Maven – security vulnerabilities

Maven is the clear leader amongst build tools in the Java and JVM ecosystem. Since Maven 2. When multiple users have access to a shared machine, or a settings. If you share settings. These authorized users would have a settings-security. In the event your builds run in a shared location, used by the wider team, you should encrypt secrets in the settings. To do this you will need to create a master password that you can store and share appropriately. You can create both the master password and server passwords using the Maven CLI by running the following command:.

For more information, look through the maven documentation page on storing secrets in the settings. By submitting this form you consent to us emailing you occasionally about our products and services.

In the previous example we showed the correct way to add secrets into your config files. There is also a wrong way, and we want to make sure you know this so you can avoid it! A legacy option on the CLI commands shown above is to provide a password on the command line for both encryption commands, such as the following:. While this would succeed and provide you with encrypted secrets, you should never type your secrets on a command line in plain text.

These secrets are stored in the console history and are easily retrievable. Maven repositories can be local or remote.


Remote repositories could include Maven Central, or a repository your organisation has set up, using artifactory or similar. You can see which repositories you are using in your build by looking in the element of your pom.

Validating that you are talking with the servers you want to connect with will reduce the chances of any Man In The Middle attacks, or more specifically a Resources Downloaded over Insecure Protocol vulnerability. To avoid this, always communicate to any repository via HTTPS, even if that repository is hosted by your own organization. To enable this, ensure your and elements in your pom. Number of active committers — Open source projects maintained by just one or two people can be risky because they tend to rely on a single individual for updates and releases.

Having a team of contributors reduces this risk significantly. Documented Security policies — Providing users with a procedure to report security issues will increase the chance that the project receives them in the first place. Equally, providing a mechanism that allows users to be notified of security issues and fixes as they arise allows users to consume dependencies in a more secure fashion.

Regular updates and releases — Make sure the projects you depend on are actively developed.

First of all, it will help with the future development of your own project, as you know that your dependencies will stay up-to-date with language features etc. Attackers target open source dependencies more and more, as library reuse provides many victims for a malicious hacker who tries to exploit a known vulnerability.

Using tools such as Snyk to test your Maven build artifacts will flag those dependencies that have known vulnerabilities. Additionally, it will suggest remediation advice, whether through version upgrades or with patches created by the Snyk security team. Snyk is available via a web UI as well as a CLI, so you can easily integrate it with your CI environment, and configure it to break your Maven build when vulnerabilities exist with a severity beyond your configured threshold.

You can use Snyk for free for open source projects or for private projects with a limited number of monthly tests. A checksum is designed to detect errors which may have been introduced during data transmission or storage.

It is important you check your dependency checksums for each of your project dependencies. In Maven 4, testing the checksums of every dependency will be done by default, however before then, use the -C flag on your Maven commands to enable checksum testing that will fail a build should the checksums not match. Properties are commonly used in Maven to act as placeholders in pom. The my.Comment 0. And seems to have been around since And, apparently, a thousand projects on GitHub are using it already.

In the past, I've gone manually through dependencies to check them against vulnerability databases, or, in many cases, I was just blissfully ignorant about any vulnerabilities that my dependencies had. The purpose of this post is just that - to recommend the OWASP dependency check maven plugin as a must-have in practically every maven project there are dependency-check tools for other build systems as well.

When you add the plugin it generates a report. Initially, you can go and manually upgrade the problematic dependencies I upgraded two of those in my current projector suppress the false positives e. Then you can configure a threshold for vulnerabilities and fail the build if new ones appear - either by you adding a vulnerable dependency or in case a vulnerability is discovered in an existing dependency. All of that is shown on the examples page and is pretty straightforward.

I'd suggest adding the plugin immediately, it's a must-have:. It's not all roses, of course. People on Reddit complained that while the plugin caches stuff locally, it can still slow down your build significantly.

Now, checking dependencies for vulnerabilities is just one small aspect of having your software secure and it shouldn't give you a false sense of security a sort-of "I have my dependencies checked, therefore my system is secure" fallacy. But it's an important aspect. And having that check automated is a huge gain. See the original article here. Over a million developers have joined DZone.

Washington, DC.How to automatically detect vulnerable third-party libraries as a part of your build process, integrate it with CI and track vulnerable dependencies over time? Making sure your application contains security vulnerabilities is not only about securing your own code. Your application likely contains a lot of other libraries - third-party dependencies. They introduce a lot of security vulnerabilities as well, many of which you are not even aware.

Once they are discovered, they are usually fixed in a new version.

maven – security vulnerabilities

When you are using an old version of a library, without recent security fixes, you are at risk. When an attacker identifies you are using an old version of particular dependency, they can easily exploit that.

There are even public databases of security vulnerabilities of third-party libraries, so it is quite easy to determine which ones to exploit. Components, such as libraries, frameworks, and other software modules, almost always run with full privileges.

If a vulnerable component is exploited, such an attack can facilitate serious data loss or server takeover. Applications using components with known vulnerabilities may undermine application defenses and enable a range of possible attacks and impacts. Ideally, you would want to keep your dependencies always up to date. It is unfortunately not always possible. You may encounter a situation, where it is not so easy to update one of your dependencies.

Maybe the API changed and the upgrade would involve too much refactoring. Or one of your dependencies may rely on an older version of the dependency you would want to upgrade.

Or your dependencies would be incompatible in some other way. It would be nice to know exactly which vulnerabilities you current dependencies contain and how severe they are, right? Turns out there are whole databases of component security vulnerabilities such as the National Vulnerability Database.

It is, however, not realistic to check manually all your dependencies and as we already know, an average app has of themnot to mention doing this frequently. There has to be a better way. Good news is that there is a way to check your application against the National Vulnerability Database automatically.

Such as - Maven plugin, Jenkins plugin, SonarQube plugin and more. Dependency check provides integration with several common build tools - Maven PluginGradle plugin or Ant task.

Alternatively, there is also Command Line Tool. Common usage scenario would be introducing Maven Dependency Check plugin as a part of your maven build:. An example application using Dependency Check Maven plugin can be found here. Here is the example of a report generated. This way you can integrate Dependency check as a part of your Jenkins Job and check generated reports after it is run.
