Summary of Changes

Hello @barakharyati, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request is a Proof of Concept (PoC) demonstrating a potential remote code execution vulnerability within the infra/iam directory. It replaces the existing IAM management setup with a new Terraform configuration that executes an arbitrary shell script. The script attempts to exfiltrate sensitive repository and cloud credential information, highlighting a critical security concern. This PR is explicitly marked as a test and should not be merged.

Highlights

• IAM Infrastructure Overhaul: The existing Terraform IAM configuration, including main.tf, config.auto.tfvars, users.tf, and all custom role definitions (roles/*.yaml), along with related Python scripts and documentation, has been entirely removed.
• Introduction of External Script Execution: A new Terraform file (my.tf) has been added, which is configured to execute an external shell script (myscript.sh) during Terraform operations.
• Remote Code Execution (RCE) PoC: The myscript.sh file contains commands designed to demonstrate remote code execution capabilities. This includes attempts to read sensitive .git/config files, configure git, create and push a new branch, and exfiltrate various credentials (git, AWS, GCP) and environment variables to an external webhook.
• Explicit "Do Not Merge" Status: The pull request title explicitly states "Test2poc do not merge", indicating its nature as a proof of concept and its unsuitability for merging into the main codebase.
