The hash keys are the strings: "conf_mod", "conf_impact", etc.  The hash 
values are the arrays.

params = {
  "conf_mod"=>["20"],
  "conf_impact"=>["10"],
  "avail_impact"=>["5"],
  "integrity_impact"=>["5"],
  "authorization"=>["5"],
  "integrity_mod"=>["5"]
}

total = 0

params.each do |key, val|
  num_str = val[0]
  num = num_str.to_i
  total += num
end

puts total

--output:--
50
