CVE-2023-21399 - Use of a Broken or Risky Cryptographic Algorithm

Severity

78%

Complexity

18%

Confidentiality

98%

there is a possible way to bypass cryptographic assurances due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

CVSS 3.1 Base Score 7.8. CVSS Attack Vector: local. CVSS Attack Complexity: low. CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

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 It has been replaced by Advanced Encryption Standard (AES).
