CAPEC-22 Metadata
Likelihood of Attack
High
Typical Severity
High
Overview
Summary
An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
Prerequisites
Server software must rely on client side formatted and validated values, and not reinforce these checks on the server side.
Potential Solutions / Mitigations
Design: Ensure that client process and/or message is authenticated so that anonymous communications and/or messages are not accepted by the system. Design: Do not rely on client validation or encoding for security purposes. Design: Utilize digital signatures to increase authentication assurance. Design: Utilize two factor authentication to increase authentication assurance. Implementation: Perform input validation for all remote content.
