However, despite its popularity, security is still a concern for developers with Docker vulnerabilities out in the wild that can put your product at risk. }, "SimPL-2.0": { "filesystemPolicy": false, Do not embed any secrets in the container image. The open source project runC, which powers the runtime capabilities of nearly all of the container technologies from across the various vendors, was found to have a remote code execution risk due to a container breakout vulnerability that could give the attacker root access to the targeted host. images for vulnerabilities. Introduced through: gcc-defaults/g++@4:8.3.0-1. and 4 more Leading the pack in the container game has been Docker with its trademark blue whale logo that has become synonymous with container technology. remediate the CVEs discovered. The minimum version required for Snyk is 1.385.0. Organization: docker-desktop-test Using minimal, container-centric host systems like CoreOS, Red Hat Atomic, RancherOS, etc, will reduce your attack surface and can bring some helpful new features like running system services in containers as well. For its ability to give an intruder a high level of access, CVE-2018-9862 picked up a 7.8 CVSS v3 rating. For example: You can also display the scan result as a JSON output by adding the --json flag to the command. They could accomplish this by overwriting the hosts runC binary. libidn2/libidn2-0 @ 2.0.5-1+deb10u1 We would strongly suggest double checking with your team that you have patched any of these issues in your own containers, just in case something might have slipped by. Try to replicate the production loads on pre-production. { "issuesData": {}, Sometimes just exposing the file system with read-only privileges should be enough, dont give write access without questioning why. Live-patching containers is usually considered a bad practice, the pattern is to rebuild the entire image with each update. Docker has declarative, efficient, easy to understand build systems, so this is easier than it may sound at first. "docker-image|docker-scan@e2e", } The syntax is docker scan --file PATH_TO_DOCKERFILE DOCKER_IMAGE. Having generous logs and events from your services and hosts, correctly stored and easily searchable and correlated with any change you do will help a lot when you have to do a post-mortem analysis. For information about the system requirements to run vulnerability scanning, see Prerequisites. "message": "Note that we do not currently have vulnerability data for your image. Description: Missing Release of Resource after Effective Lifetime For example: Docker Scan uses the Snyk binary installed in your environment by default. The containment error, with the CVE-2019-5736 has been upgraded from its initial 7.2 CVSS v3 rating to a more appropriate 8.6 High. e2fsprogs/libcom-err2 @ 1.44.5-1+deb10u3 Now, launch a new container using this profile and check that the restriction is enforced: Description: The container breakout term is used to denote that the Docker container has bypassed isolation checks, accessing sensitive information from the host or gaining additional privileges. "bash@5.0-4" It received a High CVSS v3 rating, coming in at 8.6. To run vulnerability scanning on your Docker images, you must meet the following requirements: Download and install the latest version of Docker Desktop. You need an automatic and secure process to share this sensitive info. information about automatically scanning Docker images through Docker Hub, see Do not attempt to create your own secrets storage (curl-ing from a secrets server, mounting volumes, etc, etc) unless you know really really well what you are doing. Package manager: deb Note that we do not currently have vulnerability data for your image. You can enforce Mandatory Access Control to prevent undesired operations -both on the host and on the containers- at the kernel level using tools like Seccomp, AppArmor or SELinux. libunistring/libunistring2 @ 0.9.10-1 krb5/libkrb5support0 @ 1.17-3 For starters, containers are isolated software units which makes it harder for malicious actors to escalate from one vulnerability in a containerized application to another or into the OS itself. }, "summary": "880 vulnerable dependency paths", "instructions": "" "CVSSv3": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:F". Docker security: security monitoring and security tools are becoming hot topics in the modern IT world as the early adoption fever is transforming into a mature ecosystem. This option displays a detailed scan result, Display the result of the scan in JSON format, Log into Snyk using an optional token (using the flag --token), or by using a web-based token, Reject the license agreement of the third-party scanning provider, Only report vulnerabilities of provided level or higher (low, medium, high), Use the authentication token to log into the third-party scanning provider. Alternatively, open a terminal and run the command docker login. User data is clearly separated from the images, making this whole process safer. "projectName": "docker-image|docker-scan", libidn2/libidn2-0 @ 2.0.5-1+deb10u1 According to the reports, this CVE was similar to a 2016 Docker vulnerability in runC, CVE-2016-3697 that also granted root access. "summary": "No known vulnerabilities", Testing docker-scan:e2e Less software means smaller probability of being affected by a vulnerability. In this article we are going to cover 7 fundamental Docker security vulnerabilities and threats. As with everything security, your first steps should be to make sure that your applications are up to date with the latest patched versions. Usually, these special mounts are required to perform the containers core functionality, make sure you understand why and how to limit the processes that can access this privileged information. Sign in to Docker to start scanning your images for vulnerabilities. { Desktop installation to 4.3.1 or higher to fix this issue. Runtime security can be compared to Windows anti-virus scanning: detect and prevent an existing break from further penetration. Containers come with a number of security advantages that give them an edge over your more common operating systems or even virtual machines (VMs). openssl/libssl1.1 @ 1.1.1d-0+deb10u3 The Vulnerability scanning feature doesnt work with Alpine distributions. In any case, Docker does copy-on-write to