![]() If you need help, other developers can pull your branch and have the latest version of your code.Having your own branch brings many benefits: Before making any code change, start a new Git branch where all your changes will be made. The first good hygiene rule for making a code review/pull request is to commit all your changes in your own branch. Create a new Git branch for your code review While the wording is different, the intent is the same: a developer has some changes they want to merge into the main branch. On GitLab, this is called a Merge Request (MR). On GitHub or Bitbucket, a developer opens a Pull Request (PR) to make a code review. When using Git, code review is a synonym for Pull Request. During the code reviews, tests are executed to check if there is any regression in the new code and teammates are checking the code to verify if there is anything wrong and if requirements are correctly implemented. What is a Code Review?Ī code review is a process of sending code changes to be reviewed and tested. Check what is the default name branch in your repository configuration. Important note: due to some changes months ago in version control platforms, the default main branch may be called master or main. ![]() There are many different ways you can manage your git projects, but this blog will focus on some tips to help you use Git more efficiently when performing code reviews with your team. They help programmers keep track of their projects and ensure that the changes they make are not lost. ![]() They have to implement a simple interface with a method named handleUri() and announce it to the IDE with window.Git and other source code management tools have become a staple in software development and coding. The main listener will handle such OS-level events and redirect them to the right extension. The IDE allows internal and external extensions to listen to such events and handle them by registering sub-handlers. In the case of Visual Studio Code, vscode:// is registered, and vscode-insiders:// for the nightly builds (also called Insiders build). This choice still allows some level of integration with the user's operating system, for instance, by allowing applications to register custom URL protocol handlers. Visual Studio Code is most commonly used as a stand-alone desktop application, thanks to Electron. Further sections will describe how it could be exploited to gain the ability to execute arbitrary commands, as well as the patch implemented by Microsoft. In the sections below, we'll first describe how URL handlers are designed in Visual Studio Code and then review the implementation of the one reserved for Git actions to identify an argument injection bug. For instance, this is how GitLab allows easier cloning of projects:ĭemonstration of the successful exploitation of the vulnerability on a macOS host by starting the macOS Calculator application This operation is genuine and part of the workflow of most users. Upon clicking on a malicious link crafted by an attacker, victims are prompted to clone a Git repository in Visual Studio Code. The vulnerability can be used to target developers that have the Visual Studio Code IDE installed. By reporting the issue to Microsoft, who quickly patched it, our researchers helped to secure the developer ecosystem. It allowed attackers to craft malicious links that, once interacted with, would trick the IDE into executing unintended commands on the victim's computer. This time, we dive into a new vulnerability we identified in one of the most popular IDEs: Visual Studio Code. ![]() Welcome back to our Securing Developer Tools series ( part 1, part 2), in which we look at the security of software used by millions of developers every day! The safety of these applications is crucial to prevent attackers from compromising the computer on which developers are working, as they could use this access to obtain sensitive information, alter source code, and further pivot into the company's internal network.
