CWE-1082: Class Instance Self Destruction Control Element
Learn about CWE-1082 (Class Instance Self Destruction Control Element), its security impact, exploitation methods, and prevention guidelines.
What is Class Instance Self Destruction Control Element?
• Overview: Class Instance Self Destruction Control Element is a vulnerability where an object or class instance contains code that allows it to delete or destroy itself, such as using "delete this" in C++. This can lead to unpredictable behavior and potential security vulnerabilities if an attacker can influence the execution flow.
• Exploitation Methods:
- Attackers can exploit this vulnerability by manipulating the program to trigger the self-destructing code path, potentially leading to a denial of service.
- Common attack patterns include crafting inputs or requests that cause the self-deleting method to execute unexpectedly.
• Security Impact:
- Direct consequences include application crashes and unexpected behavior, which can lead to denial of service.
- Potential cascading effects include data corruption or loss if the self-destruction interferes with critical operations.
- Business impact involves reduced reliability and trust in the software, potential data loss, and increased maintenance costs.
• Prevention Guidelines:
- Specific code-level fixes include avoiding the use of self-deleting code patterns such as "delete this" and ensuring proper object lifecycle management.
- Security best practices involve implementing thorough code reviews and testing to identify and eliminate self-destruct patterns.
- Recommended tools and frameworks include static analysis tools that can detect unsafe code patterns and utilizing design patterns that separate memory management from business logic.
