https://notcve.org/view.php?id=CVE-2018-3953
Devices 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. • https://talosintelligence.com/vulnerability_reports/TALOS-2018-0625 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

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. Los dispositivos de la línea de routers Linksys ESeries (Linksys E1200 con versión del firmware 2.0.09 y Linksys E2500 con versión del firmware 3.0.04) son susceptibles a vulnerabilidades de inyección de comandos del sistema operativo debido al filtrado incorrecto de datos pasados y recuperados desde los datos NVRAM introducidos en el campo de entrada "Router Name" mediante el portal web y enviados a apply.cgi como el valor del parámetro POST "machine_name". Cuando el binario "preinit" recibe la señal SIGHUP, introduce una ruta de código que llama a una función denominada "set_host_domain_name" desde su objeto compartido en libshared.so. • https://talosintelligence.com/vulnerability_reports/TALOS-2018-0625 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

An 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. • https://talosintelligence.com/vulnerability_reports/TALOS-2018-0625 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
