Session Fixation in gunet/openeclass


Reported on

Sep 29th 2021


The Cookie before & after user login doesn't change

Proof of Concept

// PoC.js
1 Load website in a new browser
2 Get cookie before login
3 Login to website
4 Get cookie after login

Through other attack methods such as XSS, the attacker can store the user's cookies and access them later.