prevent changes in one running container to affect the base image that might be used for other container. While perhaps not only relevant to Dockers specific products because as open source reliant technology containers share plenty of the same open source projects at their core, these vulnerabilities have caught more than their fair share of attention over the past year or so. "isPatchable": false, Medium severity vulnerability found in sqlite3/libsqlite3-0 Then there are great Docker tools like the Docker Content Trust (DCT) which can come in handy for avoiding those Man-in-the-Middle attacks while you are moving your Docker containers around the network. gnupg2/dirmngr @ 2.2.12-1+deb10u1. Base image: golang:1.14.6 { krb5/libk5crypto3 @ 1.17-3 Use a vulnerability scanner, there are plenty out there, both free and commercial. An input validation CWE that threatened a remote code execution, CVE-2018-8115 hit users of Docker for Windows with a particularly nasty threat back when it was disclosed in February of 2018. "affectedPkgs": {} higher. Docker image: 99138c65ebc7 Try to stay up to date on the security issues of the software you use subscribing to the mailing lists, alert services, etc. This option requires the --file option to be set, Specify the location of the Dockerfile associated with the image. Similar to the Skeleton runtime vulnerability, this CVE is also a Permissions, Privileges, and Access Control issue that due to its extensive potential for havoc, garnered a 9.6 Critical CVSS v3 rating. You may want to restrict this in your containers, specially if you have backend storage mounts with sensitive user data. Testing hello-world Arbitrary Code Execution (new) [Critical Severity][https://snyk.io/vuln/SNYK-JAVA-ORGAPACHELOGGINGLOG4J-2314720] in org.apache.logging.log4j:log4j-core@2.14.0 "packageManager": "debian:10". ] "filesystemPolicy": false, in the output log similar to: For more information, read our blog post Apache Log4j 2 Do you trust the image creator? This excludes the base image (specified in the Dockerfile using the FROM directive) vulnerabilities from your report. openldap/libldap-common @ 2.4.47+dfsg-3+deb10u2 You can set the severity flag to low, medium, or high depending on the level of vulnerabilities youd like to see in your report. ./bin/docker-scan_darwin_amd64 scan --severity=medium docker-scan:e2e The high-level docker scan command scans local images using the image name or the image ID. Organization: docker-desktop-test Docker image: 99138c65ebc7 } We would advise utilizing a limited number of known uids with well-defined roles that. It would seem that 2018 was not a great year for Apache OpenWhisk users, highlighted here in CVE-201811756. On Linux and other systems that support \"saved UID\" functionality, the saved UID is not dropped. Avoid running containers as uid 0, if possible. openssl @ 1.1.1d-0+deb10u3 e2fsprogs/libcom-err2 @ 1.44.5-1+deb10u3 "uniqueCount": 0, Hopefully these simple examples have stirred up your interest in the matter! Docker containers are reproducible: Due to their declarative build systems any admin can easily inspect how the container is built and fully understand every step. CVE-2021-44228 when you scan your This vulnerability highlighted the risk of attacker-controlled images and other situations where an attacker was able to break out beyond the isolation of a container that they had succeeded in controlling in order to gain access to the host. Still a relatively young technology, Docker and other container services are likely to continue going through growing pains of vulnerabilities. Its very unlikely that you end up with a legacy, patched-up system nobody really wants to configure from scratch again, does this ring a bell? Introduced through: gnupg2/gnupg@2.2.12-1+deb10u1, subversion@1.10.4-1+deb10u1, mercurial@4.8.2-1+deb10u1, Medium severity vulnerability found in sqlite3/libsqlite3-0 Try to split your containers if they get too complex. Docker security best practices: What can you do to prevent this kind of security threats. Tested 200 dependencies for known issues, found 157 issues. This is really efficient for multiple reasons you probably know already, but from the point of view of security it can be seen as a risk that needs to be mitigated. Package manager: deb Besides, containers run on top of the host kernel by design. }, ca-certificates @ 20200601~deb10u1 Create an isolated user namespace to limit the maximum privileges of the containers over the host to the equivalent of a regular user. Description: Divide By Zero "name": "bash", libffi/libffi6 @ 3.2.1-9 Once you have your account, go to Account Settings and set a new password (you need this to create repos). The easiest way to do this is through automation and tools that can help to check that you are following best practices. information, see Scan images for Log4j 2 CVE. Use this tool for signing images, providing them with a level of encryption that can come in handy if your security is compromised. To add up to the problem, there are several different resources to safeguard: CPU, main memory, storage capacity, network bandwidth, I/O bandwidth, swapping there are some kernel resources that are not so evident, even more obscure resources such as user IDs (UIDs) exist!. Edit the /etc/docker/daemon.json file and add the conf key (be careful not to break json format): Restart the Docker daemon. You must update your Docker installation to the "ignoreSettings": null, It supports the following options: Your feedback is very important to us. Tested 0 dependencies for known issues, no vulnerable paths found. It goes without saying that if your host is compromised, then all the containers that are using it are also at risk. From AppSec and DevSecOps to Open Source Audits and Compliance we've got you covered, Docker Vulnerabilities: Container Security 101, For starters, containers are isolated software units which makes it harder for malicious actors to escalate from one, The reliance on the Linux kernel is at the core of many, #2 Docker Skeleton Runtime for Apache OpenWhisk, It would seem that 2018 was not a great year for Apache OpenWhisk users, highlighted here in, The fix can be found as it often is on the projects GitHub page with version, It is worth pointing out that despite the high ratings for this CVE as well as, #4 Windows Host Compute Service Shim (hcsshim).
