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.

→Monitor POST requests to /setup.cgi containing shell metacharacters or command separators in the TimeToLive parameter (e.g., ;, |, &&, backticks). ↗
→This is a blind OS command injection — no output is returned. Detect exploitation attempts by monitoring for unexpected outbound ICMP (ping) traffic from the router to external hosts, which may indicate attacker testing. ↗
→Flag authentication attempts using default credentials admin/admin or admin/password against the router web interface prior to exploitation. ↗
→Scope detection to Netgear DGN1000B devices running firmware versions 1.1.00.24 and 1.1.00.45. ↗

·Exploitation requires prior authentication; attackers must first obtain valid credentials (e.g., via default credentials) before injecting commands. ↗
·The injection is blind — no command output is returned to the attacker, making detection via response-based signatures ineffective. Side-channel indicators (e.g., outbound connections, ICMP) must be used. ↗
