Weakness
CWE-324: Use of a Key Past its Expiration Date
The product uses a cryptographic key or password past its expiration date, which diminishes its safety significantly by increasing the timing window for cracking attacks against that key.
How to prevent it
- Architecture and Design: Adequate consideration should be put in to the user interface in order to notify users previous to the key's expiration, to explain the importance of new key generation and to walk users through the process as painlessly as possible.
CWE-326: Inadequate Encryption Strength
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
How to prevent it
- Architecture and Design: Use an encryption scheme that is currently considered to be strong by experts in the field.
