Session fixation vulnerability in TCP/IP function included in the firmware of GT14 Model of GOT 1000 series (GT1455-QTBDE CoreOS version 05.65.00.BD and earlier, GT1450-QMBDE CoreOS version 05.65.00.BD and earlier, GT1450-QLBDE CoreOS version 05.65.00.BD and earlier, GT1455HS-QTBDE CoreOS version 05.65.00.BD and earlier, and GT1450HS-QMBDE CoreOS version 05.65.00.BD and earlier) allows a remote unauthenticated attacker to stop the network functions of the products via a specially crafted packet.

Weakness

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.

Affected Software

Name Vendor Start Version End Version
Coreos Mitsubishielectric * 05.65.00.bd (including)

Extended Description

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.
