In both cases, after the user is authenticated on the server, the attacker can take over (hijack) the session by using the same session ID for their own browser session.

Can session puzzling be used to bypass authentication or authorization?

Session puzzle enables the attackers to bypass authentication, Impersonate legitimate users, elevate privileges, bypass flow restrictions, and even execute additional attacks.

What is blind hijacking?

A type of session hijacking in which the cybercriminal does not see the target host’s response to the transmitted requests.
