CVSS 3.0 Base Score 8.8. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

CVSS 2.0 Base Score 6.5. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:P/A:P).

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 It has been replaced by Advanced Encryption Standard (AES).
