An intentionally vulnerable application, to test Snyk's Runtime Monitoring offering.

The docs there explain what the tool achieves. You might want to read them before continuing, to get a feel for what this demo is going to show. Once you've run the demo, you definitely will want to read them to learn how to integrate the agent into your application!

The runtime monitoring tool is open source. The documentation on how to get started with contributing to the agent is hosted on that project.

How?

Everything should drive from Gradle, which is bundled in this repository.

You just need a Java JDK 8 or above, installed and working.

The examples use ./gradlew everywhere. On Windows, use gradlew.bat in place of ./gradlew, for example, gradlew.bat startWithAgent.

First, check you can build:

$ ./gradlew startWithAgent
...

  You must specify a project ID.
  
  Please run `snyk monitor`, collect the id from the results' settings page,
    then re-run `startWithAgent` using that ID.

  For example (you *must* change the projectId!):

     ./gradlew -PprojectId=4567901-2345-6789-0123-45678912345 startWithAgent
...

Then, run snyk cli:

$ snyk monitor

Now, you can start the app with the agent:

$ ./gradlew -PprojectId=4567901-2345-6789-0123-45678912345 startWithAgent

...

This will set up a snyk-agent.properties containing your projectId, and then start the application using the latest Snyk Java Runtime Agent.

Exploit!

You can visit the application, and exploit it by uploading a zip file. For example, you can try the provided zip-slip.zip.

Alternatively, you can upload from the command line, using:

$ ./gradlew runExploit
> Task :runExploit
The file contains these entries:
 * good.txt


An exploit attempt has been made.

If your application is protected, then you should shortly see the warning on your Snyk dashboard.
