Detailed vulnerability description
The vulnerability allows a remote user to gain elevated access to an existing Graylog login session.
The vulnerability exists due to session fixation in the /api/system/sessions endpoint when reauthenticating with an existing session cookie. A remote privileged user can inject a chosen session cookie into a victim's browser to gain elevated access to an existing Graylog login session.
User interaction is required to present a spoofed login screen, and exploitation also requires successful session cookie injection into an existing browser session.
