Generally (new VBArray(arr).toArray()) should work on a SafeArray, which is what Request.BinaryRead returns. But it doesn't. I found this solution which I revised:

function GetRawRequestData() {
    var byteCount = Request.TotalBytes;
    var binary = Request.BinaryRead(byteCount)
    var reader = Server.CreateObject('ADODB.Recordset');
    reader.Fields.Append('x', 201, byteCount);
    reader.Open();
    reader.AddNew();
    reader.Fields(0).AppendChunk(binary);
    reader.update();
    return reader.Fields(0).Value;
}

Note that it might not handle encoding correctly. I didn't dive into what 201 for ADO datatype means, but it works.
