CWE-1091: Use of Object without Invoking Destructor Method
Learn about CWE-1091 (Use of Object without Invoking Destructor Method), its security impact, exploitation methods, and prevention guidelines.
What is Use of Object without Invoking Destructor Method?
• Overview: Use of Object without Invoking Destructor Method (CWE-1091) occurs when an object is used in a program, but its destructor or finalize method is not called, leading to potential resource management issues.
• Exploitation Methods:
- Attackers can exploit this by causing the application to consume excessive resources, potentially leading to denial of service.
- Common attack patterns include intentionally preventing destructors from being invoked to exhaust system resources or degrade performance.
• Security Impact:
- Direct consequences include increased memory usage, resource leaks, and potential application slowdowns.
- Potential cascading effects include system instability and reduced availability of resources for legitimate users.
- Business impact might involve increased operational costs, customer dissatisfaction, and potential downtime.
• Prevention Guidelines:
- Specific code-level fixes include ensuring destructors are invoked either explicitly or through language features that manage object lifecycles.
- Security best practices involve regular code reviews to identify and rectify resource management issues.
- Recommended tools and frameworks include static analysis tools that can detect objects not properly finalized and memory profiling tools to monitor resource usage.
