VER-EVA-EIR Evaluate Internet-Reachability

Providers MUST evaluate detected vulnerabilities, considering the context of the cloud service offering, to determine if they are internet-reachable vulnerabilities.

Notes

FedRAMP focuses on internet-reachable (rather than internet-accessible) to ensure that any service that might receive a payload from the internet is prioritized if that service has a vulnerability that can be triggered by processing the data in the payload.

The simplest way to prevent exploitation of internet-reachable vulnerabilities is to intercept, inspect, filter, sanitize, reject, or otherwise deflect triggering payloads before they are processed by the vulnerable resource; once this prevention is in place the vulnerability should no longer be considered an internet-reachable vulnerability.

A classic example of an internet-reachable vulnerability on systems that are not typically internet-accessible is SQL injection, where an application stack behind a load balancer and firewall with no ability to route traffic to or from the internet can receive a payload indirectly from the internet that triggers the manipulation or compromise of data in a database that can only be accessed by an authorized connection from the application server on a private network.

Another simple example is the infamous Log4Shell (https://en.wikipedia.org/wiki/Log4Shell) vulnerability from 2021, where exploitation was possible via vulnerable internet-reachable resources deep in the application stack that were often not internet-accessible themselves.
