适用于

  • ONTAP 9.9.0 及更高版本
  • 传输层安全性 (TLS)
  • Qualys ID 38794

问题描述

  • 安全扫描报告显示了集群中某个 IP 的漏洞,表明启用了较旧的 TLS 版本:

vulnerability(ies): Secure Sockets Layer/Transport Layer Security (SSL/TLS) Server Supports Transport Layer Security (TLSv1.1)

  • 但是,从集群中看不到该 TLS 版本:

Cluster::> set advanced
Cluster::*> security config show -fields supported-protocols
interface supported-protocols
--------- -------------------
SSL    TLSv1.2, TLSv1.3

  • Linux 主机受影响 IP 的 nmap 输出列出了较旧 TLS 版本的密码:

Linux@Host# nmap -sV --script ssl-enum-ciphers.nse -p 443 10.XX.XX.XXX

Starting Nmap 5.51 ( http://nmap.org ) at 2023-05-17 09:12 PDT
Nmap scan report for user.group.com (10.XX.XX.XXX)
Host is up (0.0011s latency).
