Usage of weak hashing library on a password (DSS)

• Rule ID: python_lang_weak_password_hash_dss
• Languages: python
• Source: weak_password_hash_dss.yml

Description

Using a weak hashing library like DSS increases the risk of data breaches. DSS has known security flaws and vulnerabilities, and its use is no longer recommended.

Remediations

• Do not use DSS for hashing passwords as it is considered a weak algorithm. This can compromise data security.

  hashlib.new('dss', user.password).digest() # unsafe

• Do use stronger hashing algorithms such as SHA-256 to enhance the security of stored passwords.

  hashlib.sha256(user.password).digest()

Associated CWE

• CWE-326: Inadequate Encryption Strength

OWASP Top 10

• A02:2021 - Cryptographic Failures
