Session tokens are not invalidated on logout in heroiclabs/nakama
Reported on
May 24th 2022
Description
The session cookie is not invalidated on logout so, it can be used after logout as well.
Proof of Concept
Login to the Nakama console.
Intercept the request. Below is a sample request:
GET /v2/console/user HTTP/1.1
Host: localhost:7351
Accept: application/json, text/plain, */*
Authorization: Bearer <token>
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.74 Safari/537.36
Referer: http://localhost:7351/
Accept-Encoding: gzip, deflate
Accept-Language: en-US,en;q=0.9
Connection: close
Logout from the application.
Replay the request. Response is received as an authorized user.
Impact
Old session tokens can be used to authenticate to the application and send authenticated requests.
