Attack Tree Analysis for reactivex/rxkotlin

Objective: Compromise Application Using RxKotlin

Attack Tree Visualization

  • Attack Goal: Compromise Application Using RxKotlin [CRITICAL NODE]
      1. Exploit Reactive Logic Flaws [HIGH-RISK PATH START]
      • 1.1. Operator Misuse & Logic Errors [CRITICAL NODE]
        • 1.1.1. Data Leakage via Incorrect Filtering/Mapping [HIGH-RISK PATH]
          • Exploit: Observe unintended data exposure due to flawed operator logic.
        • 1.1.2. Business Logic Bypass via Stream Manipulation [HIGH-RISK PATH] [CRITICAL NODE]
          • Exploit: Circumvent security checks by manipulating data flow in reactive streams.
        • 1.1.4. Vulnerabilities in Custom Operators (if any) [CRITICAL NODE]
          • Exploit: Target vulnerabilities introduced in custom RxKotlin operators.
        1. Exploit Reactive Logic Flaws [HIGH-RISK PATH END]
      1. Abuse Concurrency & Scheduling [HIGH-RISK PATH START]
      • 2.1. Scheduler Exhaustion & Denial of Service (DoS) [HIGH-RISK PATH] [CRITICAL NODE]
        • 2.1.1. Unbounded Schedulers & Resource Starvation [HIGH-RISK PATH] [CRITICAL NODE]
          • Exploit: Flood the application with requests that trigger unbounded reactive streams, exhausting scheduler resources (threads, memory).
        • 2.1.2. Blocking Operations in Schedulers [HIGH-RISK PATH]
          • Exploit: Introduce blocking operations within reactive streams that are executed on shared schedulers, causing thread pool starvation and DoS.
      • 2.2.2. Deadlocks in Reactive Flows [CRITICAL NODE]
        • Exploit: Craft reactive flows that create deadlock situations due to improper synchronization or resource contention.
        1. Abuse Concurrency & Scheduling [HIGH-RISK PATH END]
      1. Exploit Error Handling Weaknesses [HIGH-RISK PATH START]
      • 3.1. Information Disclosure via Error Messages [HIGH-RISK PATH] [CRITICAL NODE]
        • 3.1.1. Verbose Error Logging in Reactive Streams [HIGH-RISK PATH] [CRITICAL NODE]
          • Exploit: Trigger errors in reactive streams to expose sensitive information through overly verbose error logs.
        • 3.1.2. Unhandled Exceptions Leaking Internal Details [HIGH-RISK PATH] [CRITICAL NODE]
          • Exploit: Cause unhandled exceptions in reactive streams that reveal internal application paths, configurations, or dependencies in error responses.
        1. Exploit Error Handling Weaknesses [HIGH-RISK PATH END]
      1. Backpressure Exploitation [HIGH-RISK PATH START]
      • 4.1. Backpressure Bypass & Resource Overload [HIGH-RISK PATH] [CRITICAL NODE]
        • 4.1.1. Ignoring Backpressure Signals [HIGH-RISK PATH] [CRITICAL NODE]
          • Exploit: Flood the application with data exceeding processing capacity if backpressure signals are ignored, leading to resource exhaustion.
        1. Backpressure Exploitation [HIGH-RISK PATH END]
      1. Dependency Vulnerabilities (Indirect RxKotlin Threat) [HIGH-RISK PATH START] [CRITICAL NODE]
      • 5.1. Vulnerabilities in RxKotlin's Dependencies [HIGH-RISK PATH] [CRITICAL NODE]
        • 5.1.1. Transitive Dependency Vulnerabilities [HIGH-RISK PATH] [CRITICAL NODE]
          • Exploit: Leverage known vulnerabilities in libraries that RxKotlin depends on transitively.
