Background
GitHub CLI is a command-line tool that allows developers to interact with GitHub repositories and manage workflows directly from the terminal. It provides functionalities such as creating issues, managing pull requests, and accessing Codespaces. However, its reliance on SSH connections to remote Codespaces makes it susceptible to vulnerabilities, particularly when users connect to untrusted or malicious environments.
Vulnerability Detail
A security vulnerability exists in GitHub CLI that could enable remote code execution (RCE) when users connect to a compromised Codespace SSH server using the 'gh codespace ssh' or 'gh codespace logs' commands. The issue arises from improper handling of SSH connection details, allowing a malicious devcontainer to inject harmful SSH arguments. For instance, if a remote username is crafted to include '-oProxyCommand="echo hacked" #', it can lead to arbitrary command execution on the user's machine. This vulnerability has a CVSS score of 8.0, indicating a high severity level, and could potentially compromise user data and system integrity.
