Severity

53%

Complexity

16%

Confidentiality

60%

A missing cryptographic steps vulnerability in the function that encrypts users' LDAP and RADIUS credentials in FortiSandbox before 4.0.1, FortiWeb before 6.3.12, FortiADC before 6.2.1, FortiMail 7.0.1 and earlier may allow an attacker in possession of the password store to compromise the confidentiality of the encrypted secrets.

CVSS 3.1 Base Score 5.3. CVSS Attack Vector: network. CVSS Attack Complexity: high. CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N).

CVSS 2.0 Base Score 2.6. CVSS Attack Vector: network. CVSS Attack Complexity: high. CVSS Vector: (AV:N/AC:H/Au:N/C:P/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 It has been replaced by Advanced Encryption Standard (AES).
