[Security] Bump actionpack from 5.2.3 to 6.0.3.4

[dependabot-preview[bot]]

Bumps actionpack from 5.2.3 to 6.0.3.4. 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

Changelog

Sourced from actionpack's changelog.

Rails 6.0.3.4 (October 07, 2020)

• [CVE-2020-8264] Prevent XSS in Actionable Exceptions

Rails 6.0.3.3 (September 09, 2020)

• No changes.

Rails 6.0.3.2 (June 17, 2020)

Rails 6.0.3.1 (May 18, 2020)

• [CVE-2020-8166] HMAC raw CSRF token before masking it, so it cannot be used to reconstruct a per-form token

• [CVE-2020-8164] Return self when calling #each, #each_pair, and #each_value instead of the raw @parameters hash

Rails 6.0.3 (May 06, 2020)

• Include child session assertion count in ActionDispatch::IntegrationTest

  IntegrationTest#open_session uses dup to create the new session, which meant it had its own copy of @assertions. This prevented the assertions from being correctly counted and reported.

  Child sessions now have their attr_accessor overriden to delegate to the root session.

  Fixes #32142
