How to Fix CVE-2023-30618

To remediate this vulnerability, upgrade all affected Kitchen terraform dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

kitchen-terraform fixed: 7.0.1 
Upgrade kitchen-terraform to 7.0.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for kitchen-terraform

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-30618, inspect your project dependencies for Kitchen terraform:

inspect dependencies for kitchen-terraform

Analyze the terminal output to locate any version of Kitchen terraform in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.0.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-532: Insertion of Sensitive Information into Log File, where the product writes sensitive information to a log file. In Kitchen terraform, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary Kitchen-Terraform v7.0.0 introduced a regression which caused all Terraform output values, including sensitive values, to be printed at the `info` logging level during the `kitchen converge` action. Prior to v7.0.0, the output values were printed at the `debug` level to avoid writing sensitive values to the terminal by default. ### Original Report @brettcurtis: > Hopefully, I'm not doing something stupid here, but I'm seeing sensitive outputs printed in the kitchen output. You can check this action for an example: https://github.com/osinfra-io/terraform-google-project/actions/runs/4700065515/jobs/8334277309#step:5:215 > > It's not really a sensitive value just used it as an example.
