# Possible XSS Vulnerability in Rails::Html::SanitizerThere is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer.This vulnerability has been assigned the CVE identifier CVE-2022-32209.Versions Affected: ALLNot affected: NONEFixed Versions: v1.4.3## ImpactA 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. This may be done via application configuration:```ruby# In config/application.rbconfig.action_view.sanitized_allowed_tags = ["select", "style"]```see https://guides.rubyonrails.org/configuring.html#configuring-action-viewOr it may be done with a `:tags` option to the Action View helper `sanitize`:```<%= sanitize @comment.body, tags: ["select", "style"] %>```see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitizeOr it may be done with Rails::Html::SafeListSanitizer directly:```ruby# class-level optionRails::Html::SafeListSanitizer.allowed_tags = ["select", "style"]```or```ruby# instance-level optionRails::Html::SafeListSanitizer.new.sanitize(@article.body, tags: ["select", "style"])```All users overriding the allowed tags by any of the above mechanisms to include both "select" and "style" should either upgrade or use one of the workarounds immediately.## ReleasesThe FIXED releases are available at the normal locations.## WorkaroundsRemove either `select` or `style` from the overridden allowed tags.## CreditsThis vulnerability was responsibly reported by [windshock](https://hackerone.com/windshock?type=user).

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:8506 advisory.

  - The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed     output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are     affected. The malicious input can trigger an OOME and so a DoS attack (CVE-2021-37136)

  - The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory     usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which     may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious     input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable     chunk. (CVE-2021-37137)

  - The {% debug %} template tag in Django 2.2 before 2.2.27, 3.2 before 3.2.12, and 4.0 before 4.0.2 does not     properly encode the current context. This may lead to XSS. (CVE-2022-22818)

  - Nokogiri is an open source XML and HTML library for Ruby. Nokogiri `< v1.13.4` contains an inefficient     regular expression that is susceptible to excessive backtracking when attempting to detect encoding in     HTML documents. Users are advised to upgrade to Nokogiri `>= 1.13.4`. There are no known workarounds for     this issue. (CVE-2022-24836)

  - The package git before 1.11.0 are vulnerable to Command Injection via git argument injection. When calling     the fetch(remote = 'origin', opts = {}) function, the remote parameter is passed to the git fetch     subcommand in a way that additional flags can be set. The additional flags can be used to perform a     command injection. (CVE-2022-25648)

  - Sinatra before 2.2.0 does not validate that the expanded path matches public_dir when serving static     files. (CVE-2022-29970)

(CVE-2022-32209)

  - An issue was discovered in Django 3.2 before 3.2.14 and 4.0 before 4.0.6. The Trunc() and Extract()     database functions are subject to SQL injection if untrusted data is used as a kind/lookup_name value.
    Applications that constrain the lookup name and kind choice to a known safe list are unaffected.

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3566 advisory.

  - rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. 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. This issue has been patched in version 1.4.4. (CVE-2022-23517)

  - rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Versions >=     1.0.3, < 1.4.4 are vulnerable to cross-site scripting via data URIs when used in combination with Loofah     >= 2.1.0. This issue is patched in version 1.4.4. (CVE-2022-23518)

  - rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Prior to version     1.4.4, 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. . This issue is fixed in version     1.4.4. All users overriding the allowed tags to include math or svg and style should either upgrade     or use the following workaround immediately: Remove style from the overridden allowed tags, or remove     math and svg from the overridden allowed tags. (CVE-2022-23519)

  - rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Prior to version     1.4.4, there is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer due to     an incomplete fix of CVE-2022-32209. 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. This issue is patched in version     1.4.4. All users overriding the allowed tags to include both select and style should either upgrade or     use this workaround: Remove either select or style from the overridden allowed tags. NOTE: Code is
    _not_ impacted if allowed tags are overridden using either the :tags option to the Action View helper     method sanitize or the :tags option to the instance method SafeListSanitizer#sanitize. (CVE-2022-23520)
