Usage of weak hashing library on a password (SHA-1)

• Rule ID: python_lang_weak_password_encryption_sha1
• Languages: python
• Source: weak_password_encryption_sha1.yml

Description

Using a weak hashing library like SHA-1 for passwords increases the risk of data breaches. SHA-1 is vulnerable to collision attacks, where two different inputs can produce the same hash value, compromising data integrity and security.

Remediations

• Do not use SHA-1 for hashing passwords. This algorithm is no longer considered secure and can make your system vulnerable to attacks.

  hashlib.sha1(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
