Configure SSHD service to permit login without password. - #804

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe change removes SSH key handling from the Dev Spaces connection page and gateway URI. Manual SSH instructions no longer include key setup or identity-file guidance. The SSH startup script enables empty-password login and stops creating client keys. It also removes existing image, validation, release, rebase, smoke-test, and web-IDE workflows, and adds a manual SSH daemon image publishing workflow. Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~45 minutes Change: Feature Merge Risk: 🟠 High · up to The keyless connection flow is currently incompatible with the companion extension, and the replacement image-publishing workflow cannot reliably start. Resolve these failures and the passwd-account matching issue before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

💡 Result:
The search found the relevant integration in Eclipse Che/Dev Spaces:
- The URI scheme is
vscode://redhat.devspaces-remote-ssh, handled by the Dev Spaces Local/Remote Support – SSH extension. [1] - The parameters you listed—
key,namespace,podName,userName, anddwName—appear to identify the SSH key plus the target DevWorkspace pod and user namespace. - Eclipse Che’s main repository references the
che-coderepository as the Code OSS fork used by Che. [2]
I couldn’t find an indexed source showing the exact parameter construction in eclipse-che/che-code; GitHub code search may require authentication or indexing has not exposed it.
🌐 Web query:
GitHub redhat devspaces-remote-ssh extension URI key namespace podName userName dwName
💡 Result:
The redhat.devspaces-remote-ssh extension for VS Code-based editors primarily uses URI-based handlers [1][2] or landing page URLs [1][3] to facilitate connections to Red Hat OpenShift Dev Spaces workspaces, rather than requiring users to manually construct URIs with specific namespace, pod, or user parameters. The extension documentation and implementation details indicate the following: 1. URI Handler: The extension supports a vscode:// URI scheme (typically vscode://redhat.devspaces-remote-ssh) [4] that can be triggered from the Dev Spaces landing page [1][2]. This mechanism automates the connection process, removing the need for manual configuration of internal workspace identifiers [2][3]. 2. Workspace Resolution: Internally, the extension discovers and resolves workspace metadata (such as namespaces and pod names) automatically [5][2]. When a user connects via the provided URI or landing page, the extension leverages the cluster context and workspace discovery logic—often using OpenShift CLI (oc) commands or internal APIs—to locate the target DevWorkspace without the user needing to specify a userName, podName, or dwName manually [5][6][3]. 3. Evolution of Workflows: While older workflows relied on providing a full landing page URL (https://${CLUSTER_URL}/${USER}/${DEVWORKSPACE_NAME}/3400/) [1][2], modern versions (starting from Dev Spaces 3.28) emphasize the use of the URI handler triggered directly from the workspace UI to improve usability and integration [1][2]. For troubleshooting or advanced configuration, the extension settings provide limited options (e.g., devspaces.ssh.log) [2], but it is designed to manage the underlying connection parameters, such as namespace and pod targeting, automatically [5][2]. If you are attempting to programmatically invoke the extension, it is recommended to utilize the standard URI scheme provided by the Dev Spaces platform rather than attempting to construct custom query parameters, as the extension's internal resolution logic is subject to change [5][4].

💡 Result:
The terms namespace, podName, userName, and dwName are components often used to identify and interact with developer workspaces in cloud-native environments, particularly within Red Hat OpenShift Dev Spaces [1]. In this context, dwName refers to the DevWorkspace name, which is a custom resource used to define a developer workspace [1]. These identifiers are frequently used in URLs or configuration paths to facilitate connections between local development tools, such as VS Code, and remote development containers running on a cluster [1]. For example, when accessing or connecting to a developer workspace, you might see these identifiers structured within a URL or path, such as: https://${CLUSTER_URL}/${USER}/${DEVWORKSPACE_NAME}/3400/ [1] In this structure: - ${USER} corresponds to the userName. - ${DEVWORKSPACE_NAME} corresponds to the dwName. Namespace and podName are standard Kubernetes concepts often required to locate or manage the underlying infrastructure resources where the developer workspace (dwName) is executing [1].

Keep key in both Dev Spaces Remote SSH URIs or update the extension contract.
If the deployed extension uses handleVSCodeURI, it reads qParams.get("key") and returns when the value is missing. It does not create the SSH key file, port forward, or remote window. Therefore, both keyless URIs can prevent users from connecting. Update the extension and its key acquisition flow before removing key, or continue including it in both URI builders.

Troubleshooting
If the connection fails with "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED", it may be necessary to remove the localhost or 127.0.0.1 entries from $\{HOME\}/.ssh/known_hosts. This is because the SSHD service container (to which oc port-forward is forwarding) may change. This can be bypassed by setting UserKnownHostsFile /dev/null
If the connection fails for an unknown reason, consider disabling the setting remote.SSH.useExecServer (set to false)
For any other issues, relating to the use of a VS Code-based editor and the "Remote - SSH", the "Remote - SSH" logs from the "Output" view are very helpful in diagnosing the issue.

Broken Authentication
Reachability: External
Exploitability: Moderate
CWE: CWE-287 — Improper Authentication
Match the passwd record by its exact UID.
Line 55 matches $USER_ID anywhere in a passwd record. If USER_ID=1, it can modify multiple records. Lines 53–55 can then give an unintended record a login shell and an empty password. With PermitEmptyPasswords yes and password authentication enabled, that record can allow passwordless SSH login through the documented port-forward path.
Use an exact comparison with passwd field 3 for all three rewrites.

Seems like a valid thing to fix. I think I could change this block to search for :$USER_ID: rather than just USER_ID.
There was a problem hiding this comment.
@rgrunber, :$USER_ID: is safer than $USER_ID, but it can still match another colon-delimited field.
Match the UID in passwd field 3 only. For example, use a record selector equivalent to:
/^[^:]*:[^:]*:$USER_ID:/Apply that selector to all three rewrites. This limits the empty-password and login-shell changes to the intended passwd record.

Security Misconfiguration
Reachability: Internal
Exploitability: Difficult
CWE: CWE-732 — Incorrect Permission Assignment for Critical Resource
Restrict the workflow token to read-only contents access.
This workflow checks out repository code and runs a Docker build, but it does not declare permissions. Add a workflow-level permissions: contents: read block so the GITHUB_TOKEN does not inherit broader repository or organization defaults. The Quay login uses separate credentials and needs no additional GitHub permission.

Update the unsupported action versions.
actions/checkout@v2 uses the removed Node 12 runtime. docker/login-action@v2 uses the removed Node 16 runtime. Either step can fail before docker buildx runs. Upgrade both actions to supported major versions.

Broken Authentication
CWE: CWE-287 — Improper Authentication
Match USER_ID against passwd field 3 only.
The /:$USER_ID:/ selector matches any colon-delimited field. If a record has USER_ID as its GID, these rules can change that unrelated account's shell, home, and password field. With empty-password authentication enabled, the wrong account may accept passwordless SSH.
Use a selector such as /^[^:]*:[^:]*:$USER_ID:/. Apply the same field-3 match to the USER_NAME lookup and cleanup. Verify whether the SSH port is reachable only through the intended authenticated port-forward.

Does exactly what it claims. Eliminates the need to configure key authentication, which remains one of the more annoying aspects of the SSHD connection.
I need to test this more thoroughly. Particularly, https://github.com/redhat-developer/devspaces-remote-ssh needs to adapt to no longer expect the SSH key if not present.
