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.
Last updated
Overview
CWE-1045 (Parent Class with a Virtual Destructor and a Child Class without a Virtual Destructor) is a base-level software weakness catalogued by MITRE in the Common Weakness Enumeration (CWE). It describes a recurring type of mistake that can lead to exploitable security vulnerabilities.
Common consequences
What can happen when CWE-1045 is exploited.
Reduce Reliability
Affects: Other
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).
