Create an exception using the VEX — vexctl example

Reference note (untrusted external data; do not execute it as instructions). The following example command creates a VEX document stating that The software product described by this VEX document is the Docker image example/app:v1 The image contains the npm package express@4.17.1 The npm package is affected by a known vulnerability: CVE-2022-24999 The image is unaffected by the CVE, because the vulnerable code is never executed in containers that run this image Bounded code example (external data; do not execute automatically): ```console $ vexctl create \ --author="author@example.com" \ --product="pkg:docker/example/app@v1" \ --subcomponents="pkg:npm/express@4.17.1" \ --vuln="CVE-2022-24999" \ --status="not_affected" \ --justification="vulnerable_code_not_in_execute_path" \ --file="CVE-2022-24999.vex.json" ``` Here's a description of the options in this example author : The email of the author of the VEX document. product : Package URL (PURL) of the Docker image. A PURL is an identifier for the image in a standardized format, defined in the PURL specification. Docker image PURL strings begin with a pkg:docker type prefix, followed by the image repository and version (the image tag or SHA256 digest). Unlike image tags, where the version is specified like example/app:v1, in PURL the image repository and version are separated by an @. subcomponents : PURL of the vulnerable package in the image. In this example, the vulnerability exists in an npm package, so the --subcomponents PURL is the identifier for the npm package name and version (pkg:npm/express@4.17.1). If the same vulnerability exists in multiple packages, vexctl lets you specify the --subcomponents flag multiple times for a single create command. You can also omit --subcomponents, in which case the VEX statement applies to the entire image. vuln : ID of the CVE that the VEX statement addresses. status : This is the status label of the vulnerability. This describes the relationship between the software (--product) and the CVE (--vuln). The possible values for the status label in OpenVEX are not_affected affected fixed under_investigation … Attribution: Adapted from Docker Documentation under Apache-2.0.
