Red Hat Security Advisory 2024-3546-03 - An update for the ruby:3.1 module is now available for Red Hat Enterprise Linux 8.

### Impact Users settings their active admin form legends dynamically may be vulnerable to stored XSS, as long as its value can be injected directly by a malicious user. For example: * A public web application allows users to create entities with arbitrary names. * Active Admin is used to administrate these entities through a private backend. * The form to edit these entities in the private backend has the following shape (note the dynamic `name` value dependent on an attribute of the `resource`): ```ruby form do |f| f.inputs name: resource.name do f.input :name f.input :description end f.actions end ``` Then a malicious user could create an entity with a payload that would get executed in the active admin administrator's browser. Both `form` blocks with an implicit or explicit name (i.e., both `form resource.name` or `form name: resource.name` would suffer from the problem), where the value of the name can be arbitrarily set by non admin users. ### ...

Red Hat Security Advisory 2024-3500-03 - An update for the ruby:3.0 module is now available for Red Hat Enterprise Linux 8. Issues addressed include HTTP response splitting and denial of service vulnerabilities.

Red Hat Security Advisory 2024-3431-03 - An update for pcs is now available for Red Hat Enterprise Linux 8.6 Extended Update Support. Issues addressed include a denial of service vulnerability.

### Summary The next ruby code is vulnerable to denial of service due to the fact that the user controlled data `profiler_runs` was not contrained to any limitation. Which would lead to allocating resources on the server side with no limitation (CWE-770). ```ruby runs = (request.params['profiler_runs'] || @times).to_i result = @profile.profile do runs.times { @app.call(env) } end ``` An exploit as such `curl --fail "http://127.0.0.1:9292/?profiler_runs=9999999999&profile=process_time"` may cause resource exhaution by a remotely controlled value. ### PoC Herein the `config.ru` file: ```ruby require 'rack' require 'rack/contrib' use Rack::Profiler # if ENV['RACK_ENV'] == 'development' # Define a Rack application app = lambda do |env| # Your application logic goes here [200, {}, ["Hello World"]] end # Run the Rack application run app ``` A Dockerfile: ```Dockerfile # Use the official Ruby image as a base FROM ruby:latest # Set the working...

A moderate severity security vulnerability has been identified in the Kaminari pagination library for Ruby on Rails, concerning insecure file permissions. This advisory outlines the vulnerability, affected versions, and provides guidance for mitigation. ### Impact This vulnerability is of moderate severity due to the potential for unauthorized write access to particular Ruby files managed by the library. Such access could lead to the alteration of application behavior or data integrity issues. ### Resolution Those who use the `gem install` command, such as `gem install kaminari -v 0.16.1`, `gem unpack kaminari -v 0.16.1`, or `bundle install` to download the package would **_not_** be affected and no action is required. Those who manually download and decompressing the affected versions are advised to update to 0.16.2 or later version of Kaminari where file permissions have been adjusted to enhance security. ### Workarounds If upgrading is not feasible immediately, manually adju...
