CWE-1047: Modules with Circular Dependencies
The product contains modules in which one module has references that cycle back to itself, i.e., there are circular dependencies.
How it's found
Modules with Circular Dependencies 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.
As an example, with Java, this weakness might indicate cycles between packages.
Consequences
- Reduce Maintainability: This issue makes it more difficult to maintain the product due to insufficient modularity, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It can also prevent the product from running reliably. If the relevant code is reachable by an attacker, then this reliability 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.
