VAR-201810-1092
Vulnerability from variot - Updated: 2023-12-18 13:13Devices 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
