CWE - 300 : Channel Accessible by Non-Endpoint ('Man-in-the-Middle')

CWE Definition http://cwe.mitre.org/data/definitions/300.html
Number of vulnerabilities: 3
Description The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint.In order to establish secure communication between two parties, it is often important to adequately verify the identity of entities at each end of the communication channel. Failure to do so adequately or consistently may result in insufficient or incorrect identification of either communicating entity. This can have negative consequences such as misplaced trust in the entity at the other end of the channel. An attacker can leverage this by interposing between the communicating entities and masquerading as the original entity. In the absence of sufficient verification of identity, such an attacker can eavesdrop and potentially modify the communication between the original entities.
