Linksys EtherFast routers default SNMP community string information leak
|linksys-etherfast-default-snmp (7827)||Medium Risk|
Linksys EtherFast could allow a remote attacker to gain sensitive information about network traffic that is being handled by the router. A remote attacker can query an affected router with the default community of (public) to cause the router to make the querying system the SNMP trap host, which would cause certain information about network traffic to be dumped to the host. An attacker could use this to launch a distributed denial of service attack (DDoS) against a targeted host by exploiting this vulnerability on a number of affected routers.
No remedy available as of December 1, 2013.
