Viewing Security Vulnerabilities
Introduction
The image vulnerabilities command can be used to return a list of vulnerabilities found in the container image.
# anchorectl image vulnerabilities INPUT_IMAGE -t VULN_TYPE
The INPUT_IMAGE can be specified in one of the following formats:
- Image Digest
- Image ID
- registry/repo:tag
The VULN_TYPE currently supports:
- os: Vulnerabilities against operating system packages (RPM, DPKG, APK, etc.)
- non-os: Vulnerabilities against language packages (NPM, GEM, Java Archive (jar, war, ear), Python PIP, .NET NuGet, etc.)
- all: Combination report containing both ‘os’ and ’non-os’ vulnerability records.
The system has been designed to incorporate 3rd party feeds for other vulnerabilites.
Examples
To generate a report of OS package (RPM/DEB/APK) vulnerabilities found in the image including CVE identifier, Vulnerable Package, Severity Level, Vulnerability details and version of fixed package (if available).
# anchorectl image vulnerabilities debian:latest -t os
Currently the following the system draws vulnerability data specifically matched to the following OS distros:
- Alpine
- CentOS
- Debian
- Oracle Linux
- Red Hat Enterprise Linux
- Red Hat Universal Base Image (UBI)
- Ubuntu
- Suse Linux
- Amazon Linux 2
- Google Distroless
To generate a report of language package (NPM/GEM/Java/Python) vulnerabilities, the system draws vulnerability data from the NVD data feed, and vulnerability reports can be viewed using the ’non-os’ vulnerability type:
# anchorectl image vulnerabilities node:latest -t non-os
To generate a list of all vulnerabilities that can be found, regardless of whether they are against an OS or non-OS package type, the ‘all’ vulnerability type can be used:
# anchorectl image vulnerabilities node:latest -t all
Finally, for any of the above queries, these commands (and other anchorectl commands) can be passed the -o json flag to output the data in JSON format:
# anchorectl -o json image vulnerabilities node:latest -t all
Other options can be reviewed by issuing anchorectl image vulnerabilities --help at any time.
Next Steps
- Evaluate the image against policies you create.
- Subscribe to receive notifications when the image is updated, when the policy status changes or when new vulnerabilities are detected.
