Greetings,

Suppose I have a class foo that host A gets via its catalog. Suppose host B does not have foo in its catalog. Can host B do anything malicious to obtain the sensitive data in foo?

My puppet master is using an ENC to generate the classification of each host and then a rolesĀ + profiles design pattern and hiera for specific data.

Thanks for any hints or answers!


It is important that your server side logic uses $trusted when classifying on node since other facts cannot be trusted.

If B is compromised a malicious user could spoof facts in a request and pretend to be A. It cannot however spoof the certificate - and it contains the information that is in $trusted.
