Attack Tree Analysis for crossbeam-rs/crossbeam

Objective: Compromise Application via Crossbeam Exploitation

Attack Tree Visualization

• Exploit Concurrency Bugs Introduced by Crossbeam Usage [HIGH RISK PATH]
  • Data Races/Race Conditions [HIGH RISK PATH]
    • AND
      • Identify shared mutable state accessed by Crossbeam primitives (channels, scopes, atomics, queues)
      • Trigger concurrent access to shared state in a vulnerable order
        • Example: Send/Receive on unbounded channel leading to unexpected state changes
        • Example: Incorrect atomic operation sequence leading to logical errors
  • Deadlocks/Livelocks [HIGH RISK PATH] [CRITICAL NODE]
    • AND
      • Identify potential deadlock scenarios in Crossbeam usage (e.g., channel dependencies, mutex locking order)
      • Trigger deadlock condition by manipulating application state or input
        • Example: Circular channel dependencies in message passing
        • Example: Incorrect locking order when using Crossbeam's mutexes or channels with internal locking
  • Resource Exhaustion (DoS) via Concurrency Features [HIGH RISK PATH] [CRITICAL NODE]
    • AND
      • Identify Crossbeam features susceptible to resource exhaustion (e.g., unbounded channels, excessive thread creation)
      • Exploit feature to consume excessive resources (CPU, memory, threads)
        • Example: Flooding an unbounded channel to cause memory exhaustion
        • Example: Rapidly spawning scoped threads without proper resource limits
  • Logic Errors in Concurrent Logic [HIGH RISK PATH]
    • AND
      • Understand the application's concurrent logic implemented with Crossbeam
      • Manipulate input or application state to trigger unexpected behavior due to flawed concurrent logic
        • Example: Incorrect message handling order in a channel-based system leading to data corruption
        • Example: Flawed state management in scoped threads causing inconsistent application behavior
