CWE-1079: Parent Class without Virtual Destructor Method
A parent class contains one or more child classes, but the parent class does not have a virtual destructor method.
How it's found
Parent Class without Virtual Destructor Method 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
- Reduce Reliability: This issue can prevent the product from running reliably due to undefined or unexpected behaviors. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability.
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.
