由于证书握手失败导致的ASA智能许可失败

简介

本文档介绍如何解决2016年3月和2018年10月发生的更改，在更改中，托管tools.cisco.com的Web服务器迁移到不同的根证书颁发机构(CA)证书。迁移后，某些ASA（自适应安全设备）设备在注册ID令牌或尝试更新现有授权时无法连接到智能软件许可门户（托管于tools.cisco.com上）。这被确定为证书相关问题。具体而言，提供给ASA的新证书由与ASA预期不同的中间CA签名，并已预装。

问题

尝试将ASAv注册到智能软件许可门户时，注册失败，连接或通信失败。show license registration和call-home测试配置文件许可证命令显示这些输出。

ASAv# show license registration
        Registration Status: Retry In Progress.
        Registration Start Time: Mar 22 13:25:46 2016 UTC
        Registration Status: Retry In Progress.

        Next Scheduled Retry Time: Mar 22 13:45:31 2016 UTC.

        Last License Server response message: Communication message send response error

ASAv# call-home test profile License
INFO: Sending test message to  https://tools.cisco.com/its/service/oddce/services/DDCEService...
ERROR: Failed: CONNECT_FAILED(35)

但是，ASAv可以解析tools.cisco.com，并通过TCP ping在TCP端口443上连接。

系统日志和调试输出

尝试注册后，ASAv上的系统日志输出将显示：

%ASA-3-717009: Certificate validation failed. No suitable trustpoints found to validate
 certificate serial number: 250CE8E030612E9F2B89F7058FD, subject name:

有关详细信息，请在尝试其他注册时运行这些debug命令。出现安全套接字层错误。

debug license 255
debug license agent all
debug call-home all
debug ssl 255

具体而言，此消息被视为该输出的一部分：

error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify
 failed@s3_clnt.c:1492

在默认ASAv配置中，有一个名为_SmartCallHome_ServerCA的信任点，该信任点已加载证书并颁发给主题名称“cn=Verisign Class 3 Secure Server CA - G3”。

ASAv# show crypto ca certificate

但是，在以前的系统日志中，ASA表示它从智能软件许可门户获得证书，该证书由名为“cn=Symantec Class 3 Secure Server CA - G4”的中间人签名。

注意：主题名称相似，但有两个不同：开头是Verisign与Symantec，结尾是G3与G4。

解决方案

ASAv需要下载包含适当中间和/或根证书的信任池才能验证链。

在版本9.5.2及更高版本中，ASAv的信任池配置为在本地时间晚10:00 PM设备自动导入：

ASAv# sh run crypto ca trustpool
crypto ca trustpool policy
 auto-import
ASAv# sh run all crypto ca trustpool
crypto ca trustpool policy
 revocation-check none
 crl cache-time 60
 crl enforcenextupdate
 auto-import
 auto-import url http://www.cisco.com/security/pki/trs/ios_core.p7b
 auto-import time 22:00:00

如果这是初始安装，并且当时尚未启用域名系统(DNS)查找和Internet连接，则自动导入未成功，需要手动完成。

在较旧版本（如9.4.x）上，未在设备上配置trustpool auto-import，需要手动导入。

在任何版本上，此命令导入信任池和相关证书：

ASAv# crypto ca trustpool import url http://www.cisco.com/security/pki/trs/ios_core.p7b
Root file signature verified.
You are about to update the current trusted certificate pool
with the 17145 byte file at http://www.cisco.com/security/pki/trs/ios_core.p7b
Do you want to continue? (y/n)
Trustpool import:
   attempted:  14
   installed:  14
   duplicates: 0
   expired:    0
   failed:     0

验证

一旦通过手动命令或等待到本地时间晚10:00之后导入trustpool，此命令将验证信任池中是否已安装证书：

ASAv# show crypto ca trustpool policy
14 trustpool certificates installed
Trustpool auto import statistics:
    Last import result: FAILED
    Next scheduled import at 22:00:00 UTC Wed Mar 23 2016
Trustpool Policy
   Trustpool revocation checking is disabled
   CRL cache time: 60 seconds
   CRL next update field: required and enforced
   Automatic import of trustpool certificates is enabled
   Automatic import URL: http://www.cisco.com/security/pki/trs/ios_core.p7b
   Download time: 22:00:00
   Policy Overrides:
      None configured

注意：在上一输出中，上次自动更新导入失败，因为DNS上次自动尝试时未运行，因此它仍将上次自动导入结果显示为失败。但是，手动信任池更新已运行并已成功更新信任池（这就是它显示已安装14个证书的原因）。

安装trustpool后，可以再次运行令牌注册命令，以便向智能软件许可门户注册ASAv。

ASAv# license smart register idtoken id_token force

如果ASAv已注册到智能软件许可门户，但授权续订失败，也可以手动尝试。

ASAv# license smart renew auth 

根CA证书更改 — 2018年10月

tools.cisco.com的根CA证书于2018年10月5日（星期五）更改。 

如果不允许与http://www.cisco.com/security/pki/trs/ios_core.p7b通信，则当前部署的ASAv版本9.6(2)及更高版本以及运行ASA的Firepower 2100将不受此更改的影响。  在前面提到的所有ASA智能许可平台上都默认启用证书自动导入功能。  “show crypto ca trustpool”的输出包含“QuoVadis Root CA 2”证书：

CA Certificate
  Fingerprint: 5e397bddf8baec82e9ac62ba0c54002b
  Issuer Name:
    cn=QuoVadis Root CA 2
    o=QuoVadis Limited
    c=BM     
  Subject Name:
    cn=QuoVadis Root CA 2
    o=QuoVadis Limited
    c=BM

对于新部署，您可以发出“crypto ca trustpool import default”命令并下载包含QuoVadis证书的默认思科证书捆绑包。  如果这不起作用，您可以手动安装证书：

asa(config)# crypto ca trustpoint QuoVadisRootCA2 
asa(config-ca-trustpoint)# enrollment terminal
asa(config-ca-trustpoint)# crl configure
asav(config-ca-crl)# crypto ca authenticate QuoVadisRootCA2 
Enter the base 64 encoded CA certificate.
End with the word "quit" on a line by itself
