The kube-rbac-proxy container before version 0.4.1 as used in Red Hat OpenShift Container Platform does not honor TLS configurations, allowing for use of insecure ciphers and TLS 1.0. An attacker could target traffic sent over a TLS connection with a weak configuration and potentially break the encryption.

CVSS 3.0 Base Score 7.5. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).

CVSS 2.0 Base Score 5. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (AV:N/AC:L/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 It has been replaced by Advanced Encryption Standard (AES).
