Run a vulnerability scan

You can scan vulnerabilities by running the appropriate commands. The CLI provides flexibility and automation capabilities for integrating vulnerability scanning into your existing workflows or CI/CD pipelines. The tool allows scanning an image, directory, file, or a previously generated SBOM.

Usage:

kubeclarity-cli scan <image/sbom/directory/file name> --input-type <sbom|dir|file|image(default)> -f <output file>

Example:

kubeclarity-cli scan nginx.sbom --input-type sbom

You can list the vulnerability scanners to use using the SCANNERS_LIST environment variable separated by a space (SCANNERS_LIST="<Scanner1 name> <Scanner2 name>"). For example:

SCANNERS_LIST="grype trivy" kubeclarity-cli scan nginx.sbom --input-type sbom

Example output:

Export results to KubeClarity backend

To export the CLI results to the KubeClarity backend, complete the following steps.

To export CLI-generated results to the backend, from the left menu bar select Applications, then copy the ID from the KubeClarity UI. If your application is not listed yet, select + New Application, and create a new pod.

To export the vulnerability scan results to the KubeClarity backend, set the BACKEND_HOST environment variable and the -e flag.

Note: Until TLS is supported, set BACKEND_DISABLE_TLS=true.

BACKEND_HOST=<KubeClarity backend address> BACKEND_DISABLE_TLS=true kubeclarity-cli scan <image> --application-id <application ID> -e

For example:

SCANNERS_LIST="grype" BACKEND_HOST=localhost:9999 BACKEND_DISABLE_TLS=true kubeclarity-cli scan nginx.sbom --input-type sbom  --application-id 23452f9c-6e31-5845-bf53-6566b81a2906 -e

Now you can see the exported results on the UI.

Check scan results on the UI

To see the results of a vulnerability scan, select the Vulnerabilities page in KubeClarity UI. It shows a report including the vulnerability names, severity, the package of origin, available fixes, and attribution to the scanner that reported the vulnerability.
You can click on any of these fields to access more in-depth information. For example, click on the name of a vulnerability in the VULNERABILITY NAME column.
Select CVSS to show the CVSS scores and other details reported from the scanning process.
Navigate back to the Vulnerabilities view to explore the filtering options. Filtering helps you reduce noise and improve efficiency in identifying and potentially fixing crucial vulnerabilities.
The KubeClarity Dashboard gives you insights into vulnerability trends and fixable vulnerabilities.
