JSON decoder accesses a C union using an invalid offset to an object

Mitigasi yang Memungkinkan

Phases : Requirements
The choice could be made to use a language that is not susceptible to these issues.
Phases : Implementation
Review of type casting operations can identify locations where incompatible types are cast.

Metode Deteksi

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.)

Catatan Pemetaan Kerentanan

Justifikasi : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Komentar : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
