vulnerable-spring-app's Introduction

Security in Spring Boot

This repository contains a project with a number of vulnerabilities that you will need to fix.

Thymeleaf

This project uses a Java templating library called "Thymeleaf". We do not cover this in this course, but it should be easy for you to understand. You can see an overview of everything you need to know using this resource https://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.html#using-thtext-and-externalizing-text.

Pick 2 vulnerabilities and fix them.

XSS

We're able to send arbitrary blocks of text and HTML markup to the server and render them. Explore the thymeleaf docs to understand how this is happening and find a fix

SQL Injection

It's possible to extend one of the requests so that we can perform dangerous queries against the database

Identification and Authentication failures

The authentication is flawed and it is not using password hashing

Security logging and monitoring failures

We do not log any of the key user events

Cryptographic Failure

We're using out of date and/or flawed cryptography strategies
