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
[edit]

Nmap 测试结果：

nmap --script ssl-enum-ciphers -p 443 <IP of the FW>

2. 使用 CLI 命令移除弱密码并实施更改：

admin@FW1# configure
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
set shared ssl-tls-service-profile Cert_Profile protocol-settings auth-algo-sha1 no
set shared ssl-tls-service-profile Cert_Profile protocol-settings auth-algo-sha256 no
set shared ssl-tls-service-profile Cert_Profile protocol-settings enc-algo-3des no
set shared ssl-tls-service-profile Cert_Profile protocol-settings enc-algo-aes-128-cbc no
set shared ssl-tls-service-profile Cert_Profile protocol-settings enc-algo-aes-128-gcm no
set shared ssl-tls-service-profile Cert_Profile protocol-settings enc-algo-rc4 no
set shared ssl-tls-service-profile Cert_Profile protocol-settings keyxchg-algo-dhe no
set shared ssl-tls-service-profile Cert_Profile protocol-settings keyxchg-algo-rsa no

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 。
