Remote Code Execution for Java Developers

NOTE: This is an educational repository with demo code. This code is NOT meant for production or deploying.

Open blog.md for the writeup associated with this repo.

Running the Demo

Running the server followed by running the client will result in the server being exploited. Note the code here only uses Java 8, but this example runs just fine on Java 11. Change the COMMAND string in Client.java to be the command you want the server to execute. It is currently set to the location of the calculator binary on MacOS.

Server:

cd $REPO_NAME/server
mvn clean compile package
java -jar ./target/server-0.0.1-SNAPSHOT.jar

Client:

cd $REPO_NAME/client
mvn clean compile package
java -jar ./target/client-0.0.1-SNAPSHOT.jar

Verify the server started calculator:

pstree -s "Calculator" | cat
