CWE-326 不充分的加密强度

Inadequate Encryption Strength

结构: Simple

Abstraction: Class

状态: Draft

被利用可能性: unkown

基本描述

The software stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.

扩展描述

A weak encryption scheme can be subjected to brute force attacks that have a reasonable chance of succeeding using current attack methods and resources.

适用平台

Language: {'cwe_Class': 'Language-Independent', 'cwe_Prevalence': 'Undetermined'}

常见的影响

范围 影响 注释
['Access Control', 'Confidentiality'] ['Bypass Protection Mechanism', 'Read Application Data'] An attacker may be able to decrypt the data using brute force attacks.

可能的缓解方案

Architecture and Design

策略:

Use a cryptographic algorithm that is currently considered to be strong by experts in the field.

Notes

Maintenance
A variety of encryption algorithms exist, with various weaknesses. This category could probably be split into smaller sub-categories.
Maintenance
Relationships between CWE-310, CWE-326, and CWE-327 and all their children need to be reviewed and reorganized.
