CVE-2022-23520

Summary

There is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer. This is due to an incomplete fix of CVE-2022-32209.

• Versions affected: ALL
• Not affected: NONE
• Fixed versions: 1.4.4

Impact

A possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags to allow both "select" and "style" elements.

Code is only impacted if allowed tags are being overridden using either of the following two mechanisms:

1. Using the Rails configuration config.action_view.sanitized_allow_tags=:

# In config/application.rb
config.action_view.sanitized_allowed_tags = ["select", "style"]

(see https://guides.rubyonrails.org/configuring.html#configuring-action-view)

2. Using the class method Rails::Html::SafeListSanitizer.allowed_tags=:

# class-level option
Rails::Html::SafeListSanitizer.allowed_tags = ["select", "style"]

All users overriding the allowed tags by either of the above mechanisms to include both "select" and "style" should either upgrade or use one of the workarounds immediately.

NOTE: Code is not impacted if allowed tags are overridden using either of the following mechanisms:

• the :tags option to the Action View helper method sanitize.
• the :tags option to the instance method SafeListSanitizer#sanitize.

Workarounds

Remove either "select" or "style" from the overridden allowed tags.

CVE-2022-23519

Summary

There is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer.

• Versions affected: ALL
• Not affected: NONE
• Fixed versions: 1.4.4

Impact

A possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags in either of the following ways:

• allow both "math" and "style" elements,
• or allow both "svg" and "style" elements

Code is only impacted if allowed tags are being overridden. Applications may be doing this in four different ways:

1. using application configuration:

# In config/application.rb
config.action_view.sanitized_allowed_tags = ["math", "style"]
# or
config.action_view.sanitized_allowed_tags = ["svg", "style"]

see https://guides.rubyonrails.org/configuring.html#configuring-action-view

2. using a :tags option to the Action View helper sanitize:

<%= sanitize @&#8203;comment.body, tags: ["math", "style"] %>
<%# or %>
<%= sanitize @&#8203;comment.body, tags: ["svg", "style"] %>

see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitize

3. using Rails::Html::SafeListSanitizer class method allowed_tags=:

# class-level option
Rails::Html::SafeListSanitizer.allowed_tags = ["math", "style"]
# or
Rails::Html::SafeListSanitizer.allowed_tags = ["svg", "style"]

4. using a :tags options to the Rails::Html::SafeListSanitizer instance method sanitize:

# instance-level option
Rails::Html::SafeListSanitizer.new.sanitize(@​article.body, tags: ["math", "style"])
# or
Rails::Html::SafeListSanitizer.new.sanitize(@​article.body, tags: ["svg", "style"])

All users overriding the allowed tags by any of the above mechanisms to include (("math" or "svg") and "style") should either upgrade or use one of the workarounds immediately.

Workarounds

Remove "style" from the overridden allowed tags, or remove "math" and "svg" from the overridden allowed tags.

CVE-2022-23517

Summary

Certain configurations of rails-html-sanitizer < 1.4.4 use an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption.

Mitigation

Upgrade to rails-html-sanitizer >= 1.4.4.

Severity

The maintainers have evaluated this as High Severity 7.5 (CVSS3.1).
