[dependabot-preview]

Bumps actionpack from 6.0.3.4 to 6.0.3.7. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Possible Open Redirect in Host Authorization Middleware There is a possible open redirect vulnerability in the Host Authorization middleware in Action Pack. This vulnerability has been assigned the CVE identifier CVE-2021-22881.

Versions Affected: >= 6.0.0 Not affected: < 6.0.0 Fixed Versions: 6.1.2.1, 6.0.3.5

Impact

Specially crafted "Host" headers in combination with certain "allowed host" formats can cause the Host Authorization middleware in Action Pack to redirect users to a malicious website.

Impacted applications will have allowed hosts with a leading dot. For example, configuration files that look like this:

config.hosts <<  '.tkte.ch'

Patched versions: ~> 6.0.3.5; >= 6.1.2.1 Unaffected versions: < 6.0.0

Sourced from The GitHub Security Advisory Database.

Denial of Service in Action Dispatch Impact

There is a possible Denial of Service vulnerability in Action Dispatch. Carefully crafted Accept headers can cause the mime type parser in Action Dispatch to do catastrophic backtracking in the regular expression engine.

Releases

The fixed releases are available at the normal locations.

Workarounds

The following monkey patch placed in an initializer can be used to work around the issue.

module Mime
  class Type
    MIME_REGEXP = /\A(?:\*\/\*|#{MIME_NAME}\/(?:\*|#{MIME_NAME})(?>\s*#{MIME_PARAMETER}\s*)*)\z/
  end
</tr></table>

Affected versions: >= 6.0.0, <= 6.0.3.6

Sourced from The GitHub Security Advisory Database.

Denial of Service in Action Controller Token Authentication Impact

Impacted code uses authenticate_or_request_with_http_token or authenticate_with_http_token for request authentication. Impacted code will look something like this:

class PostsController < ApplicationController
  before_action :authenticate
private
def authenticate
authenticate_or_request_with_http_token do |token, options|
# ...
end
end
end

Affected versions: >= 6.0.0, <= 6.0.3.6

Sourced from The GitHub Security Advisory Database.

Information Disclosure / Unintended Method Execution in Action Pack Impact

There is a possible information disclosure / unintended method execution vulnerability in Action Pack when using the redirect_to or polymorphic_url helper with untrusted user input.

Vulnerable code will look like this.

redirect_to(params[:some_param])

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

Action Pack

• Prevent catastrophic backtracking during mime parsing CVE-2021-22902

• Prevent regex DoS in HTTP token authentication CVE-2021-22904

• Prevent string polymorphic route arguments.

  url_for supports building polymorphic URLs via an array of arguments (usually symbols and records). If a developer passes a user input array, strings can result in unwanted route helper calls.
