CVE-2011-4499 2 Cisco, Linksys 4 Linksys Wrt54g Router Firmware, Linksys Wrt54gs Router Firmware, Wrt54g and 1 more 2024-11-21 7.5 HIGH N/A
The UPnP IGD implementation in the Broadcom UPnP stack on the Cisco Linksys WRT54G with firmware before 4.30.5, WRT54GS v1 through v3 with firmware before 4.71.1, and WRT54GS v4 with firmware before 1.06.1 allows remote attackers to establish arbitrary port mappings by sending a UPnP AddPortMapping action in a SOAP request to the WAN interface, related to an "external forwarding" vulnerability.
CVE-2008-1268 1 Linksys 1 Wrt54g 2024-11-21 10.0 HIGH N/A
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-2008-1265 1 Linksys 1 Wrt54g 2024-11-21 7.8 HIGH N/A
The Linksys WRT54G router allows remote attackers to cause a denial of service (device restart) via a long username and password to the FTP interface.
CVE-2008-1264 1 Linksys 1 Wrt54g 2024-11-21 7.5 HIGH N/A
The Linksys WRT54G router has "admin" as its default FTP password, which allows remote attackers to access sensitive files including nvram.cfg, a file that lists all HTML documents, and an ELF executable file.
CVE-2008-1263 1 Linksys 1 Wrt54g 2024-11-21 4.0 MEDIUM N/A
The Linksys WRT54G router stores passwords and keys in cleartext in the Config.bin file, which might allow remote authenticated users to obtain sensitive information via an HTTP request for the top-level Config.bin URI.
CVE-2008-1247 1 Linksys 1 Wrt54g 2024-11-21 10.0 HIGH N/A
The web interface on the Linksys WRT54g router with firmware 1.00.9 does not require credentials when invoking scripts, which allows remote attackers to perform arbitrary administrative actions via a direct request to (1) Advanced.tri, (2) AdvRoute.tri, (3) Basic.tri, (4) ctlog.tri, (5) ddns.tri, (6) dmz.tri, (7) factdefa.tri, (8) filter.tri, (9) fw.tri, (10) manage.tri, (11) ping.tri, (12) PortRange.tri, (13) ptrigger.tri, (14) qos.tri, (15) rstatus.tri, (16) tracert.tri, (17) vpn.tri, (18) WanMac.tri, (19) WBasic.tri, or (20) WFilter.tri. NOTE: the Security.tri vector is already covered by CVE-2006-5202.
CVE-2006-5202 1 Linksys 1 Wrt54g 2024-11-21 5.0 MEDIUM N/A
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 1 Linksys 2 Wrt54g, Wrt54g V5 2024-11-21 7.5 HIGH N/A
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-2005-2916 1 Linksys 1 Wrt54g 2024-11-21 5.0 MEDIUM N/A
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-2005-2915 1 Linksys 1 Wrt54g 2024-11-21 5.0 MEDIUM N/A
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-2005-2914 1 Linksys 1 Wrt54g 2024-11-21 7.5 HIGH N/A
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 1 Linksys 1 Wrt54g 2024-11-21 5.0 MEDIUM N/A
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-2005-2799 1 Linksys 1 Wrt54g 2024-11-21 7.5 HIGH N/A
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-2005-2434 1 Linksys 1 Wrt54g 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2004-2606 1 Linksys 2 Befsr41 V3, Wrt54g 2024-11-20 7.5 HIGH N/A
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 1 Linksys 12 Befcmu10, Befn2ps4, Befsr11 and 9 more 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2024-8408 1 Linksys 2 Wrt54g, Wrt54g Firmware 2024-09-05 6.5 MEDIUM 9.8 CRITICAL
A vulnerability was found in Linksys WRT54G 4.21.5. It has been rated as critical. Affected by this issue is the function validate_services_port of the file /apply.cgi of the component POST Parameter Handler. The manipulation of the argument services_array leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
