This has been patched in the cli v2.62.0.\n\nDevelopers connect to remote codespaces through an SSH server running within the devcontainer, which is generally provided through the [default devcontainer image]( https://docs.github.com/en/codespaces/setting-up-your-project-for-codespaces/adding-a-dev-container-... https://docs.github.com/en/codespaces/setting-up-your-project-for-codespaces/adding-a-dev-container-configuration/introduction-to-dev-containers#using-the-default-dev-container-configuration) . GitHub CLI [retrieves SSH connection details]( https://github.com/cli/cli/blob/30066b0042d0c5928d959e288144300cb28196c9/internal/codespaces/rpc/inv... https://github.com/cli/cli/blob/30066b0042d0c5928d959e288144300cb28196c9/internal/codespaces/rpc/invoker.go#L230-L244 ), such as remote username, which is used in [executing `ssh` commands]( https://github.com/cli/cli/blob/e356c69a6f0125cfaac782c35acf77314f18908d/pkg/cmd/codespace/ssh.go#L2... https://github.com/cli/cli/blob/e356c69a6f0125cfaac782c35acf77314f18908d/pkg/cmd/codespace/ssh.go#L263 ) for `gh codespace ssh` or `gh codespace logs` commands.\n\nThis exploit occurs when a malicious third-party devcontainer contains a modified SSH server that injects `ssh` arguments within the SSH connection details. `gh codespace ssh` and `gh codespace logs` commands could execute arbitrary code on the user's workstation if the remote username contains something like `-oProxyCommand=\"echo hacked\" #`. The `-oProxyCommand` flag causes `ssh` to execute the provided command while `#` shell comment causes any other `ssh` arguments to be ignored.\n\nIn `2.62.0`, the remote username information is being validated before being used." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection')", "cweId": "CWE-77" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "cli", "product": { "product_data": [ { "product_name": "cli", "version": { "version_data": [ { "version_affected": "=", "version_value": "<= 2.61.0" } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://github.com/cli/cli/security/advisories/GHSA-p2h2-3vg9-4p87", "refsource": "MISC", "name": "https://github.com/cli/cli/security/advisories/GHSA-p2h2-3vg9-4p87" } ] }, "generator": { "engine": "Vulnogram 0.2.0" }, "source": { "advisory": "GHSA-p2h2-3vg9-4p87", "discovery": "UNKNOWN" }, "credits": [ { "lang": "en", "value": "RyotaK from Flatt Security Inc." } ], "impact": { "cvss": [ { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 8, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "scope": "CHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H", "version": "3.1" } ] } }
