Неверно настроенный сервер Apache не реализует SSL должным образом - PullRequest

/ 26 мая 2020

Мне нужна помощь в поиске сбоя в моей конфигурации apache2, чтобы мой сервер правильно использовал SSL.

Я написал SSL-клиент, использующий ruby для обслуживания локальных файлов с помощью SSL. Я включил модуль и отредактировал файлы, чтобы включить SSLEngine, но мой сценарий ruby возвращает ошибку, а также сервер при попытке обслуживания моих страниц. Все это выполняется внутри Virtual Box 6.0.20 под управлением Ubuntu 18.04.4 LTS.

Вот скриншот моего Ruby скрипта

Ruby SSL client script

Ошибка, которую я получаю при запуске скрипта через терминал enter image description here

Это ошибка, которую Firefox показывает мне при попытке доступа к моему локальному серверу с помощью SSL (на Ff v76.0.1) Firefox error when requesting / on my local server

Вот файлы, которые, я думаю, могут быть полезны

    #   Server Certificate Chain:

    #   certificate for convinience.

    #   Certificate Authority (CA):
    #   Set the CA certificate verification path where to find CA
    #   certificates for client authentication or alternatively one
    #   huge file containing all of them (file must be PEM encoded)

    #   Certificate Revocation Lists (CRL):

    #   Note: Inside SSLCARevocationPath you need hash symlinks

    #   issuer chain before deciding the certificate is not valid.
    SSLVerifyClient none
    SSLVerifyDepth  1

    #   SSL Engine Options:
    #   Set various options for the SSL engine.
    #   o FakeBasicAuth:
    #    Translate the client X.509 into a Basic Authorisation.  This means that
    #    the standard Auth/DBMAuth methods can be used for access control.  The
    #    user name is the `one line' version of the client's X.509 certificate.
    #    Note that no password is obtained from the user. Every entry in the user
    #    file needs this password: `xxj31ZMTZzkVA'.
    #   o ExportCertData:
    #    This exports two additional environment variables: SSL_CLIENT_CERT and
    #    SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
    #    server (always existing) and the client (only existing when client
    #    authentication is used). This can be used to import the certificates
    #    into CGI scripts.
    #   o StdEnvVars:
    #    This exports the standard SSL/TLS related `SSL_*' environment variables.
    #    Per default this exportation is switched off for performance reasons,
    #    because the extraction step is an expensive operation and is usually
    #    useless for serving static content. So one usually enables the
    #    exportation for CGI and SSI requests only.
    #   o OptRenegotiate:
    #    This enables optimized SSL connection renegotiation handling when SSL
    #    directives are used in per-directory context.
    #SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire
    <FilesMatch "\.(cgi|shtml|phtml|php)$">

    #   SSL Protocol Adjustments:
    #   The safe and default but still SSL/TLS standard compliant shutdown
    #   approach is that mod_ssl sends the close notify alert but doesn't wait for
    #   the close notify alert from client. When you need a different shutdown
    #   approach you can use one of the following variables:
    #   o ssl-unclean-shutdown:
    #    This forces an unclean shutdown when the connection is closed, i.e. no
    #    SSL close notify alert is send or allowed to received.  This violates
    #    the SSL/TLS standard but is needed for some brain-dead browsers. Use
    #    this when you receive I/O errors because of the standard approach where
    #    mod_ssl sends the close notify alert.
    #   o ssl-accurate-shutdown:
    #    This forces an accurate shutdown when the connection is closed, i.e. a
    #    SSL close notify alert is send and mod_ssl waits for the close notify
    #    alert of the client. This is 100% SSL/TLS standard compliant, but in
    #    practice often causes hanging connections with brain-dead browsers. Use
    #    this only for browsers where you know that their SSL implementation
    #    works correctly.
    #   Notice: Most problems of broken clients are also related to the HTTP
    #   keep-alive facility, so you usually additionally want to disable
    #   keep-alive for those clients, too. Use variable "nokeepalive" for this.
    #   Similarly, one has to force some clients to use HTTP/1.0 to workaround
    #   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
    #   "force-response-1.0" for this.
    # BrowserMatch "MSIE [2-6]" \
    #       nokeepalive ssl-unclean-shutdown \
    #       downgrade-1.0 force-response-1.0

Может ли кто-нибудь помочь мне правильно настроить мой сервер с использованием SSL? Сообщите мне о любых других файлах конфигурации, которые необходимо проверить, я просто поместил сюда те, с которыми я больше возился

Заранее спасибо, Альваро

Следующие строки должны быть добавлены в файл .conf вашего сайта, указывая местоположение вашего сертификата и закрытого ключа.

SSLCertificateFile /path/to/your_domain_name.crt SSLCertificateKeyFile / path / to / your_private .key

В моем случае 000-default.conf по умолчанию выглядел так (без комментариев)

<VirtualHost vulnerable:443>

    ServerAdmin sugar@localhost
    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    SSLEngine on
    SSLCertificateFile /etc/apache2/ssl/apache.crt
    SSLCertificateKeyFile /etc/apache2/ssl/apache.key

 </VirtualHost>

После добавления этих строк браузер позволил мне добавить исключение для моего самозаверяющего сертификата, и мой сценарий ruby работал нормально.
