Description
ScadaBR 1.12.4 is vulnerable to Session Fixation. The application assigns a JSESSIONID session cookie to unauthenticated users and does not regenerate the session identifier after successful authentication. As a result, a session created prior to login becomes authenticated once the victim logs in, allowing an attacker who knows the session ID to hijack an authenticated session.
