Channel Accessible by Non-Endpoint

CWE-300

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.

We track 17 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 7.9.

How this weakness is prevented

  • Implementation: 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. Always fully authenticate both ends of any communications channel.
  • Architecture and Design: Adhere to the principle of complete mediation.
  • Implementation: A certificate binds an identity to a cryptographic key to authenticate a communicating party. Often, the certificate takes the encrypted form of the hash of the identity of the subject, the public key, and information such as time of issue or expiration using the issuer's private key. The certificate can be validated by deciphering the certificate with the issuer's public key. See also X.509 certificate signature chains and the PGP certification structure.
