Безопасность

Важная информация никогда не должна храниться или передаваться в куках HTTP, поскольку этот механизм сам по себе небезопасен.

Куки часто используются в веб-приложениях для идентификации пользователя и сеанса работы, в котором он прошёл процедуру аутентификации. Соответственно, похищение куков из приложения может привести к захвату авторизованного сеанса пользователя. Кража куков часто осуществляется посредством социальной инженерии (Social Engineering) и использования уязвимости приложения для XSS (en-US).

Атрибут HttpOnly помогает понизить эту угрозу, перекрывая доступ к кукам из JavaScript..

В  приведён хороший пример CSRF. В сообщение (например, в чате или на форуме) включают (якобы) изображение, которое, на самом деле, представляет собой запрос к банковскому серверу на снятие денег:

Теперь, если вы зашли в свой банковский аккаунт, а куки по-прежнему действительны (и никакой дополнительной проверки не требуется), то при загрузке HTML-документа с этим изображением деньги будут переведены с вашего счета. Для защиты от этого используется ряд методов:

Как и при XSS (en-US), важна фильтрация входящей информации.
Для любой важной операции должно запрашиваться подтверждение.
Куки, используемые для ответственных операций, должны иметь короткий срок действия.
Дополнительную информацию можно получить в пользовательской инструкции по предотвращению OWASP CSRF.

Tracking and privacy

A cookie is associated with a domain. If this domain is the same as the domain of the page you are on, the cookie is called a first-party cookie. If the domain is different, it is a third-party cookie. While the server hosting a web page sets first-party cookies, the page may contain images or other components stored on servers in other domains (for example, ad banners), which may set third-party cookies. These are mainly used for advertising and tracking across the web. See for example the types of cookies used by Google.

A third-party server can build up a profile of a user’s browsing history and habits based on cookies sent to it by the same browser when accessing multiple sites. Firefox, by default, blocks third-party cookies that are known to contain trackers. Third-party cookies (or just tracking cookies) may also be blocked by other browser settings or extensions. Cookie blocking can cause some third-party components (such as social media widgets) to not function as intended.

Note: Servers can (and should) set the cookie SameSite attribute to specify whether or not cookies may be sent to third party sites.

Legislation or regulations that cover the use of cookies include:

  • The General Data Privacy Regulation (GDPR) in the European Union
  • The ePrivacy Directive in the EU
  • The California Consumer Privacy Act

These regulations have global reach, because they apply to any site on the World Wide Web that is accessed by users from these jurisdictions (the EU and California, with the caveat that California’s law applies only to entities with gross revenue over 25 million USD, among other things.)

These regulations include requirements such as:

  • Notifying users that your site uses cookies.
  • Allowing users to opt out of receiving some or all cookies.
  • Allowing users to use the bulk of your service without receiving cookies.

There may be other regulations governing the use of cookies in your locality. The burden is on you to know and comply with these regulations. There are companies that offer «cookie banner» code that helps you comply with these regulations.

Other ways to store information in the browser

Another approach to storing data in the browser is the Web Storage API. The window.sessionStorage and window.localStorage properties correspond to session and permanent cookies in duration, but have larger storage limits than cookies, and are never sent to a server. More structured and larger amounts of data can be stored using the IndexedDB API, or a library built on it.

Other techniques have been created to cause cookies to be recreated after they are deleted, known as «zombie» cookies. These techniques violate the principles of user privacy and user control, may violate data privacy regulations, and could expose a website using them to legal liability.

Notes

  • Starting with Firefox 2, a better mechanism for client-side storage is available —
    WHATWG DOM Storage.
  • You can delete a cookie by updating its expiration time to zero.
  • Keep in mind that the more cookies you have, the more data will be transferred
    between the server and the client for each request. This will make each request
    slower. It is highly recommended for you to use WHATWG DOM Storage if you are going to keep
    «client-only» data.
  • RFC 2965 (Section 5.3,
    «Implementation Limits») specifies that there should be no maximum
    length of a cookie’s key or value size, and encourages
    implementations to support arbitrarily large cookies. Each
    browser’s implementation maximum will necessarily be different, so consult
    individual browser documentation.

The reason for the of the
accessor property is due to the client-server nature of cookies, which differs from
other client-client storage methods (like, for instance, localStorage):

The server tells the client to
store a cookie

The client
sends back to the server its cookies previously stored

Content-type: text/html
Set-Cookie: cookie_name1=cookie_value1
Set-Cookie: cookie_name2=cookie_value2; expires=Sun, 16 Jul 3567 06:23:41 GMT

The client sends back to the server its cookies previously stored
GET /sample_page.html HTTP/1.1
Host: www.example.org
Cookie: cookie_name1=cookie_value1; cookie_name2=cookie_value2
Accept: */*

The parameter of a new cookie can accept only absolute paths. If you want to use relative paths, therefore, you need to convert them. The following function can translate relative paths to absolute paths. It is a general-purpose function, but can be of course successifully used for the parameter of a new cookie, as well.

