Connectrix MDS 系列：SSL 或 TLS 服务器支持传输层安全性 TLS1.1

“安全套接字层 （SSL） 或传输层安全性 （TLS） 服务器支持传输层安全性 （TLSv1.1）”

Threat: The scan target supports version 1.1 of the TLS protocol. That version is in the process of being deprecated and is no longer recommended. Instead the newer versions 1.2 and/or 1.3 should be used. The TLSv1.1 protocol itself does not have any currently exploitable vulnerabilities. However some vendor implementations of TLSv1.1 have weaknesses which may be exploitable. This QID is posted as potential, when servers require client certificates and we cannot complete the handshake.

Results: 支持 TLSv1.1。

Solution: Disable the use of TLSv1.1 protocol in favor of a cryptographically stronger protocol such as TLSv1.2.
The following openssl commands can be used to do a manual test: openssl s_client -connect ip:port -tls1_1
If the test is successful, then the target support TLSv1.1.

捕获以下交换机命令的输出：

`show file volatile:///nxapi.log`

HTTPS port is 8443
Options gathered - vdc: 1, servers: 4, http: -1, https: 8443,
cert: /var/nginx/cert/server.crt_vdc_1, key: /var/nginx/cert/server.key_vdc_1, sandbox: false, protocols: TLSv1.2, ciphers: false

这意味着在交换机上禁用 TLS 1.0 和 1.1，并启用 TLSv1.2。因此，该漏洞可以被判定为误报。

如果它仍接受 TLSv1 和 TLSv1.1，您可以手动配置使用的 TLS 版本：

switch(config)# nxapi ssl protocols TLSv1.2          <--To enable TLSv1.2

switch(config)# no nxapi ssl protocols TLSv1         <--To disable TLSv1-disabling TLSv1 removes TLS 1.0 and 1.1.
