CVSS v3.1 |
| 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. |
| 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. |
| Linksys WRT54G routers version 5 (running VXWorks) allow remote attackers to cause a denial of service by sending a malformed DCC SEND string to an IRC channel, which causes an IRC connection reset, possibly related to the masquerading code for NAT environments, and as demonstrated via (1) a DCC SEND with a single long argument, or (2) a DCC SEND with IP, port, and filesize arguments with a 0 value. |
| 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. |
| 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 WRT54GS and BEFW11S4 allows remote attackers to cause a denial of service (device crash) via an IP packet with the same source and destination IPs and ports, and with the SYN flag set (aka LAND). NOTE: the provenance of this issue is unknown; the details are obtained solely from the BID. |
| 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. |
| 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. |
| Linksys WRT54G v4.21.5 has a stack overflow vulnerability in get_merge_mac function. |
| A vulnerability was found in Linksys WRT54GL 4.30.18 and classified as problematic. Affected by this issue is some unknown functionality of the file /SysInfo.htm of the component Web Management Interface. The manipulation leads to information disclosure. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-253328. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. |
| A vulnerability was found in Linksys WRT54GL 4.30.18. It has been classified as problematic. This affects an unknown part of the file /wlaninfo.htm of the component Web Management Interface. The manipulation leads to information disclosure. The exploit has been disclosed to the public and may be used. The identifier VDB-253329 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. |
| 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. |
| The UPnP IGD implementation on the Cisco Linksys WRT54GX with firmware 2.00.05, when UPnP is enabled, configures the SOAP server to listen on the WAN port, which allows remote attackers to administer the firewall via SOAP requests. |
| A buffer overflow vulnerability exists in Linksys WRT54GL Wireless-G Broadband Router with firmware <= 4.30.18.006. A stack-based buffer overflow in the Start_EPI function within the httpd binary allows an authenticated attacker with administrator privileges to execute arbitrary commands on the underlying Linux operating system as root. This vulnerablity can be triggered over the network via a malicious POST request to /apply.cgi. |
| A null pointer dereference vulnerability exists in Linksys WRT54GL Wireless-G Broadband Router with firmware <= 4.30.18.006. A null pointer dereference in the soap_action function within the upnp binary can be triggered by an unauthenticated attacker via a malicious POST request invoking the AddPortMapping action. |
| An arbitrary code execution vulnerability exisits in Linksys WRT54GL Wireless-G Broadband Router with firmware <= 4.30.18.006. The Check_TSSI function within the httpd binary uses unvalidated user input in the construction of a system command. An authenticated attacker with administrator privileges can leverage this vulnerability over the network via a malicious POST request to /apply.cgi to execute arbitrary commands on the underlying Linux operating system as root. |
