docker scout cves

内容説明	Display CVEs identified in a software artifact
利用方法	`docker scout cves [OPTIONS] [IMAGE\|DIRECTORY\|ARCHIVE]`

内容説明

The docker scout cves command analyzes a software artifact for vulnerabilities.

イメージの指定がない場合は、直近にビルドされた最新のイメージが用いられます。

The following artifact types are supported:

Images
OCI layout directories
Tarball archives, as created by docker save
Local directory or file

By default, the tool expects an image reference, such as:

redis
curlimages/curl:7.87.0
mcr.microsoft.com/dotnet/runtime:7.0

If the artifact you want to analyze is an OCI directory, a tarball archive, a local file or directory, or if you want to control from where the image will be resolved, you must prefix the reference with one of the following:

image:// (default) use a local image, or fall back to a registry lookup
local:// use an image from the local image store (don't do a registry lookup)
registry:// use an image from a registry (don't use a local image)
oci-dir:// use an OCI layout directory
archive:// use a tarball archive, as created by docker save
fs:// use a local directory or file
sbom:// SPDX file or in-toto attestation file with SPDX predicate or syft json SBOM file In case of sbom:// prefix, if the file is not defined then it will try to read it from the standard input.

List all vulnerable packages of a certain type

The following example shows how to generate a list of packages, only including packages of the specified type, and only showing packages that are vulnerable.

$ docker scout cves --format only-packages --only-package-type golang --only-vuln-packages golang:1.18.0
✓ Pulled

Display EPSS score (--epss)

The --epss flag adds Exploit Prediction Scoring System (EPSS) scores to the docker scout cves output. EPSS scores are estimates of the likelihood (probability) that a software vulnerability will be exploited in the wild in the next 30 days. The higher the score, the greater the probability that a vulnerability will be exploited.

$ docker scout cves --epss nginx
 ✓ Provenance obtained from attestation
 ✓ SBOM obtained from attestation, 232 packages indexed
 ✓ Pulled
 ✗ Detected 23 vulnerable packages with a total of 39 vulnerabilities

...

 ✗ HIGH CVE-2023-52425
   https://scout.docker.com/v/CVE-2023-52425
   Affected range  : >=2.5.0-1
   Fixed version   : not fixed
   EPSS Score      : 0.000510
   EPSS Percentile : 0.173680

EPSS Score is a floating point number between 0 and 1 representing the probability of exploitation in the wild in the next 30 days (following score publication).
EPSS Percentile is the percentile of the current score, the proportion of all scored vulnerabilities with the same or a lower EPSS score.

You can use the --epss-score and --epss-percentile flags to filter the output of docker scout cves based on these scores. For example, to only show vulnerabilities with an EPSS score higher than 0.5:

$ docker scout cves --epss --epss-score 0.5 nginx
 ✓ SBOM of image already cached, 232 packages indexed
 ✓ EPSS scores for 2024-03-01 already cached
 ✗ Detected 1 vulnerable package with 1 vulnerability

...

 ✗ LOW CVE-2023-44487
   https://scout.docker.com/v/CVE-2023-44487
   Affected range  : >=1.22.1-9
   Fixed version   : not fixed
   EPSS Score      : 0.705850
   EPSS Percentile : 0.979410

EPSS scores are updated on a daily basis. By default, the latest available score is displayed. You can use the --epss-date flag to manually specify a date in the format yyyy-mm-dd for fetching EPSS scores.

$ docker scout cves --epss --epss-date 2024-01-02 nginx
