Java Sec Code

Java sec code is a very powerful and friendly project for learning Java vulnerability code.

中文文档

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.

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.
