CWE-459: Incomplete Cleanup
The product does not properly "clean up" and remove temporary or supporting resources after they have been used.
How it's found
Incomplete Cleanup 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
- Other, Read Application Data, Modify Application Data, DoS: Resource Consumption (Other): It is possible to overflow the number of temporary files because directories typically have limits on the number of files allowed. This could create a denial of service problem.
Mitigations
- Architecture and Design/Implementation: Temporary files and other supporting resources should be deleted/released immediately after they are no longer needed.
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.
