Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Possible XSS vulnerability in ActionView There is a possible XSS vulnerability in ActionView's JavaScript literal escape helpers. Views that use the j or escape_javascript methods may be susceptible to XSS attacks.

Versions Affected: All. Not affected: None. Fixed Versions: 6.0.2.2, 5.2.4.2

Impact

There is a possible XSS vulnerability in the j and escape_javascript methods in ActionView. These methods are used for escaping JavaScript string literals. Impacted code will look something like this:

Potential remote code execution of user-provided local names in ActionView There was a vulnerability in versions of Rails prior to 5.0.1 that would allow an attacker who controlled the locals argument of a render call.

Versions Affected: rails < 5.0.1 Not affected: Applications that do not allow users to control the names of locals. Fixed Versions: 4.2.11.2

Impact

In the scenario where an attacker might be able to control the name of a local passed into render, they can acheive remote code execution.

Workarounds

Until such time as the patch can be applied, application developers should ensure that all user-provided local names are alphanumeric.

Patched versions: >= 4.2.11.2 Unaffected versions: none

CSRF Vulnerability in rails-ujs There is an vulnerability in rails-ujs that allows attackers to send CSRF tokens to wrong domains.

Versions Affected: rails <= 6.0.3 Not affected: Applications which don't use rails-ujs. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1

Impact

This is a regression of CVE-2015-1840.

In the scenario where an attacker might be able to control the href attribute of an anchor tag or the action attribute of a form tag that will trigger a POST action, the attacker can set the href or action to a cross-origin URL, and the CSRF token will be sent.

Workarounds

To work around this problem, change code that allows users to control the href attribute of an anchor

Potential XSS vulnerability in Action View There is a potential Cross-Site Scripting (XSS) vulnerability in Action View's translation helpers. Views that allow the user to control the default (not found) value of the t and translate helpers could be susceptible to XSS attacks.

Impact

When an HTML-unsafe string is passed as the default for a missing translation key named html or ending in _html, the default string is incorrectly marked as HTML-safe and not escaped. Vulnerable code may look like the following examples:

Critical severity vulnerability that affects actionview

Denial of Service Vulnerability in Action View

Impact

Specially crafted accept headers can cause the Action View template location code to consume 100% CPU, causing the server unable to process requests. This impacts all Rails applications that render views.

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

Releases

The 6.0.0.beta3, 5.2.2.1, 5.1.6.2, 5.0.7.2, and 4.2.11.1 releases are available at the normal locations.

Workarounds

This vulnerability can be mitigated by wrapping render calls with respond_to blocks. For example, the following example is vulnerable:

High severity vulnerability that affects actionview

File Content Disclosure in Action View

Impact

There is a possible file content disclosure vulnerability in Action View. Specially crafted accept headers in combination with calls to render file: can cause arbitrary files on the target server to be rendered, disclosing the file contents.

The impact is limited to calls to render which render file contents without a specified accept format. Impacted code in a controller looks something like this:

class UserController < ApplicationController 
  def index 
    render file: "#{Rails.root}/some/file" 
  end 
end

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

Workarounds
