/bin/login.php in the Web Panel on the Airtame HDMI dongle with firmware before 3.0 allows an attacker to set his own session id via a Cookie: PHPSESSID= header. This can be used to achieve persistent access to the admin panel even after an admin password change.
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.

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.
