What is CVE-2018-18730?

A buffer overflow issue exists in the web server (httpd) of Tenda's AC series routers, specifically when handling 'startIp' and 'endIp' parameters in POST requests. This vulnerability occurs because values from these parameters are improperly managed by being directly used in a sprintf function, leading to potential overwriting of the function's return address. This flaw could be exploited by an attacker to execute arbitrary code on the device or disrupt its operation, posing significant security risks.
