Expression Issues

A category in the Common Weakness Enumeration published by The MITRE Corporation.


Summary

Categories in the Common Weakness Enumeration (CWE) group entries based on some common characteristic or attribute.

Weaknesses in this category are related to incorrectly written expressions within code.

Weaknesses

Attempt to Access Child of a Non-structure Pointer

Casting a non-structure type to a structure type and accessing a field can lead to memory access errors or data corruption.

Comparison of Object References Instead of Object Contents

The program compares object references instead of the contents of the objects themselves, preventing it from detecting equivalent objects.

Expression is Always False

The software contains an expression that will always evaluate to false.

Expression is Always True

The software contains an expression that will always evaluate to true.

Operator Precedence Logic Error

The program uses an expression in which operator precedence causes incorrect logic to be used.

Use of Incorrect Operator

The programmer accidentally uses the wrong operator, which changes the application logic in security-relevant ways.
