Sunshine is a self-hosted game stream host for Moonlight. Starting in version 0.10.0 and prior to version 0.23.0, after unpairing all devices in the web UI interface and then pairing only one device, all of the previously devices will be temporarily paired. Version 0.23.0 contains a patch for the issue. As a workaround, restarting Sunshine after unpairing all devices prevents the vulnerability.
Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.
Name | Vendor | Start Version | End Version |

Such a scenario is commonly observed when:
In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
