![]() ![]() ![]() At the end we should get the message: BUILD SUCCESS. Maven will do its thing, running tests, compiling dependencies, etc. ![]() Time to build our AntiSamy jar: mvn package this is fine - we're not making changes, we're building a version. This will result in a warning that You are in 'detached HEAD' state. The following command will list the tags, with the most recent first: git tag -n -sort =-creatordateĪt the time I'm writing this, the most recent release is v1.6.6, so we'll check out the code there: git checkout v1.6.6 We could build here, but it's probably better if we checkout a specific release tag before building, so that we know exactly what we're getting. So, let's hop into the command line and get started.ĭownload the project from GitHub: git clone directories into the project: cd antisamy As we'll see later on, this will also enable us to build the jars for any version we want, even if hasn't been released yet. We're going to use the AntiSamy project on GitHub to build the jars that we need. You'll know you're good to go when you can run the mvn -version command in your terminal. Maven is also available via Homebrew and MacPorts for macOS and Chocolatey for Windows (though I've never tried any of those approaches). The installation of Apache Maven is a simple process of extracting the archive and adding the bin folder with the mvn command to the PATH. There are any number of guides for installing Maven, but the official install guide is probably a good place to start. This is relatively painless and totally worth it if you're looking to integrate Java projects with a ColdFusion application. If you haven't used Maven before, don't stop reading! Just like npm or yarn can make working with JavaScript packages easier, Maven is a very helpful tool when you're working with Java projects - and we only need to use a handful of commands. It's worth noting that the approach here will be a little different because we'll use Maven, which will actually do a lot of the heavy lifting for us. With typical detail and insight, Ben Nadel recently blogged about his AntiSamy update process. Regardless, we need to get the AntiSamy jar file, along with all of its dependencies, and load them into our application. I'll cover some of the differences later. The basic process of using Antisamy with ColdFusion varies, depending on if you're using Adobe ColdFusion or Lucee. Reading the release notes reveals that these are not just updating vulnerable dependencies (including log4j), but also valuable improvements, such as schema validation for policy files and reducing the risk of reverse tabnabbing via the adddition of rel="noopener" to anchors when target="_blank" is set. While updating to the latest version of AntiSamy (actually, the snapshot of an upcoming release - more on that later) I documented the process, and particularly how Maven can make it easier.įor a few years the OWASP AntiSamy project appeared to be strictly in maintenance mode, but development has been very active over the past two years, with 12 releases since March 2020. In ColdFusion applications, I tend to use the AntiSamy Java library to sanitize user-supplied input. ![]()
