CWE-1087: Class with Virtual Method without a Virtual Destructor
A class contains a virtual method, but the method does not have an associated virtual destructor.
How it's found
Class with Virtual Method 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, e.g. due to undefined behavior. 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.
