Security Advisories 🚨

🚨 Potential XSS vulnerability in jQuery

Impact

Passing HTML containing <option> elements from untrusted sources - even after
sanitizing them - to one of jQuery's DOM manipulation methods (i.e. .html(),
.append(), and others) may execute untrusted code.

Workarounds

To workaround this issue without upgrading, use DOMPurify with its
SAFE_FOR_JQUERY option to sanitize the HTML string before passing it to a
jQuery method.

🚨 Prototype pollution attack through jQuery $.extend

jQuery before 3.4.0 mishandles jQuery.extend(true, {}, ...) because of
bject.prototype pollution. If an unsanitized source object contained an
enumerable proto property, it could extend the native Object.prototype.

Security Advisories 🚨

🚨 Percent-encoded cookies can be used to overwrite existing prefixed cookie names

It is possible to forge a secure or host-only cookie prefix in Rack using
an arbitrary cookie write by using URL encoding (percent-encoding) on the
name of the cookie. This could result in an application that is dependent on
this prefix to determine if a cookie is safe to process being manipulated
into processing an insecure or cross-origin request.
This vulnerability has been assigned the CVE identifier CVE-2020-8184.

Versions Affected: rack < 2.2.3, rack < 2.1.4
Not affected: Applications which do not rely on __Host- and __Secure- prefixes to determine if a cookie is safe to process
Fixed Versions: rack >= 2.2.3, rack >= 2.1.4

Impact

An attacker may be able to trick a vulnerable application into processing an
insecure (non-SSL) or cross-origin request if they can gain the ability to write
arbitrary cookies that are sent to the application.

Workarounds

If your application is impacted but you cannot upgrade to the released versions or apply
the provided patch, this issue can be temporarily addressed by adding the following workaround:

module Rack
  module Utils
    module_function def parse_cookies_header(header)
      return {} unless header
      header.split(/[;] */n).each_with_object({}) do |cookie, cookies|
        next if cookie.empty?
        key, value = cookie.split('=', 2)
        cookies[key] = (unescape(value) rescue value) unless cookies.key?(key)
      end
    end
  end
end

🚨 Directory traversal in Rack::Directory app bundled with Rack

There was a possible directory traversal vulnerability in the Rack::Directory app
that is bundled with Rack.

Versions Affected: rack < 2.2.0
Not affected: Applications that do not use Rack::Directory.
Fixed Versions: 2.1.3, >= 2.2.0

Impact

If certain directories exist in a director that is managed by
Rack::Directory, an attacker could, using this vulnerability, read the
contents of files on the server that were outside of the root specified in the
Rack::Directory initializer.

Workarounds

Until such time as the patch is applied or their Rack version is upgraded,
we recommend that developers do not use Rack::Directory in their
applications.

🚨 Directory traversal in Rack::Directory app bundled with Rack

There was a possible directory traversal vulnerability in the Rack::Directory app
that is bundled with Rack.

Versions Affected: rack < 2.2.0
Not affected: Applications that do not use Rack::Directory.
Fixed Versions: 2.1.3, >= 2.2.0

Impact

If certain directories exist in a director that is managed by
Rack::Directory, an attacker could, using this vulnerability, read the
contents of files on the server that were outside of the root specified in the
Rack::Directory initializer.

Workarounds

Until such time as the patch is applied or their Rack version is upgraded,
we recommend that developers do not use Rack::Directory in their
applications.

🚨 Possible information leak / session hijack vulnerability

There's a possible information leak / session hijack vulnerability in Rack.

Attackers may be able to find and hijack sessions by using timing attacks
targeting the session id. Session ids are usually stored and indexed in a
database that uses some kind of scheme for speeding up lookups of that
session id. By carefully measuring the amount of time it takes to look up
a session, an attacker may be able to find a valid session id and hijack
the session.

The session id itself may be generated randomly, but the way the session is
indexed by the backing store does not use a secure comparison.

Impact:

The session id stored in a cookie is the same id that is used when querying
the backing session storage engine. Most storage mechanisms (for example a
database) use some sort of indexing in order to speed up the lookup of that
id. By carefully timing requests and session lookup failures, an attacker
may be able to perform a timing attack to determine an existing session id
and hijack that session.

🚨 Possible XSS vulnerability in Rack

There is a possible vulnerability in Rack. This vulnerability has been
assigned the CVE identifier CVE-2018-16471.

Versions Affected: All.
Not affected: None.
Fixed Versions: 2.0.6, 1.6.11

Impact

There is a possible XSS vulnerability in Rack. Carefully crafted requests can
impact the data returned by the scheme method on Rack::Request.
Applications that expect the scheme to be limited to "http" or "https" and do
not escape the return value could be vulnerable to an XSS attack.

Vulnerable code looks something like this:

<%= request.scheme.html_safe %>

Note that applications using the normal escaping mechanisms provided by Rails
may not impacted, but applications that bypass the escaping mechanisms, or do
not use them may be vulnerable.

All users running an affected release should either upgrade or use one of the
workarounds immediately.

Releases

The 2.0.6 and 1.6.11 releases are available at the normal locations.

Workarounds

The following monkey patch can be applied to work around this issue:

require "rack"
require "rack/request"
class Rack::Request

SCHEME_WHITELIST = %w(https http).freeze
def scheme

if get_header(Rack::HTTPS) == 'on'

'https'

elsif get_header(HTTP_X_FORWARDED_SSL) == 'on'

'https'

elsif forwarded_scheme

forwarded_scheme

else

get_header(Rack::RACK_URL_SCHEME)

end

end
def forwarded_scheme

scheme_headers = [

get_header(HTTP_X_FORWARDED_SCHEME),

get_header(HTTP_X_FORWARDED_PROTO).to_s.split(',')[0]

]
scheme_headers.each do |header|

return header if SCHEME_WHITELIST.include?(header)

end
nil

end

end

🚨 Possible DoS vulnerability in Rack

There is a possible DoS vulnerability in the multipart parser in Rack. This
vulnerability has been assigned the CVE identifier CVE-2018-16470.

Versions Affected: 2.0.4, 2.0.5
Not affected: <= 2.0.3
Fixed Versions: 2.0.6

Impact

There is a possible DoS vulnerability in the multipart parser in Rack.
Carefully crafted requests can cause the multipart parser to enter a
pathological state, causing the parser to use CPU resources disproportionate to
the request size.

Impacted code can look something like this:

Rack::Request.new(env).params

But any code that uses the multi-part parser may be vulnerable.

Rack users that have manually adjusted the buffer size in the multipart parser
may be vulnerable as well.

All users running an affected release should either upgrade or use one of the
workarounds immediately.

Releases

The 2.0.6 release is available at the normal locations.

Workarounds

To work around this issue, the following code can be used:

require "rack/multipart/parser"
Rack::Multipart::Parser.send :remove_const, :BUFSIZE

Rack::Multipart::Parser.const_set :BUFSIZE, 16384
