Detailed vulnerability description

The vulnerability allows a remote attacker to impersonate other users.

The vulnerability exists due to authentication bypass by capture-replay in the login authentication mechanism when processing a stolen login token without protocol encryption. A remote attacker can replay captured login data to impersonate other users.

User interaction is required to capture a victim's login, such as by tricking the victim into joining an attacker-controlled server. Captured tokens expire after a limited time, typically within 2-3 days.
