The Java Sec Code project is a robust and user-friendly tool designed for those eager to delve into Java vulnerability coding. This guide aims to simplify your journey in understanding and utilizing this project effectively.

Introduction to Java Sec Code

Java Sec Code, also known as Java vulnerability code, consists of a variety of vulnerability types, each paired with a corresponding security code. It’s essential to study these vulnerabilities to identify potential issues in Java applications. The fix codes are often included within comments or nearby in the code itself. This project serves as a hands-on learning platform for developers to understand security vulnerabilities and how to remedy them.

Installation and Setup

Before you dive into exploring vulnerabilities, you’ll need to set up the environment. The application uses MyBatis for auto-injection, so ensure your MySQL server is running with the appropriate database configurations.

Prerequisites

• MySQL Server
• Java (1.8.0_102 or later)
• Tomcat (8.5.11)

Configuration Steps

1. Run the MySQL server and configure the following properties in the application:

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/java_sec_code
spring.datasource.username=root
spring.datasource.password=woshishujukumima

2. To use Docker, execute the following commands:
• Start Docker: docker-compose pull
• Bring up Docker: docker-compose up
• Stop Docker: docker-compose down

Running in Different Environments

Using IDEA

1. Clone the repository: git clone https://github.com/JoyChou93/java-sec-code
2. Open in IDEA and hit the run button.
3. Access the application: http://localhost:8080/rceexec?cmd=whoami

Using Tomcat

1. Clone the repository: git clone https://github.com/JoyChou93/java-sec-code
2. Change directory and build the WAR package: cd java-sec-code && mvn clean package
3. Copy the WAR package to the Tomcat webapps directory and start Tomcat.
4. Access the application: http://localhost:8080/java-sec-code-1.0.0/rce/runtimeexec?cmd=whoami

Using JAR

To run as JAR, change the packaging to jar in the pom.xml file:

<packaging>war</packaging>

Then, build and run the application similar to before:

git clone https://github.com/JoyChou93/java-sec-code cd java-sec-code mvn clean package -DskipTests java -jar target/java-sec-code-1.0.0.jar

Authentication Process

To access the application, navigate to the login page: http://localhost:8080/login. Use the following credentials:

• Username: admin
• Password: joychou123

Troubleshooting Common Issues

Should you encounter issues while setting up or running the application, consider the following troubleshooting strategies:

• Ensure your MySQL server is properly configured and running.
• Double-check your environment variables for JAVA_HOME and other dependencies.
• If Docker isn’t starting as expected, verify that Docker is installed correctly and running.
