LinkSys EtherFast BEFSR41 Cable/DSL routers running firmware before 1.39.3 Beta allows a remote attacker to view administration and user passwords by connecting to the router and viewing the HTML source for (1) index.htm and (2) Password.htm.
DHCP on Linksys BEFSR11, BEFSR41, BEFSR81, and BEFSRU31 Cable/DSL Routers, firmware version 1.45.7, does not properly clear previously used buffer contents in a BOOTP reply packet, which allows remote attackers to obtain sensitive information.
