VAR-202511-1036
Vulnerability from variot - Updated: 2025-12-19 22:57An unauthenticated command injection vulnerability exists in the Start_EPI function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The vulnerability occurs because user-supplied CGI parameters (wl_ant, wl_ssid, wl_rate, ttcp_num, ttcp_ip, ttcp_size) are concatenated into system command strings without proper sanitization and executed via wl_exec_cmd. Successful exploitation allows remote attackers to execute arbitrary commands on the device without authentication. The Linksys E1200 is a router manufactured by Linksys, Inc

VAR-202511-0715
Vulnerability from variot - Updated: 2025-12-19 19:39A 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 _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. The Linksys E1200 is a router manufactured by Linksys, Inc

VAR-202511-0548
Vulnerability from variot - Updated: 2025-11-22 23:30A stack-based buffer overflow exists in the httpd binary of Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The apply_cgi and block_cgi functions copy user-supplied input from the "url" CGI parameter into stack buffers (v36, v29) using sprintf without bounds checking. Because these buffers are allocated as single-byte variables, any non-empty input will trigger a buffer overflow. Remote attackers can exploit this vulnerability via crafted HTTP requests to execute arbitrary code or cause denial of service without authentication. (DoS) It may be in a state

VAR-202511-1199
Vulnerability from variot - Updated: 2025-11-22 23:26A stack-based buffer overflow vulnerability exists in the libshared.so library of Cisco Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The functions get_mac_from_ip and get_ip_from_mac use sscanf with overly permissive "%100s" format specifiers to parse entries from /proc/net/arp into fixed-size buffers (v6: 50 bytes, v7 sub-arrays: 50 bytes). This allows local attackers controlling the contents of /proc/net/arp to overflow stack buffers, leading to memory corruption, denial of service, or potential arbitrary code execution. (DoS) It may be in a state

VAR-202511-0383
Vulnerability from variot - Updated: 2025-11-22 23:19A stack-based buffer overflow exists in the validate_static_route function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The function improperly concatenates user-supplied CGI parameters (route_ipaddr_0~3, route_netmask_0~3, route_gateway_0~3) into fixed-size buffers (v6, v10, v14) without proper bounds checking. Remote attackers can exploit this vulnerability via specially crafted HTTP requests to execute arbitrary code or cause denial of service without authentication

VAR-202511-0870
Vulnerability from variot - Updated: 2025-11-19 23:32A stack-based buffer overflow exists in the get_merge_mac function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The function concatenates up to six user-supplied CGI parameters matching _0~5 into a fixed-size buffer (a2) without proper bounds checking, appending colon delimiters during concatenation. Remote attackers can exploit this vulnerability via specially crafted HTTP requests to execute arbitrary code or cause denial of service without authentication.

VAR-201810-1093
Vulnerability from variot - Updated: 2024-11-23 22:21An exploitable operating system command injection exists in the Linksys ESeries line of routers (Linksys E1200 Firmware Version 2.0.09 and Linksys E2500 Firmware Version 3.0.04). Specially crafted entries to network configuration information can cause execution of arbitrary system commands, resulting in full control of the device. An attacker can send an authenticated HTTP request to trigger this vulnerability. Data entered into the 'Domain Name' input field through the web portal is submitted to apply.cgi as the value to the 'wan_domain' POST parameter. The wan_domain data goes through the nvram_set process described above. When the 'preinit' binary receives the SIGHUP signal it enters a code path that calls a function named 'set_host_domain_name' from its libshared.so shared object. The BelkinLinksys E1200 and E2500 are both E-series wireless router products from Belkin

VAR-201810-1148
Vulnerability from variot - Updated: 2024-11-23 22:21Devices in the Linksys ESeries line of routers (Linksys E1200 Firmware Version 2.0.09 and Linksys E2500 Firmware Version 3.0.04) are susceptible to OS command injection vulnerabilities due to improper filtering of data passed to and retrieved from NVRAM. Data entered into the 'Router Name' input field through the web portal is submitted to apply.cgi as the value to the 'machine_name' POST parameter. When the 'preinit' binary receives the SIGHUP signal, it enters a code path that continues until it reaches offset 0x0042B5C4 in the 'start_lltd' function. Within the 'start_lltd' function, a 'nvram_get' call is used to obtain the value of the user-controlled 'machine_name' NVRAM entry. This value is then entered directly into a command intended to write the host name to a file and subsequently executed. The BelkinLinksys E1200 and E2500 are both E-series wireless router products from Belkin. An attacker can exploit this vulnerability to execute arbitrary commands on the system by sending a specially crafted request

VAR-201810-1092
Vulnerability from variot - Updated: 2024-11-23 22:21Devices in the Linksys ESeries line of routers (Linksys E1200 Firmware Version 2.0.09 and Linksys E2500 Firmware Version 3.0.04) are susceptible to OS command injection vulnerabilities due to improper filtering of data passed to and retrieved from NVRAMData entered into the 'Router Name' input field through the web portal is submitted to apply.cgi as the value to the 'machine_name' POST parameter. When the 'preinit' binary receives the SIGHUP signal it enters a code path that calls a function named 'set_host_domain_name' from its libshared.so shared object. The BelkinLinksys E1200 and E2500 are both E-series wireless router products from Belkin. An operating system command injection vulnerability exists in the BelkinLinksysE1200 with firmware version 2.0.09 and the LinksysE2500 with firmware version 3.0.04. An attacker can exploit this vulnerability to execute arbitrary commands on the system by sending a specially crafted request
