CWE-1091: Use of Object without Invoking Destructor Method
Official CWE-1091 CWE context with Glexia analysis, remediation guidance, related CVEs, and ATT&CK context.
Glexia's Take
CWE-1091: Use of Object without Invoking Destructor Method
Use of Object without Invoking Destructor Method represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Other: Reduce Performance: This issue can make the product perform more slowly by retaining memory and/or other resources longer than necessary. If the relevant code is reachable by an attacker, then this performance problem might introduce a vulnerability.
Developer Pattern
CWE-1091 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
Confidence
high confidence from CWE-1091, 4.20.
Official CWE Definition
CWE-1091: Use of Object without Invoking Destructor Method
The product contains a method that accesses an object but does not later invoke the element's associated finalize/destructor method.
Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- Missing validation
- Unsafe defaults
- Insufficient authorization or memory-safety invariant
Remediation
- Use safe APIs
- Centralize the control
- Add regression tests
- Review logs and telemetry for attempted abuse
Detection
- Automated Static Analysis: Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