Sample usage

If you don’t want to use an absolute date for the parameter, here you can find some numeric examples of expiration-dates relative to the moment of storage of the cookie:

Функционал, для которого зачастую требуется cookies

Без кукисов не обходится:

  • авторизация на сайте – если вы зайдёте на сайт, введёте свои данные для входа, то по возвращению сайт вас «узнает».
  • опросы и голосования – для предотвращения «накрутки» зачастую используются кукисы, в которых сохраняется соответствующая информация.
  • индивидуальные настройки отображения сайта – некоторые сайты позволяют индивидуально настроить выводимые блоки, дизайн и т.п. Вся эта информация сохраняется в кукисах браузера.
  • для статистики – сайт по сохранённым кукисам может определить, новый вы пользователь или вернувшийся. Статистика очень помогает создателям сайтов, дабы оценить качество ресурса и его популярность.
  • в рекламных целях – да, для этого кукисов тоже очень часто используются. Вы, наверное, заметили, что если вы ранее что-то искали в популярном интернет поисковике, то впоследствии вам на самых разных сайтах показывается «тематическая» реклама.
  • бан на сайте – для ограничения доступа к сайту в некоторых случаях используются кукисы.

Как видите, предназначение у кукисов самое разное. И если вы хотите посмотреть сохранённые кукисы, выборочно удалять, а также добавлять свои кукис-записи, то это вполне реально.

Safari 5.1 and later

  1. In Safari, from the Safari menu, select Preferences….
  2. In the Safari preferences window, click Privacy.

    • To manage cookie settings, next to «Block cookies», select From
      third parties and advertisers, Always, or Never.

  2. In the Safari preferences window, click Security.

    • To manage cookie settings, next to «Accept Cookies:», select Always or Only from sites you navigate to. To disable cookies, select Never.
    • To view and delete individual cookies, click Show
      Cookies. In the sheet that drops down, you can browse the list of cookies on your computer.
    • To delete all cookies, click Show Cookies. In the window that appears, select Remove All.

Security

Note: Information should be stored in cookies with the understanding that all cookie values are visible to, and can be changed by, the end-user. Depending on the application, it may be desirable to use an opaque identifier, which is looked up by the server or to investigate alternative authentication/confidentiality mechanisms such as JSON Web Tokens.

Ways to mitigate attacks involving cookies:

  • Use the attribute to prevent access to cookie values via JavaScript.
  • Cookies that are used for sensitive information (such as indicating authentication) should have a short lifetime, with the attribute set to or . (See , above.) In , this has the effect of ensuring that the authentication cookie is not sent with cross-site requests, so such a request is effectively unauthenticated to the application server.

Cookie import and export from Kameleo

In the Profile window under the Tools menu, you can find the Cookie Import & Export feature. Once you click it you will see the cookies of your profile.

You can browse your cookies with ease. You can filter the cookies as well.

Export Cookies from Kameleo

Once you selected the required cookies you can simply click export. Depending on your selection the cookies will be exported to your clipboard or into a file. The cookies exported by Kameleo will have the following .json format:

[      {          "domain": "mail.google.com",          "name": "COMPASS",          "path": "/mail",          "value": "gmail=hjlasdflsdafmsakdfasdikads3f",          "hostOnly": false,          "httpOnly": true,          "secure": true,          "sameSite": "unspecified",          "session": false,          "storeId": "0",          "expirationDate": 1568986993      } ]

This format is compatible with all the popular cookie tools. For example Edit This Cookie add-on.

Import Cookies to Kameleo

If you already have cookies that you would like to import to Kameleo you can simply do it with the Cookie Import & Export tool of Kameleo.

You can import the cookies from the clipboard or from a JSON file. The format is the same as for export, so it is compatible with all the popular cookie import and export tools like Edit This Cookie.

If you are importing cookies for a domain that already contains cookies for the profile you will be prompted with the message: «There are already cookies in your profile for the following domains: … Do you want to override them?»

In case if you click No, nothing will happen. If you click Yes your current cookies will be overridden with the new ones.

Warning

In some cases, you can see error messages once you open the Cookie Import & Export dashboard. Something like: «Couldn’t load cookies. Unable to open database file».

This happens if you’re working with a brand new profile that has never been started or an old profile that was created with an older version of Kameleo. What you only have to do is:

  1. Start the browser
  2. Wait about 10 seconds
  3. Close the browser
  4. Try to open cookies again

Most likely it will solve the problem and you will be able to open the Cookie Import & export tool for your Kameleo Profile.

Security

It is important to note that the attribute does not protect
against unauthorized reading of the cookie from a different path. It can be easily
bypassed using the DOM, for example by creating a hidden
element with the path of the cookie, then accessing this iframe’s
property. The only way to protect the cookie is by
using a different domain or subdomain, due to the same origin policy.

Cookies are often used in web applications to identify a user and their authenticated
session. Stealing a cookie from a web application leads to hijacking the
authenticated user’s session. Common ways to steal cookies include using social
engineering or by exploiting a cross-site scripting (XSS) vulnerability in the application —

The cookie attribute can help to mitigate this attack by
preventing access to cookie value through Javascript. Read more about Cookies and
Security.

