Descriptions
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 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.
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.
