CWE-1024 不兼容类型的比较

Comparison of Incompatible Types

结构: Simple

Abstraction: Base

状态: Incomplete

被利用可能性: unkown

基本描述

The software performs a comparison between two entities, but the entities are of different, incompatible types that cannot be guaranteed to provide correct results when they are directly compared.

扩展描述

In languages that are strictly typed but support casting/conversion, such as C or C++, the programmer might assume that casting one entity to the same type as another entity will ensure that the comparison will be performed correctly, but this cannot be guaranteed. In languages that are not strictly typed, such as PHP or JavaScript, there may be implicit casting/conversion to a type that the programmer is unaware of, causing unexpected results; for example, the string "123" might be converted to a number type. See examples.
