CWE-1045: Parent Class with a Virtual Destructor and a Child Class without a Virtual Destructor
A parent class has a virtual destructor method, but the parent has a child class that does not have a virtual destructor.
How it's found
Parent Class with a Virtual Destructor and a Child Class without a Virtual Destructor 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, since the child might not perform essential destruction operations. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability, such as a memory leak (CWE-401).
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.
