禁用用于 Web 访问的弱密码 GUI 不起作用

Symptom
禁用弱密码 SSL / TLS 服务配置文件不会禁用用于 Web GUI 访问的密码。
这可以通过使用 nmap 工具使用命令来列举 ssl 密码来验证：
nmap --script ssl-enum-ciphers -p 443 <Firewall IP Address>
示例：
1. 在尝试禁用弱密码之前：
admin@FW1# show shared ssl-tls-service-profile Cert_Profile protocol-settings
set shared ssl-tls-service-profile Cert_Profile protocol-settings min-version tls1-2
set shared ssl-tls-service-profile Cert_Profile protocol-settings max-version max

3. Nmap 测试结果显示提交后密码没有更改：
nmap --script ssl-enum-ciphers -p 443 <IP of the FW>

Environment
- 任何帕洛阿尔托 Firewall 。
- 任何 Panorama .
- PAN-OS 版本低于 9.0.11 （9.0.x）。
- PAN-OS 版本低于9.1.5（9.1.x）。
- PAN-OS 版本低于 10.0.1 （10.0.x）。
Cause
这些命令仅适用于 GlobalProtect SSL 正在使用/配置文件的接口（门户/网关 TLS ）。
Resolution
升级到 PAN-OS 9.0.11版本（或9.1.5/10.0.1）及以上。
从 PAN-OS 版本 10.0.1、9.1.5 和 9.0.11 开始，这些命令也将应用于管理界面。
此更改已记录在 以下发布说明 中 PAN-115541 。
