Class Incomplete Simple

CWE版本: 4.18

更新日期: 2025-09-09

弱点描述

The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker.

观察示例

参考: [REF-1374]

Chain: JavaScript-based cryptocurrency library can fall back to the insecure Math.random() function instead of reporting a failure (CWE-392), thus reducing the entropy (CWE-332) and leading to generation of non-unique cryptographic keys for Bitcoin wallets (CWE-1391)

参考: CVE-2022-30270

Remote Terminal Unit (RTU) uses default credentials for some SSH accounts

参考: CVE-2022-29965

Distributed Control System (DCS) uses a deterministic algorithm to generate utility passwords

参考: CVE-2022-30271

Remote Terminal Unit (RTU) uses a hard-coded SSH private key that is likely to be used in typical deployments

参考: CVE-2021-38759

microcontroller board has default password, allowing admin access

参考: CVE-2021-41192

data visualization/sharing package uses default secret keys or cookie values if they are not specified in environment variables

参考: CVE-2020-8994

UART interface for AI speaker uses empty password for root shell

参考: CVE-2020-27020

password manager does not generate cryptographically strong passwords, allowing prediction of passwords using guessable details such as time of generation

参考: CVE-2020-8632

password generator for cloud application has small length value, making it easier for brute-force guessing

参考: CVE-2020-5365

network-attached storage (NAS) system has predictable default passwords for a diagnostics/support account

参考: CVE-2020-5248

IT asset management app has a default encryption key that is the same across installations

参考: CVE-2018-3825

cloud cluster management product has a default master encryption key

参考: CVE-2012-3503

Installation script has a hard-coded secret token value, allowing attackers to bypass authentication

参考: CVE-2010-2306

Intrusion Detection System (IDS) uses the same static, private SSL keys for multiple devices and installations, allowing decryption of SSL traffic

参考: CVE-2001-0618

Residential gateway uses the last 5 digits of the 'Network Name' or SSID as the default WEP key, which allows attackers to get the key by sniffing the SSID, which is sent in the clear
