CVEID:CVE-2023-48795
**DESCRIPTION:**OpenSSH is vulnerable to a machine-in-the-middle attack, caused by a flaw in the extension negotiation process in the SSH transport protocol when used with certain OpenSSH extensions. A remote attacker could exploit this vulnerability to launch a machine-in-the-middle attack and strip an arbitrary number of messages after the initial key exchange, breaking SSH extension negotiation and downgrading the client connection security.
CVSS Base score: 5.9

CVSS Vector: (CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N)

CVEID:CVE-2022-2068
**DESCRIPTION:**OpenSSL could allow a remote attacker to execute arbitrary commands on the system, caused by improper validation of user-supplied input by the c_rehash script. By sending a specially-crafted request using shell metacharacters, an attacker could exploit this vulnerability to execute arbitrary commands with the privileges of the script on the system.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/226018 for the current score.
