • Effort: Medium to High - Requires vulnerability research, code analysis, and potentially exploit development.
  • Skill Level: High - Requires understanding of authentication protocols and exploit development skills.
  • Detection Difficulty: Hard - Requires thorough code review and penetration testing to identify such vulnerabilities.

Attack Tree Path: 1.2.4.1. Session Hijacking (e.g., Session Fixation, Cookie Theft) [HR]

  • Attack Vector: Attacker attempts to steal or manipulate a valid admin session to gain unauthorized access. This can be achieved through various techniques like session fixation (forcing a known session ID), cookie theft (e.g., via XSS or network interception), or session prediction if session IDs are weak.
  • Likelihood: Low to Medium - Depends on the session management implementation and security measures in place.
  • Impact: Medium to High - Admin session takeover, allowing unauthorized actions within the admin panel.
  • Effort: Low to Medium - Tools are available for session hijacking, and techniques range from network interception to social engineering.
  • Skill Level: Medium - Requires networking knowledge and understanding of session management concepts.
  • Detection Difficulty: Medium - Session monitoring and anomaly detection can help identify session hijacking attempts.

Attack Tree Path: 1.2.5.1. Elevate Privileges to Admin Role [HR] [CN]

  • Attack Vector: Attacker exploits an authorization vulnerability to escalate their privileges from a regular user (or unauthenticated state) to an administrator role within the Chameleon admin panel. This could be due to flaws in role-based access control (RBAC) implementation or missing authorization checks.
  • Likelihood: Low - Authorization flaws are generally less common than authentication flaws, but still possible.
  • Impact: Critical - Full admin access to Chameleon.
  • Effort: Medium to High - Requires code analysis and understanding of the authorization logic to identify and exploit such flaws.
  • Skill Level: High - Requires understanding of authorization concepts and code analysis skills.
  • Detection Difficulty: Hard - Requires thorough code review and penetration testing to identify authorization bypass vulnerabilities.

Attack Tree Path: 1.3.1. Exploit Insecure Deserialization in API or Admin Panel [CN]

  • Attack Vector: If Chameleon uses deserialization of untrusted data (e.g., in API requests or admin panel functionalities), an attacker can craft malicious serialized data that, when deserialized by the application, leads to remote code execution on the server. While Go is generally less prone to this, it's still possible if external libraries with such vulnerabilities are used.
  • Likelihood: Very Low - Go is less susceptible to insecure deserialization compared to some other languages, but depends on specific libraries and code.
  • Impact: Critical - Remote code execution, full system compromise.
  • Effort: High - Requires deep understanding of serialization mechanisms, vulnerability research, and exploit development.
  • Skill Level: Expert - Requires expertise in serialization vulnerabilities and exploit development.
  • Detection Difficulty: Very Hard - Requires in-depth code review and specialized security tools to detect and prevent.

Attack Tree Path: 1.5.1. Perform Unauthorized Actions via CSRF in Admin Panel [HR]

  • Attack Vector: If the Chameleon admin panel lacks Cross-Site Request Forgery (CSRF) protection, an attacker can trick an authenticated administrator into unknowingly performing actions they didn't intend. This is typically done by embedding malicious requests in links or iframes on attacker-controlled websites or emails.
  • Likelihood: Medium - Common if CSRF protection is not implemented, especially in older or less security-focused applications.
  • Impact: Medium - Unauthorized admin actions, potentially leading to data manipulation, configuration changes, or other malicious activities within Chameleon.
  • Effort: Low - Easy to test and exploit, CSRF is a well-known attack vector.
  • Skill Level: Low - Basic web security knowledge is sufficient.
  • Detection Difficulty: Easy - CSRF tokens and SameSite cookies are effective prevention mechanisms. Vulnerability scanners can also detect missing CSRF protection.

Attack Tree Path: 1.7.1. Resource Exhaustion via API Abuse [HR]

  • Attack Vector: If the Chameleon API lacks proper rate limiting or request throttling, an attacker can flood the API with a large volume of requests, exhausting server resources (CPU, memory, network bandwidth). This can lead to a Denial of Service (DoS) condition, making Chameleon and potentially the entire application unavailable.
  • Likelihood: Medium - APIs are often targets for DoS attacks, and the likelihood depends on the robustness of rate limiting measures.
  • Impact: Medium - Application unavailability, service disruption, impacting A/B testing and feature flag functionality.
  • Effort: Low - Easy to generate a high volume of requests using simple scripts or tools.
  • Skill Level: Low - Basic scripting knowledge is sufficient.
  • Detection Difficulty: Medium - Rate limiting, traffic monitoring, and anomaly detection systems can help detect and mitigate API abuse.

