Description
An authenticated OS command injection vulnerability exists in Netgear routers (tested on the DGN1000B model firmware versions 1.1.00.24 and 1.1.00.45) via the TimeToLive parameter in the setup.cgi endpoint. The vulnerability arises from improper input neutralization, enabling command injection through crafted POST requests. This flaw enables remote attackers to deploy payloads or manipulate system state post-authentication.
