Basic Java Web Server

This project is a Java based multithreaded TCP web server that implements responses for HTTP 200, 301, and 404 codes. It was made using Java 8 and runs by default on port 6789 of localhost.

Vulnerability

The server has the vulnerable Apache Commons Collection 3.1 in its Classpath which can lead to code execution. It is to be found in file DeserServer/src/Connection.java, where a base64 string gets decoded and deserialized, as well as cast to an object.

Usage

  • Compiling the Program

    • Open console and type javac src/WebServer.java

  • Running the Program

    • Type java src/WebServer to run the program or use your preferred IDE

  • Testing HTTP 200 OK:

    • In your browser of choice type localhost:6789 into the address bar. A basic webpage should appear.
