Linksys : Security Vulnerabilities, CVEs,

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.

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.

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.

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.

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.

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.

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.

GlobalSunTech Wireless Access Points (1) WISECOM GL2422AP-0T, and possibly OEM products such as (2) D-Link DWL-900AP+ B1 2.1 and 2.2, (3) ALLOY GL-2422AP-S, (4) EUSSO GL2422-AP, and (5) LINKSYS WAP11-V2.2, allow remote attackers to obtain sensitive information like WEP keys, the administrator password, and the MAC filter via a "getsearch" request to UDP port 27155.

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.

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.

Buffer overflow in the system log viewer of Linksys BEFSX41 1.44.3 allows remote attackers to cause a denial of service via an HTTP request with a long Log_Page_Num variable.

Linksys WAP55AG 1.07 allows remote attackers with access to an SNMP read only community string to gain access to read/write communtiy strings via a query for OID 1.3.6.1.4.1.3955.2.1.13.1.2.

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.

Absolute path traversal vulnerability in main.cgi in Linksys WVC11B Wireless-B Internet Video Camera allows remote attackers to read arbitrary files via an absolute pathname in the next_file parameter.

Cross-site scripting (XSS) vulnerability in main.cgi in Linksys WVC11B Wireless-B Internet Video Camera allows remote attackers to inject arbitrary web script or HTML via the next_file parameter.

The Web interface in Linksys WRT54G 2.02.7 and BEFSR41 version 3, with the firewall disabled, allows remote attackers to attempt to login to an administration web page, even when the configuration specifies that remote administration is disabled.

Linksys PSUS4 running firmware 6032 allows remote attackers to cause a denial of service (device crash) via an HTTP POST request containing an unknown parameter without a value.

Linksys WET11 1.5.4 allows remote attackers to change the password without providing the original password via the data parameter to changepw.html.

Linksys WRT54G router uses the same private key and certificate for every router, which allows remote attackers to sniff the SSL connection and obtain sensitive information.

Unknown vulnerability in Linksys WRT54GS wireless router with firmware 4.50.6, with WPA Personal/TKIP authentication enabled, allows remote clients to bypass authentication by connecting without using encryption.

Buffer overflow in apply.cgi in Linksys WRT54G 3.01.03, 3.03.6, and possibly other versions before 4.20.7, allows remote attackers to execute arbitrary code via a long HTTP POST request.

Linksys WRT54G router allows remote attackers to cause a denial of service (CPU consumption and server hang) via an HTTP POST request with a negative Content-Length value.

ezconfig.asp in Linksys WRT54G router 3.01.03, 3.03.6, non-default configurations of 2.04.4, and possibly other versions, does not use an authentication initialization function, which allows remote attackers to obtain encrypted configuration information and, if the key is known, modify the configuration.

ezconfig.asp in Linksys WRT54G router 3.01.03, 3.03.6, non-default configurations of 2.04.4, and possibly other versions, uses weak encryption (XOR encoding with a fixed byte mask) for configuration information, which could allow attackers to decrypt the information and possibly re-encrypt it in conjunction with CVE-2005-2914.
