Hi there Ruby developers! If you’ve been looking for an effective way to establish a Ruby on Rails Docker setup for your local development environment, then this post is for you. It’s a continuation of our previous article on how to install Ruby in a macOS for local development. Ruby developers frequently need to account for a database when building a Ruby on Rails project, as well as other development environment prerequisites.

Rest-client is one of the most popular RubyGems, with a simple DSL that allows sending HTTP requests. Lightweight, versatile, developed by famous Rubyists…with all these attributes, this gem is a very shiny and attractive target for malicious actors. All they need is a good method of attack. An attempt made today tried to leverage typosquatting by adding malicious code to rest_client, but it didn’t quite ace the assignment.

Snyk Code supports various languages important in the cloud native arena, Ruby being among them (and we’ve seen great adoption, so thank you!). Our researchers are constantly monitoring our rule sets, using our training set of open source projects, but also — and, yes this is an advantage of a SaaS service — how the rules do on the code that is scanned. Just as a reminder, Snyk does not use your code to train our sets — but we do aggregate usage statistics.

In this post, we’ll look at the security blindspots of lockfile injection that a Ruby gem might expose via its Gemfile.lock. As a prelude to that, we will open up with a brief introduction to Ruby and third-party dependencies management around RubyGems and Bundler. Web developers often work on Ruby projects, but are mostly referring to them as the popular open source web application framework Ruby on Rails.

Secure your apps! Protect sensitive data! Easy to say, harder to find solid answers on all the bits and pieces you need to adjust to make sure that happens. That's why we've put together this list of practical advice for securing your Ruby on Rails applications. Whether you're a Rails developer or work on any stack that relies on cloud technologies, we think you'll find something that stands out.

Ruby, much like other programming languages, has an entire ecosystem of third-party open source libraries which it refers to as gems, or sometimes Ruby gems. These gems are authored by the community, and are available from RubyGems.org which is the official registry for Ruby libraries. Similarly to other open source ecosystems, threat actors may publish deliberate malicious code or such which includes backdoors or credentials harvesting.

It’s been a bad month for RubyGems vulnerabilities. Critical CVE-2022-29176 was issued May 8, 2022, and another critical CVE-2022-29218 was discovered less than a week later, on May 11. This new vulnerability would allow for a takeover of new versions of some platform-specific gems under certain circumstances.

On May 6, 2022, a critical CVE was published for RubyGems, the primary packages source for the Ruby ecosystem. This vulnerability created a window of opportunity for malicious actors to take over gems that met the following criteria: Because RubyGems provides data dumps that include a lot of information, it is unfortunately relatively simple to create an automated mining process for these criteria.

The notorious Log4Shell vulnerability CVE-2021-45046, has put Log4j in the spotlight, and grabbed the entire Java community’s attention over the last couple of weeks. Maintainers of Java projects that use Log4j have most probably addressed the issue. Meanwhile, non-java developers are enjoying relative peace of mind, knowing that they are unaffected by one of the major vulnerabilities found in recent years. Unfortunately, this is an incorrect assumption.

Ruby is a well-defined and thought-out language and has been around since the mid-1990s. In 2004, Ruby incorporated RubyGems as its package manager. RubyGems is used to manage libraries and dependencies in a self-contained format known as a gem. The interface for RubyGems is a command line tool that integrates with the Ruby runtime and allows Gemfiles to be added or updated in a project. I looked at three Ruby platforms and found vulnerabilities that were surprising, even to me.
