Not sure why tonight I found a bunch of things to start topics on but, since this is a pretty popular wireless router and people could potentially get hacked without anyone even coming into your house, i'd call it important.
"Successful exploitation of this vulnerability would allow an
unauthenticated user the ability to modify the configuration of the
affected router, including the password. This could allow firewall rules
to be changed, installation of a new firmware with other features, or
denial of service. Exploitation of this vulnerability would require that
an attacker can connect to the web management port of the router. The
httpd is running by default but is only accessible via the LAN ports or
the WLAN (wireless LAN)."
