Description: It is possible to cause a Denial of Service by requesting a certain URL from the management interface. If one requests: http://192.168.1.1/Gozila.cgi? The EtherFast Cable/DSL Router crashes. If management is enabled on the external interface this may also be done from remote. But it could also be done if malicious websites include an image tag which requests the URL. Solution: This affects firmware versions earlier than 1.42.7 Current firmware is 1.43 http://www.linksys.com/download/firmware.asp?fwid=1 Provided and/or discovered by: Discovered by Jeep 94 Published by David Endler, iDEFENSE
