CVSS 3.0 Base Score 5.9. CVSS Attack Vector: network. CVSS Attack Complexity: high. CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).

CVSS 2.0 Base Score 7.1. CVSS Attack Vector: network. CVSS Attack Complexity: medium. CVSS Vector: (AV:N/AC:M/Au:N/C:C/I:N/A:N).

Demo Examples

Use of a Broken or Risky Cryptographic Algorithm

CWE-327

These code examples use the Data Encryption Standard (DES).


               
EVP_des_ecb();

               
des.initEncrypt(key2);

               
}
return $encryptedPassword;

Once considered a strong algorithm, DES now regarded as insufficient for many applications. It has been replaced by Advanced Encryption Standard (AES).
