[Security] Bump actionpack from 4.2.10 to 6.1.3.2

[dependabot-preview]

Bumps actionpack from 4.2.10 to 6.1.3.2. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Ability to forge per-form CSRF tokens given a global CSRF token It is possible to possible to, given a global CSRF token such as the one present in the authenticity_token meta tag, forge a per-form CSRF token for any action for that session.

Versions Affected: rails < 5.2.5, rails < 6.0.4 Not affected: Applications without existing HTML injection vulnerabilities. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1

Impact

Given the ability to extract the global CSRF token, an attacker would be able to construct a per-form CSRF token for that session.

Workarounds

This is a low-severity security issue. As such, no workaround is necessarily until such time as the application can be upgraded.

Patched versions: ~> 5.2.4.3; >= 6.0.3.1 Unaffected versions: none

Sourced from The Ruby Advisory Database.

Possible Strong Parameters Bypass in ActionPack There is a strong parameters bypass vector in ActionPack.

Versions Affected: rails <= 6.0.3 Not affected: rails < 4.0.0 Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1

Impact

In some cases user supplied information can be inadvertently leaked from Strong Parameters. Specifically the return value of each, or each_value, or each_pair will return the underlying "untrusted" hash of data that was read from the parameters. Applications that use this return value may be inadvertently use untrusted user input.

Impacted code will look something like this:

def update
  # Attacker has included the parameter: `{ is_admin: true }`
  User.update(clean_up_params)
</tr></table> 

... (truncated)

Patched versions: ~> 5.2.4.3; >= 6.0.3.1 Unaffected versions: < 4.0.0

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

... (truncated)

Affected versions: >= 2.0.0, <= 5.2.4.5

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.

Releases

The FIXED releases are available at the normal locations.

Possible DoS Vulnerability in Action Controller Token Authentication There is a possible DoS vulnerability in the Token Authentication logic in Action Controller. This vulnerability has been assigned the CVE identifier CVE-2021-22904.

Versions Affected: >= 4.0.0 Not affected: < 4.0.0 Fixed Versions: 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6

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
