RFC: missing security-impacting changes from cdk diff "scrutiny report" #1299

rix0rrr · 2018-12-06T13:31:54Z

Summary

CDK libraries you depend on may affect your security posture. In order to increase confidence in stacks generated the CDK, we will attempt to identify when you're making changes that are potentially security-sensitive. You will see a prompt that looks like this:

This deployment will make potentially sensitive changes.
Please confirm you intend to make the following modifications:

Here's a known list of resources that are not currently included in the diff:

AWS::IAM::User
Network ACLs

I like this in principal, but is there a way to opt out? Sometimes I'm working on a dev setup, and it takes ~15-20 minutes to run all of my cdk deployments. Having to sit there and hit 'y' is actually quite a pain, and really slows me down. If I could run the deployment script I have and walk away from the computer, it would be great.

A flag like --accept-scrutiny-report would be really helpful for me.

davidbarsky · 2019-05-20T14:16:56Z

@insanitybit cdk deploy --require-approval=never might resolve your issue.

insanitybit · 2019-05-20T20:41:33Z

That looks like it'd be exactly what I want, thanks.

skinny85 · 2019-05-22T14:55:48Z

Resolving, as I think @insanitybit got the info they needed, feel free to re-open if not.

"CDK libraries you depend on may affect your security posture. In order to increase confidence in stacks generated the CDK, we will attempt to identify when you're making changes that are potentially security-sensitive. You will see a prompt that looks like this:"

My concern is more general than security related ( I am thinking to ask here 1st, maybe I am missing something ):
I've just noticed that cdk diff is not displaying the ChangeSet in the AWS CF Console.
Why ? Any reason for that ?
( seeing the ChangeSet in AWS CF Console history is too late with cdk deploy)

I like seeing the changes in console using cdk diff but they should be identical to what I should be visualising in AWS CF ChangeSet before applying them. Are they identical ?

oups - just noticed this has been closed ...

shivlaks · 2020-05-04T18:51:48Z

Still relevant.

Although the issue is closed, the conversation is not locked.

Using CfnInclude with template
https://s3.amazonaws.com/aws-transfer-resources/custom-idp-templates/aws-transfer-custom-idp-secrets-manager-apig.template.yml
cdk diff doesn't report any policy created with a role, is that expected?

skinny85 · 2020-06-22T17:13:35Z

It is not @gmiretti .... would you mind opening us a separate issue about this?

gmiretti · 2020-06-22T17:42:43Z

Bug reported as #8683

Thanks!

TrentonAdams · 2022-12-04T23:27:06Z

I receive this message...
(NOTE: There may be security-related changes not in this list. See #1299)

I'm unsure why the message is showing up. The diff shows me IAM changes and security group changes. Is that the reason it's showing up? It claims that there may be security related changes not in the list, but I don't know what that means. Could the message just tell me what other security related changes there are?

jorgemaroto-eb · 2023-02-09T19:16:24Z

Is this still an issue? I'm always seeing the warning, but not sure if it's kept updated.
I'm using:
├── aws-cdk-lib@2.64.0
├── aws-cdk@2.64.0

selsAT · 2023-02-15T09:20:38Z

yeah please remove the warning if its not relevant, PLEASE

nerdile · 2023-06-30T04:26:11Z

CDK Deploy gives a warning that implies there are known issues preventing IAM policy diffs from showing up in the confirmation prompt, and directs users to read this issue for more information.

However, this issue reads like you know there is an issue, but you don't know what it is. There is no information on this page.

Why is it necessary for developers to consult this page on every deployment? It seems unnecessary. Should I assume that all similar warnings from the CDK are equally irrelevant? Please consider what action you are requesting from developers when they deploy, and then reword the known issue warning to make it clear, or remove it if there is no action required from developers.

It is sometimes useful to see the delta between the current branch and the CODE CloudFormation stack. This change allows us to run: ```bash npm -w cdk run diff:code ``` to yield something like this: ```console Stack ServiceCatalogue-CODE (deploy-CODE-service-catalogue) Creating a change set, this may take a while...

Is this still relevant? I am seeing this issue linked in cdk deploy prompt and I am using 2.129.0. Could you please remove this warning message if its not relevant anymore. It creating confusion

jonasfschuh · 2024-09-15T13:46:24Z

I'm using CDK version 2.158.0 and for me this message still appears.
