CWE-1043: Data Element Aggregating an Excessively Large Number of Non-Primitive Elements
The product uses a data element that has an excessively large number of sub-elements with non-primitive data types such as structures or aggregated objects.
How it's found
Data Element Aggregating an Excessively Large Number of Non-Primitive Elements 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" may vary for each product or developer, CISQ recommends a default of 5 sub-elements.
Consequences
- Reduce Performance: This issue can make the product perform more slowly. If the relevant code is reachable by an attacker, then this performance problem might introduce a vulnerability.
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.
