Attack Tree Path: 1. Exploit Dependency Vulnerabilities [HIGH RISK PATH]:

  • Compromise json_serializable's Dependencies [CRITICAL NODE]:
    • Attackers target the dependencies of json_serializable (e.g., build_runner, source_gen, analyzer) as a weaker point of entry.
    • Success here can lead to indirect compromise of the application through malicious build processes or generated code.
  • Exploit Vulnerability in Dependency [CRITICAL NODE]:
    • This is the action of actually leveraging a discovered vulnerability in a dependency.
    • This could be a known, publicly disclosed vulnerability or a zero-day.
  • Supply Chain Attack (Dependency Confusion) [HIGH RISK PATH]:
    • Application resolves to malicious package during build [CRITICAL NODE]:
      • Attackers create a malicious package with a name similar to a legitimate dependency.
      • Due to misconfiguration or vulnerabilities in the build process, the application might inadvertently download and use the malicious package instead of the intended one.
      • This allows attackers to inject malicious code into the build process, potentially affecting the generated code or the application itself.
  • Exploit known vulnerability in dependency [CRITICAL NODE]:
    • Attackers leverage publicly available exploits or develop custom exploits for known vulnerabilities in json_serializable's dependencies.
    • Successful exploitation can lead to various impacts, from information disclosure to remote code execution, depending on the specific vulnerability.

Attack Tree Path: 2. Exploit Misuse of Generated Code in Application [HIGH RISK PATH] [CRITICAL THREAT VECTOR]:

  • Application Logic Vulnerabilities related to Deserialized Data [CRITICAL NODE]:
    • This is the most common and easily exploitable attack vector.
    • It arises from vulnerabilities in the application's code that processes data deserialized by json_serializable.
  • Lack of Input Validation on Deserialized Data [HIGH RISK PATH] [CRITICAL NODE]:
    • Assume deserialized data is safe and valid without further checks [CRITICAL NODE - Common Mistake]:
      • Developers often mistakenly assume that data deserialized by json_serializable is inherently safe and valid.
      • This leads to a failure to implement proper input validation.
    • Inject malicious data in JSON payload [CRITICAL NODE - Attack Method]:
      • Attackers craft malicious JSON payloads containing data designed to exploit vulnerabilities in the application logic.
      • This malicious data is deserialized by the generated code and then processed by the vulnerable application logic.
    • Exploit application logic vulnerabilities (e.g., SQL injection, command injection) using malicious data [HIGH RISK PATH] [CRITICAL NODE - Impact]:
      • Due to the lack of input validation, the malicious data from the JSON payload can be used to exploit common application vulnerabilities such as:
        • SQL Injection: Malicious data is used to manipulate SQL queries, potentially leading to data breaches or unauthorized access.
        • Command Injection: Malicious data is used to execute arbitrary commands on the server, potentially leading to complete system compromise.
        • Other application-specific vulnerabilities depending on how the deserialized data is used.

Attack Tree Path: 3. Exploit Build Process Vulnerabilities [MEDIUM RISK PATH]:

  • Compromise Build Environment [CRITICAL NODE]:
    • Attackers target the build environment (developer machines, CI/CD pipelines) to inject malicious code or alter the application during the build process.
  • Compromise Developer Machine [CRITICAL NODE]:
    • Phishing attacks [CRITICAL NODE - Attack Vector]:
      • Attackers use social engineering tactics to trick developers into revealing credentials or installing malware.
    • Malware infection [CRITICAL NODE - Attack Vector]:
      • Attackers use malware (viruses, trojans, etc.) to compromise developer machines, gaining control over their development environment.
    • Gain access to developer's credentials [CRITICAL NODE - Consequence]:
      • Once a developer machine is compromised, attackers can steal developer credentials, allowing them to access other systems and resources, including the CI/CD pipeline and code repositories.
  • Compromise CI/CD Pipeline [CRITICAL NODE]:
    • Exploit vulnerabilities in CI/CD tools [CRITICAL NODE - Attack Vector]:
      • Attackers exploit known vulnerabilities in the CI/CD software itself (e.g., Jenkins, GitLab CI, GitHub Actions).
    • Inject malicious code into CI/CD configuration [CRITICAL NODE - Attack Vector]:
      • Attackers modify the CI/CD pipeline configuration to inject malicious steps or scripts into the build process.
    • Gain access to CI/CD secrets [CRITICAL NODE - Attack Vector]:
      • Attackers steal secrets stored in the CI/CD system (e.g., API keys, deployment credentials), allowing them to tamper with the build or deployment process.
