Linksys WET11 firmware 1.31 and 1.32 allows remote attackers to cause a denial of service (crash) via a packet containing the device's hardware address as the source MAC address in the DLC header.

Linksys EtherFast Cable/DSL BEFSR11, BEFSR41 and BEFSRU31 with the firmware 1.42.7 upgrade installed opens TCP port 5678 for remote administration even when the "Block WAN" and "Remote Admin" options are disabled, which allows remote attackers to gain access.

Buffer overflow in the Embedded HTTP server, as used in (1) D-Link DI-804 4.68, Dl-704 V2.56b6, and Dl-704 V2.56b5 and (2) Linksys Etherfast BEFW11S4 Wireless AP + Cable/DSL Router 1.37.2 through 1.42.7 and Linksys WAP11 1.3 and 1.4, allows remote attackers to cause a denial of service (crash) via a long header, as demonstrated using the Host header.

Buffer overflow in the Web management interface in Linksys BEFW11S4 wireless access point router 2 and BEFSR11, BEFSR41, and BEFSRU31 EtherFast Cable/DSL routers with firmware before 1.43.3 with remote management enabled allows remote attackers to cause a denial of service (router crash) via a long password.

The remote management web server for Linksys BEFSR41 EtherFast Cable/DSL Router before firmware 1.42.7 allows remote attackers to cause a denial of service (crash) via an HTTP request to Gozila.cgi without any arguments.

VPN Server module in Linksys EtherFast BEFVP41 Cable/DSL VPN Router before 1.40.1 reduces the key lengths for keys that are supplied via manual key entry, which makes it easier for attackers to crack the keys.

Linksys EtherFast BEFN2PS4, BEFSR41, and BEFSR81 Routers, and possibly other products, allow remote attackers to gain sensitive information and cause a denial of service via an SNMP query for the default community string "public," which causes the router to change its configuration and send SNMP trap information back to the system that initiated the query.

Atmel Firmware 1.3 Wireless Access Point (WAP) allows remote attackers to cause a denial of service via a SNMP request with (1) a community string other than "public" or (2) an unknown OID, which causes the WAP to deny subsequent SNMP requests.

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.

SNMP service in Atmel 802.11b VNET-B Access Point 1.3 and earlier, as used in Netgear ME102 and Linksys WAP11, accepts arbitrary community strings with requested MIB modifications, which allows remote attackers to obtain sensitive information such as WEP keys, cause a denial of service, or gain access to the network.
