The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 ssh` or `gh codespace logs` commands. 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](     https://docs.github.com/en/codespaces/setting-up-your-project-for-codespaces/adding-a-dev-container-...

GitHub CLI     [retrieves SSH connection details](     https://github.com/cli/cli/blob/30066b0042d0c5928d959e288144300cb28196c9/internal/codespaces/rpc/inv... ht     tps://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...

This 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. In `2.62.0`, the remote username information is being validated     before being used. (CVE-2024-52308)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 24.04 LTS / 24.10 host has a package installed that is affected by a vulnerability as referenced in the USN-7130-1 advisory.

    It was discovered that GitHub CLI incorrectly handled username validation. An attacker could possibly use     this issue to perform

    remote code execution if the user connected to a malicious server. (CVE-2024-52308)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of gh installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-52308 advisory.
