CWE-833: Deadlock
The product contains multiple threads or executable segments that are waiting for each other to release a necessary lock, resulting in deadlock.
How it's found
Deadlock is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
Consequences
- DoS: Resource Consumption (CPU), DoS: Resource Consumption (Other), DoS: Crash, Exit, or Restart: Each thread of execution will "hang" and prevent tasks from completing. In some cases, CPU consumption may occur if a lock check occurs in a tight loop.
Where this fits in a TurboPentest engagement
TurboPentest's agentic pentest is powerful and covers a broad range of issues automatically. This particular class is best confirmed in a manual IntegSec engagement, where human pentesters apply deeper methodology and a larger context window than any automated pass.
