| 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. |
| 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. |
| 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. |
| 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. |
| 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 WET11 1.5.4 allows remote attackers to change the password without providing the original password via the data parameter to changepw.html. |
| 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. |
| 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 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 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. |
| A directory traversal vulnerability exists in Linksys router's web interface (tested on the E1500 model firmware versions 1.0.00, 1.0.04, and 1.0.05), specifically in the /apply.cgi endpoint. Authenticated attackers can exploit the next_page POST parameter to access arbitrary files outside the intended web root by injecting traversal sequences. This allows exposure of sensitive system files and configuration data. |
| Linksys E1000 devices through 2.1.02, E1200 devices before 2.0.05, and E3200 devices through 1.0.04 allow OS command injection via shell metacharacters in the apply.cgi ping_ip parameter on TCP port 52000. |
| An authenticated OS command injection vulnerability exists in various Linksys router models (tested on WRT160Nv2) running firmware version v2.0.03 via the apply.cgi endpoint. The web interface fails to properly sanitize user-supplied input passed to the ping_size parameter during diagnostic operations. An attacker with valid credentials can inject arbitrary shell commands, enabling remote code execution. |
| A stack-based buffer overflow vulnerability exists in the tmUnblock.cgi endpoint of the Linksys WRT120N wireless router. The vulnerability is triggered by sending a specially crafted HTTP POST request with an overly long TM_Block_URL parameter to the endpoint. By exploiting this flaw, an unauthenticated remote attacker can overwrite memory in a controlled manner, enabling them to temporarily reset the administrator password of the device to a blank value. This grants unauthorized access to the router’s web management interface without requiring valid credentials. |
| A vulnerability, which was classified as critical, was found in Linksys E8450 up to 1.2.00.360516. This affects the function set_device_language of the file portal.cgi of the component HTTP POST Request Handler. The manipulation of the argument dut_language leads to buffer overflow. It is possible to initiate the attack 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. |
| An OS command injection vulnerability exists in various models of E-Series Linksys routers via the /tmUnblock.cgi and /hndUnblock.cgi endpoints over HTTP on port 8080. The CGI scripts improperly process user-supplied input passed to the ttcp_ip parameter without sanitization, allowing unauthenticated attackers to inject shell commands. This vulnerability was reported to be exploited in the wild by the "TheMoon" worm in 2014 to deploy a MIPS ELF payload, enabling arbitrary code execution on the router. Additionally, this vulnerability may affect other Linksys products to include, but not limited to, WAG/WAP/WES/WET/WRT-series router models and Wireless-N access points and routers. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC. |
| A vulnerability has been found in Linksys WRT1900ACS, EA7200, EA7450 and EA7500 up to 20250619 and classified as critical. This vulnerability affects the function SetDefaultConnectionService of the file /upnp/control/Layer3Forwarding of the component IGD. The manipulation of the argument NewDefaultConnectionService leads to stack-based buffer overflow. The attack can be initiated 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. |
| A stack-based buffer overflow exists in the get_merge_ipaddr function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The function concatenates up to four user-supplied CGI parameters matching <parameter>_0~3 into a fixed-size buffer (a2) without bounds checking. Remote attackers can exploit this vulnerability via specially crafted HTTP requests to execute arbitrary code or cause denial of service without authentication. |
| Linksys E5600 V1.1.0.26 is vulnerable to command injection in the runtime.macClone function via the mc.ip parameter. |
| linksys E5600 V1.1.0.26 is vulnerable to command injection in the function ddnsStatus. |
