Either (or both) of the ports UDP:161 and UDP:162 are open. This usually indicates an SNMP agent is present. Having such an agent open to outside access may be used to compromise sensitive information, and can be used to cause a Denial of Service attack. Certain SNMP agents may be vulnerable to root compromise attacks. More Information: http://www.securiteam.com/exploits/Patrol_s_SNMP_Agent_3_2_can_lead_to_root_compromise.html
