CWE-1048: Invokable Control Element with Large Number of Outward Calls
The code contains callable control elements that contain an excessively large number of references to other application objects external to the context of the callable, i.e. a Fan-Out value that is excessively large.
How it's found
Invokable Control Element with Large Number of Outward Calls 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.
While the interpretation of "excessively large Fan-Out value" may vary for each product or developer, CISQ recommends a default of 5 referenced objects.
Consequences
- Reduce Maintainability, Increase Analytical Complexity: This issue makes it more difficult to maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.
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.
