Issue #11031 has been updated by Nigel Kersten.

Adrien, what are you planning to do here? Just filter out the facts that are 
sensitive? Filter them out only if the root user is running a process?

Bug #11031: capturing ec2 userdata as a fact may be a security risk
https://projects.puppetlabs.com/issues/11031

Author: Dan Bode
Status: Accepted
Priority: Normal
Assignee: Adrien Thebo
Category: 
Target version: 1.6.x
Keywords: 
Branch: 
Affected Facter version: 


When cloud-init is used for bootstrapping nodes, a script contained in the 
userdata is often passed to the node to perform bootstrapping.

In the case of cloud formation, this script often contains IAM credentials 
(access code/secret code) that are used to call cfn-init.

In my integration of PE with cloudformation, I can see the AWS credentials in 
the inventory service when running  b/c they are captured as a part of the ec2 
metadata.

This is not that big of a deal for my use case b/c the credentials only refer 
to a temporary account that only has the permissions to read metadata from 
cloudformation instances.

In general, I have concerns over rather capturing userdata with facter may 
potentially (and unexpectedly) expose a user's credentials in some cases.
