This vulnerability allows the successful attacker to gain unauthorized access to a configuration web page delivered by the integrated web Server of EIBPORT.
This issue affects EIBPORT V3 KNX: through 3.9.8; EIBPORT V3 KNX GSM: through 3.9.8.
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.
