VCID-782b-usu3-bbhd Aliases: CVE-2022-23519 GHSA-9h9g-93gc-623h GMS-2022-8299	Possible XSS vulnerability with certain configurations of rails-html-sanitizer ## 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: ```ruby # 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 @comment.body, tags: ["math", "style"] %> <%# or %> <%= sanitize @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=`: ```ruby # 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`: ```ruby # 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. ## References - [CWE - CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (4.9)](https://cwe.mitre.org/data/definitions/79.html) - https://hackerone.com/reports/1656627 ## Credit This vulnerability was responsibly reported by Dominic Breuker.	There are no reported fixed by versions.
VCID-wxfr-bs81-augc Aliases: CVE-2022-23518 GHSA-mcvf-2q2m-x72m GMS-2022-8300	Improper neutralization of data URIs may allow XSS in rails-html-sanitizer ## Summary rails-html-sanitizer `>= 1.0.3, < 1.4.4` is vulnerable to cross-site scripting via data URIs when used in combination with Loofah `>= 2.1.0`. ## Mitigation Upgrade to rails-html-sanitizer `>= 1.4.4`. ## Severity The maintainers have evaluated this as [Medium Severity 6.1](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N). ## References - [CWE - CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (4.9)](https://cwe.mitre.org/data/definitions/79.html) - [SVG MIME Type (image/svg+xml) is misleading to developers · Issue #266 · w3c/svgwg](https://github.com/w3c/svgwg/issues/266) - https://github.com/rails/rails-html-sanitizer/issues/135 - https://hackerone.com/reports/1694173 ## Credit This vulnerability was independently reported by Maciej Piechota (@haqpl) and Mrinmoy Das (@goromlagche).	There are no reported fixed by versions.
VCID-zcs7-hzze-u3a5 Aliases: CVE-2022-23520 GHSA-rrfc-7g8p-99q8 GMS-2022-8301	Possible XSS vulnerability with certain configurations of rails-html-sanitizer ## 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=`: ```ruby # 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=`: ```ruby # 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. ## References - [CWE - CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (4.9)](https://cwe.mitre.org/data/definitions/79.html) - https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-32209 - https://hackerone.com/reports/1654310 ## Credit This vulnerability was responsibly reported by Dominic Breuker.
