CycloneDX BOM validation fails for git style externalReferences

[valentijnscholten]

Current Behavior

1. Generate a BOM with cyclonedx-npm
2. Observe an externalReference is added containing the git url of the project, i.e. [email protected]:group/repo.git

Steps to Reproduce

1. Upload the generated BOM to DT, or just attached bom-test.json.

When changing the value to [email protected]/repo.git validation passes.

Expected Behavior

Not sure as [email protected]:group/repo.git is not a valid URI so probably also not a valid IRI?

I am still reporting it here to see what/if we can do something and for other that run into the same issue.

It looks like #3831, but really isn't.

ssh://[email protected]:group/repo.git also fails validation.

Maybe cyclonedx shouldn't output invalid URIs/IRIs?

@jkowalleck Do I remember correctly that you did something in cyclonedx-node-npm to fix / re-map SSH URLs?

Do I remember correctly that you did something in cyclonedx-node-npm to fix / re-map SSH URLs?

You rememberer correctly, we do. The CycloneDX schema requires external references to comply to JSON schema 'iri-reference' and XML scheme xs:anyURI. In some package managers it is natively supported to use 'git@.../path' or '....git' as a repo URL.

Even though a [email protected]:group/repo.git might be understood by git, as it has handling for it, this value is still invalid to said schema. Therefore, we transform some well-known repo-hosters' URL to git+ssh://... or git+http://....git or similar. This is done via https://www.npmjs.com/package/hosted-git-info, which known these specific resolutions and endpoints. In general, I's say it would be possible to convert git@<host>:<path> URLs to git+ssh://git@<host>/<path>. But this is just my guts feeling - without any research done.

@jkowalleck Shall I raise an issue on https://github.com/CycloneDX/cyclonedx-node-npm/issues ?

I have the same issue trying to upload an SBOM generated with https://github.com/CycloneDX/cyclonedx-dotnet . When I try to upload to dependency track I get this error. Should I also open an issue there as well?

{
    "status": 400,
    "title": "The uploaded BOM is invalid",
    "detail": "Schema validation failed",
    "errors": [
        "cvc-datatype-valid.1.2.1: '[email protected]:LordVeovis/xmlrpc.git' is not a valid value for 'anyURI'.",
        "cvc-type.3.1.3: The value '[email protected]:LordVeovis/xmlrpc.git' of element 'url' is not valid."
    ]
}

@Recurse-blip , sure. Please report the situation, so tools may be improved.

Is there anything expected from DT here? Can we close this? To my understanding we're merely enforcing the schema, and there's not much we can do about this.

On a related note, #3891 should allow users to disable / enable validation using tags. That way, it's not necessary to globally disable validation, only because a handful ob projects is blocked by invalid BOMs.