Отслеживание и частные данные

Куки связаны с определённым доменом. Если он совпадает с доменом страницы, на которой вы находитесь, то их называют «куками первого лица» (first-party cookies). Если это другой домен, их называют «сторонними куками» (third-party cookies). Куки первого лица отсылаются только на тот сервер, который их создал. Однако, страница может содержать изображения или другие компоненты (например, рекламные баннеры), хранящиеся на других серверах. Куки, посылаемые через такие компоненты, используются, главным образом, в рекламных целях или для отслеживания информации в сети. В качестве примера можно рассмотреть типы файлов cookie, используемые Google. Большинство браузеров по умолчанию разрешают использование сторонних куков, но есть расширения, позволяющие их блокировать (например, Privacy Badger от EFF).

Если вы не сообщите об использовании сторонних куков, а пользователь обнаружит их самостоятельно, то доверие к вам может пошатнуться. Чтобы избежать этого, лучше предоставлять соответствующую информацию. В некоторых странах использование куков регламентируется законодательством. Прочитать об этом можно, например, в Википедии в разделе cookie statement (создание куков).

Для запрета на отслеживание со стороны приложения, или межсайтового отслеживания, можно использовать заголовок , хотя технических или законодательных требований на этот счёт нет. Подробнее об этом рассказывается в разделе заголовок .

Правила по использованию куков в Евросоюзе (ЕС) определены в Директиве 2009/136/EC Европарламента (Directive 2009/136/EC), вступившей в действие 25 мая 2011. Это не закон, как таковой, а рекомендация странам-членам ЕС принять законы, соответствующие её требованиям. В каждой стране на этот счёт могут быть свои законы.

Согласно этой директиве для хранения или извлечения информации с компьютера пользователя требуется проинформировать его и получить соответствующее разрешение. С момента её появления многие сайты добавили баннеры, информирующие пользователя об использовании куков.

Подробнее об этом можно прочитать в соответствующем разделе Википедии (). За наиболее полной и точной информацией обращайтесь к законодательствам конкретных стран.

Более радикальный подход к кукам представляют собой куки-зомби, или «вечные» куки, которые восстанавливаются после удаления, и полное удаление которых умышленно затруднено. Они используют прикладные интерфейсы веб-хранилищ (Web storage API), Flash Local Shared Objects и другие методы собственного воссоздания в случае, если обнаружено их отсутствие.

  • Zombie cookies on Wikipedia

Examples

Session cookies are removed when the client shuts down. Cookies are session cookies if they don’t specify the or attributes.

Set-Cookie: sessionId=38afes7a8

Instead of expiring when the client is closed, permanent cookies expire at a specific date () or after a specific length of time ().

Set-Cookie: id=a3fWa; Expires=Wed, 21 Oct 2015 07:28:00 GMT
Set-Cookie: id=a3fWa; Max-Age=2592000

A cookie for a domain that does not include the server that set it .

The following cookie will be rejected if set by a server hosted on :

Set-Cookie: qwerty=219ffwef9w0f; Domain=somecompany.co.uk

A cookie for a sub domain of the serving domain will be rejected.

The following cookie will be rejected if set by a server hosted on :

Set-Cookie: sessionId=e8bb43229de9; Domain=foo.example.com

Cookies names prefixed with or can be used only if they are set with the attribute from a secure (HTTPS) origin.

In addition, cookies with the prefix must have a path of (meaning any path at the host) and must not have a attribute.

Warning: For clients that don’t implement cookie prefixes, you cannot count on these additional assurances, and prefixed cookies will always be accepted.

// Both accepted when from a secure origin (HTTPS)
Set-Cookie: __Secure-ID=123; Secure; Domain=example.com
Set-Cookie: __Host-ID=123; Secure; Path=/

// Rejected due to missing Secure attribute
Set-Cookie: __Secure-id=1

// Rejected due to the missing Path=/ attribute
Set-Cookie: __Host-id=1; Secure

// Rejected due to setting a Domain
Set-Cookie: __Host-id=1; Secure; Path=/; Domain=example.com

domain

A domain defines where the cookie is accessible. In practice though, there are limitations. We can’t set any domain.

By default, a cookie is accessible only at the domain that set it. So, if the cookie was set by , we won’t get it at .

…But what’s more tricky, we also won’t get the cookie at a subdomain !

There’s no way to let a cookie be accessible from another 2nd-level domain, so will never receive a cookie set at .

It’s a safety restriction, to allow us to store sensitive data in cookies, that should be available only on one site.

…But if we’d like to allow subdomains like to get a cookie, that’s possible. When setting a cookie at , we should explicitly set the option to the root domain: :

For historical reasons, (a dot before ) also works the same way, allowing access to the cookie from subdomains. That’s an old notation and should be used if we need to support very old browsers.

So, the option allows to make a cookie accessible at subdomains.
