- Summary
- Connecting to a malicious Codespaces via GH CLI could allow command execution on the user's computer
- Details
-
The GitHub CLI version 2.6.1 and earlier are vulnerable to remote code execution through a malicious codespace SSH server when using
gh codespace sshorgh codespace logscommands. This has been patched in the cli v2.62.0.Developers connect to remote codespaces through an SSH server running within the devcontainer, which is generally provided through the default devcontainer image . GitHub CLI retrieves SSH connection details, such as remote username, which is used in executing <code>ssh</code> commands for
gh codespace sshorgh codespace logscommands.This exploit occurs when a malicious third-party devcontainer contains a modified SSH server that injects
ssharguments within the SSH connection details.gh codespace sshandgh codespace logscommands could execute arbitrary code on the user's workstation if the remote username contains something like-oProxyCommand="echo hacked" #. The-oProxyCommandflag causessshto execute the provided command while#shell comment causes any otherssharguments to be ignored.In
2.62.0, the remote username information is being validated before being used. - Database specific
