```powershell # PowerShell script to check for role juggling possibilities using AWS CLI
Check for AWS CLI installation
if (-not (Get-Command "aws" -ErrorAction SilentlyContinue)) { Write-Error "AWS CLI is not installed. Please install it and configure it with 'aws configure'." exit }
Function to list IAM roles
function List-IAMRoles { aws iam list-roles --query "Roles[*].{RoleName:RoleName, Arn:Arn}" --output json }
Initialize error count
$errorCount = 0
List all roles
$roles = List-IAMRoles | ConvertFrom-Json
Attempt to assume each role
foreach ($role in $roles) { $sessionName = "RoleJugglingTest-" + (Get-Date -Format FileDateTime) try { $credentials = aws sts assume-role --role-arn $role.Arn --role-session-name $sessionName --query "Credentials" --output json 2>$null | ConvertFrom-Json if ($credentials) { Write-Host "Successfully assumed role: $($role.RoleName)" Write-Host "Access Key: $($credentials.AccessKeyId)" Write-Host "Secret Access Key: $($credentials.SecretAccessKey)" Write-Host "Session Token: $($credentials.SessionToken)" Write-Host "Expiration: $($credentials.Expiration)"
Set temporary credentials to assume the next role
$env:AWS_ACCESS_KEY_ID = $credentials.AccessKeyId $env:AWS_SECRET_ACCESS_KEY = $credentials.SecretAccessKey $env:AWS_SESSION_TOKEN = $credentials.SessionToken
Try to assume another role using the temporary credentials
foreach ($nextRole in $roles) { if ($nextRole.Arn -ne $role.Arn) { $nextSessionName = "RoleJugglingTest-" + (Get-Date -Format FileDateTime) try { $nextCredentials = aws sts assume-role --role-arn $nextRole.Arn --role-session-name $nextSessionName --query "Credentials" --output json 2>$null | ConvertFrom-Json if ($nextCredentials) { Write-Host "Also successfully assumed role: $($nextRole.RoleName) from $($role.RoleName)" Write-Host "Access Key: $($nextCredentials.AccessKeyId)" Write-Host "Secret Access Key: $($nextCredentials.SecretAccessKey)" Write-Host "Session Token: $($nextCredentials.SessionToken)" Write-Host "Expiration: $($nextCredentials.Expiration)" } } catch { $errorCount++ } } }
Reset environment variables
Remove-Item Env:\AWS_ACCESS_KEY_ID Remove-Item Env:\AWS_SECRET_ACCESS_KEY Remove-Item Env:\AWS_SESSION_TOKEN } else { $errorCount++ } } catch { $errorCount++ } }
Output the number of errors if any
if ($errorCount -gt 0) { Write-Host "$errorCount error(s) occurred during role assumption attempts." } else { Write-Host "No errors occurred. All roles checked successfully." }
Write-Host "Role juggling check complete."
