Introduce

This project can also be called Java vulnerability code.

Each vulnerability type code has a security vulnerability by default unless there is no vulnerability. The relevant fix code is in the comments or code. Specifically, you can view each vulnerability code and comments.

Due to the server expiration, the online demo site had to go offline.

• Docker
• IDEA
• Tomcat
• JAR

Docker

Start docker:

docker-compose pull
docker-compose up

Stop docker:

• Tomcat 8.5.11

IDEA

• git clone https://github.com/JoyChou93/java-sec-code
• Open in IDEA and click run button.

Example:

http://localhost:8080/rce/exec?cmd=whoami

return:

Viarus

Tomcat

• git clone https://github.com/JoyChou93/java-sec-code & cd java-sec-code
• Build war package by mvn clean package.
• Copy war package to tomcat webapps directory.
• Start tomcat application.

Example:

http://localhost:8080/java-sec-code-1.0.0/rce/runtime/exec?cmd=whoami

return:

Viarus

JAR

Change war to jar in pom.xml.

<groupId>sec</groupId>

RememberMe

Tomcat’s default JSESSION session is valid for 30 minutes, so a 30-minute non-operational session will expire. In order to solve this problem, the rememberMe function is introduced, and the default expiration time is 2 weeks.
