CWE-1108 · Base Level

Description

The code is structured in a way that relies too much on using or setting global variables throughout various points in the code, instead of preserving the associated information in a narrower, more local context.

Potential Impact

Other

Reduce Maintainability, Increase Analytical Complexity

Detection Methods

  • Automated Static Analysis High — 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 sea

Frequently Asked Questions

What is CWE-1108?

CWE-1108 (Excessive Reliance on Global Variables) is a software weakness identified by MITRE's Common Weakness Enumeration. It is classified as a Base-level weakness.
