CWE-326Inadequate Encryption Strength

Category: data-exposure

Description

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. A weak encryption scheme can be subjected to brute force attacks that have a reasonable chance of succeeding using current attack methods and resources.

Common consequences· 1

  • Access Control / Confidentiality — Bypass Protection Mechanism, Read Application Data
    An attacker may be able to decrypt the data using brute force attacks.

Potential mitigations· 1

  • [Architecture and Design]Use an encryption scheme that is currently considered to be strong by experts in the field.
