Common Weakness Enumeration
- CWE-261 - Weak Encoding for PasswordObscuring a password with a trivial encoding does not protect the password.
- CWE-326 - Inadequate Encryption StrengthThe 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.
