Nama: Improper Control of Dynamically-Identified Variables

The product does not properly restrict reading from or writing to dynamically-identified variables.

Informasi Umum

Detail Latar Belakang

Mode Pengenalan

Implementation : The dynamic identification of variables can be a powerful, time-saving technique for developers. This practice can reduce maintenance costs because new code would not need to be written for each variable that is managed.

Mitigasi yang Memungkinkan

Phases : Implementation
For any externally-influenced input, check the input against an allowlist of internal program variables that are allowed to be modified.
Phases : Implementation // Architecture and Design
Refactor the code so that internal program variables do not need to be dynamically identified.

Catatan Pemetaan Kerentanan

Justifikasi : This CWE entry is at the Base 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.
