Weak encryption High

DES encryption uses keys of 56 bits only. Switch to AesCryptoServiceProvider or RijndaelManaged instead.

To fix the problem, we need to replace the use of DESCryptoServiceProvider with AesCryptoServiceProvider, which implements the AES algorithm. AES is a widely accepted standard for encryption and provides a much higher level of security compared to DES.

  • General Fix: Replace DESCryptoServiceProvider with AesCryptoServiceProvider and ensure the key length is appropriate for AES (128, 192, or 256 bits).
  • Detailed Fix: Update the BadEncryptionService class to use AesCryptoServiceProvider. Generate a new key and initialization vector (IV) suitable for AES. Ensure the encryption and decryption processes are updated accordingly.

To fix the SQL injection vulnerability, we should use parameterized queries instead of string concatenation. This approach ensures that user input is treated as a parameter and not as part of the SQL command, thus preventing SQL injection attacks.

  • Replace the string concatenation with a parameterized query.
  • Use the Dapper library's parameterized query feature to safely include the user input in the SQL query.
  • Modify the query to use a parameter placeholder (@name) and pass the user input as a parameter.
