Improper Enforcement of Message Integrity During Transmission in a Communication Channel

Opis

The product establishes a communication channel with an endpoint and receives a message from that endpoint, but it does not sufficiently ensure that the message was not modified during transmission.

Attackers might be able to modify the message and spoof the endpoint by interfering with the data as it crosses the network or by redirecting the connection to a system under their control.

Skutki

• Integrity, Confidentiality

  Gain Privileges or Assume Identity

  If an attackers can spoof the endpoint, the attacker gains all the privileges that were intended for the original endpoint.
