CWE-665: Improper Initialization

ID CWE-665

Abstraction Class

Structure Simple

Status Draft

Number of CVEs 310

The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.

This can have security implications when the associated resource is expected to have certain properties or values, such as a variable that determines whether a user has been authenticated or not.

Modes of Introduction

Phase	Note
Implementation	This weakness can occur in code paths that are not well-tested, such as rare error conditions. This is because the use of uninitialized data would be noticed as a bug during frequently-used functionality.
