CWE-923—Improper Restriction of Communication Channel to Intended Endpoints

Weakness Name

Improper Restriction of Communication Channel to Intended Endpoints

Description

The product establishes a communication channel to (or from) an endpoint for privileged or protected operations, but it does not properly ensure that it is communicating with the correct endpoint.

Attackers might be able to spoof the intended endpoint from a different system or process, thus gaining the same level of access as the intended endpoint. While this issue frequently involves authentication between network-based clients and servers, other types of communication channels and endpoints can have this weakness.

Common Consequences

Scope:

Integrity, Confidentiality

Impact:

Gain Privileges or Assume Identity

Notes:

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