Nama: Use of Weak Credentials

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.

Konsekuensi Umum

Cakupan	Dampak	Kemungkinan
Access Control	Bypass Protection Mechanism Catatan: When credentials are easily predictable or even fixed (as with default or hard-coded passwords and keys), an adversary could bypass intended authentication restrictions without relying on brute force guessing. Even if a new, unique credential is intended to be generated for each product installation, if the generation is predictable, then that may also simplify guessing attacks.

Referensi	Deskripsi
[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)
CVE-2022-30270	Remote Terminal Unit (RTU) uses default credentials for some SSH accounts
CVE-2022-29965	Distributed Control System (DCS) uses a deterministic algorithm to generate utility passwords
CVE-2022-30271	Remote Terminal Unit (RTU) uses a hard-coded SSH private key that is likely to be used in typical deployments.
CVE-2021-38759	microcontroller board has default password, allowing admin access
CVE-2021-41192	data visualization/sharing package uses default secret keys or cookie values if they are not specified in environment variables
CVE-2020-8994	UART interface for AI speaker uses empty password for root shell
CVE-2020-27020	password manager does not generate cryptographically strong passwords, allowing prediction of passwords using guessable details such as time of generation
CVE-2020-8632	password generator for cloud application has small length value, making it easier for brute-force guessing
CVE-2020-5365	network-attached storage (NAS) system has predictable default passwords for a diagnostics/support account
CVE-2020-5248	IT asset management app has a default encryption key that is the same across installations
CVE-2018-3825	cloud cluster management product has a default master encryption key
CVE-2012-3503	Installation script has a hard-coded secret token value, allowing attackers to bypass authentication
CVE-2010-2306	Intrusion Detection System (IDS) uses the same static, private SSL keys for multiple devices and installations, allowing decryption of SSL traffic
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

Mitigasi yang Memungkinkan

Phases : Architecture and Design // Operation
When the user changes or sets a password, check the password against a database of already compromised or breached passwords. These passwords are likely to be used in password guessing attacks.