Attack Tree Path: 2.1.1. Access Admin Panel from Public Internet (if not properly restricted) [HR] [CN]

  • Attack Vector: The Chameleon admin panel is accessible from the public internet without proper access restrictions (e.g., IP whitelisting, VPN requirement). This significantly increases the attack surface, making it easier for attackers to discover and exploit any vulnerabilities in the admin panel.
  • Likelihood: Medium - Common misconfiguration, especially in initial deployments or when security is not prioritized.
  • Impact: High - Increased attack surface, easier exploitation of admin panel vulnerabilities, potential for full compromise.
  • Effort: Very Low - Simply accessing the URL of the admin panel from the public internet.
  • Skill Level: Very Low - No specific skills required.
  • Detection Difficulty: Very Easy - Network scans and access logs will easily reveal if the admin panel is publicly accessible.

Attack Tree Path: 2.3.1. Unencrypted Database Credentials [HR] [CN]

  • Attack Vector: Database credentials (username, password) for Chameleon are stored in plaintext in configuration files or environment variables. If an attacker gains access to the server or configuration files (e.g., through other vulnerabilities or misconfigurations), they can easily retrieve these credentials and gain direct access to the Chameleon database.
  • Likelihood: Low to Medium - Common mistake, especially in development or testing environments, or due to lack of security awareness.
  • Impact: Critical - Full database access, potentially leading to data breaches, data manipulation, and further system compromise.
  • Effort: Low - Accessing configuration files or environment variables is often relatively easy if initial access to the server is gained.
  • Skill Level: Low - Basic file system access or system administration knowledge is sufficient.
  • Detection Difficulty: Very Easy - Configuration audits and security scans can easily identify plaintext credentials in configuration files.

Attack Tree Path: 2.4.1. Exploit Known Vulnerabilities in Older Chameleon Versions [HR] [CN]

  • Attack Vector: The application is running an outdated version of Chameleon that contains publicly known security vulnerabilities. Attackers can easily find and exploit these vulnerabilities using readily available exploit code or vulnerability databases, potentially leading to remote code execution or other severe compromises.
  • Likelihood: Medium - Organizations often lag behind in patching software, and known vulnerabilities are easy to exploit.
  • Impact: High to Critical - Depends on the specific vulnerability, but can range from information disclosure to remote code execution and full system compromise.
  • Effort: Low - Exploits are often publicly available for known vulnerabilities, making exploitation straightforward.
  • Skill Level: Low to Medium - Using existing exploits and vulnerability databases requires relatively low skill.
  • Detection Difficulty: Easy - Vulnerability scanners and version checks can easily identify outdated software with known vulnerabilities.

Attack Tree Path: 3.1.1. API Key Leakage in Client-Side Code (if used client-side) [HR]

  • Attack Vector: If Chameleon uses API keys for client-side access, developers might mistakenly embed these API keys directly into client-side JavaScript code. Attackers can easily extract these keys by inspecting the client-side code (e.g., using browser developer tools or decompiling mobile apps).
  • Likelihood: Medium - Common mistake if developers are not security-aware or prioritize ease of development over security.
  • Impact: Medium - Unauthorized API access, potentially allowing attackers to manipulate feature flags, access experiment data, or perform other actions through the API.
  • Effort: Low - Inspecting client-side code and using browser developer tools is very easy.
  • Skill Level: Low - Basic web development knowledge is sufficient.
  • Detection Difficulty: Easy - Code reviews and static analysis tools can easily detect API keys embedded in client-side code.

Attack Tree Path: 3.1.2. API Key Leakage in Server-Side Logs or Configuration [HR]

  • Attack Vector: API keys for Chameleon are unintentionally logged in server-side application logs or stored in plaintext in server-side configuration files. If attackers gain access to these logs or configuration files (e.g., through misconfigurations or other vulnerabilities), they can retrieve the API keys and gain unauthorized API access.
  • Likelihood: Low to Medium - Depends on logging practices and configuration management procedures.
  • Impact: Medium - Unauthorized API access, potentially allowing attackers to manipulate feature flags, access experiment data, or perform other actions through the API.
  • Effort: Low - Accessing logs or configuration files is often relatively easy if initial server access is gained.
  • Skill Level: Low - Basic system administration knowledge is sufficient.
  • Detection Difficulty: Easy - Log analysis and configuration audits can identify API keys in logs or configuration files.

Attack Tree Path: 3.2.1. Abuse API to Exhaust Resources or Cause DoS on Chameleon or Application [HR]

  • Attack Vector: If the Chameleon API lacks proper rate limiting, attackers can abuse the API by sending a large number of requests, overwhelming the server and exhausting resources. This can lead to a Denial of Service (DoS) condition, making the API and potentially the entire application unavailable.
  • Likelihood: Medium - If rate limiting is weak or non-existent, API abuse for DoS is a likely threat.
  • Impact: Medium - API unavailability, potential application impact, disruption of A/B testing and feature flag functionality.
  • Effort: Low - Easy to generate a high volume of API requests using simple scripts or tools.
  • Skill Level: Low - Basic scripting knowledge is sufficient.
  • Detection Difficulty: Medium - Traffic monitoring and anomaly detection systems can help detect API abuse. Rate limiting itself is a primary detection and prevention mechanism.
