CVE-2008-1268 [CRITICAL] CWE-287 CVE-2008-1268: The FTP server on the Linksys WRT54G 7 router with 7.00.1 firmware does not verify authentication cr The FTP server on the Linksys WRT54G 7 router with 7.00.1 firmware does not verify authentication credentials, which allows remote attackers to establish an FTP session by sending an arbitrary username and password.

CVE-2006-5202 [MEDIUM] CVE-2006-5202: Linksys WRT54g firmware 1.00.9 does not require credentials when making configuration changes, which Linksys WRT54g firmware 1.00.9 does not require credentials when making configuration changes, which allows remote attackers to modify arbitrary configurations via a direct request to Security.tri, as demonstrated using the SecurityMode and layout parameters, a different issue than CVE-2006-2559.

CVE-2006-2559 [HIGH] CVE-2006-2559: Linksys WRT54G Wireless-G Broadband Router allows remote attackers to bypass access restrictions and Linksys WRT54G Wireless-G Broadband Router allows remote attackers to bypass access restrictions and conduct unauthorized operations via a UPnP request with a modified InternalClient parameter, which is not validated, as demonstrated by using AddPortMapping to forward arbitrary traffic.

CVE-2005-2799 [HIGH] CVE-2005-2799: Buffer overflow in apply.cgi in Linksys WRT54G 3.01.03, 3.03.6, and possibly other versions before 4 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.

CVE-2005-2914 [HIGH] CVE-2005-2914: ezconfig.asp in Linksys WRT54G router 3.01.03, 3.03.6, non-default configurations of 2.04.4, and pos 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.

CVE-2005-2912 [MEDIUM] CVE-2005-2912: Linksys WRT54G router allows remote attackers to cause a denial of service (CPU consumption and serv 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.

CVE-2005-2915 [MEDIUM] CVE-2005-2915: ezconfig.asp in Linksys WRT54G router 3.01.03, 3.03.6, non-default configurations of 2.04.4, and pos 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.

CVE-2005-2916 [MEDIUM] CVE-2005-2916: Linksys WRT54G 3.01.03, 3.03.6, 4.00.7, and possibly other versions before 4.20.7, does not verify u Linksys WRT54G 3.01.03, 3.03.6, 4.00.7, and possibly other versions before 4.20.7, does not verify user authentication until after an HTTP POST request has been processed, which allows remote attackers to (1) modify configuration using restore.cgi or (2) upload new firmware using upgrade.cgi.

CVE-2004-2606 [HIGH] CVE-2004-2606: The Web interface in Linksys WRT54G 2.02.7 and BEFSR41 version 3, with the firewall disabled, allows 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.

CVE-2004-0580 [MEDIUM] CVE-2004-0580: DHCP on Linksys BEFSR11, BEFSR41, BEFSR81, and BEFSRU31 Cable/DSL Routers, firmware version 1.45.7, 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.
