CWE-606: Unchecked Input for Loop Condition
The product does not properly check inputs that are used for loop conditions, potentially leading to a denial of service or other consequences because of excessive looping.
How it's found
Unchecked Input for Loop Condition 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)
Mitigations
- Implementation: Do not use user-controlled data for loop conditions.
- Implementation: Perform input validation.
Where this fits in a TurboPentest engagement
This weakness is not covered by the automated black-box pentest. IntegSec pentesters cover it in a manual engagement.
