Authenticated OS Command Injection in Netgear DGN1000B setup.cgi TimeToLive Parameter

IdentifiersCVE-2013-10061CWE-78· Improper Neutralization of Special…

CVE-2013-10061 is an authenticated OS command injection vulnerability in Netgear routers, confirmed on the DGN1000B model running firmware versions 1.1.00.24 and 1.1.00.45. The flaw is exposed through the setup.cgi endpoint, specifically via the TimeToLive POST parameter. The issue results from improper neutralization of attacker-controlled input before it is incorporated into an operating system command, allowing a crafted authenticated request to inject and execute arbitrary shell commands on the device. Based on the available information, exploitation occurs remotely after authentication and can be used to deploy payloads or alter router state.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an authenticated remote attacker to execute arbitrary operating system commands in the context of the vulnerable router. This can enable deployment of additional payloads, modification of device configuration or system state, and potentially full compromise of the affected device depending on the privileges of the underlying process handling setup.cgi. The vulnerability may also be leveraged to establish persistence, manipulate network behavior, or disrupt normal router operation.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to the router administrative interface so that setup.cgi is not reachable from untrusted networks. Disable remote administration if not required, and limit management access to a dedicated internal management network or specific trusted IP addresses. Enforce strong unique administrator credentials to reduce the likelihood of authenticated exploitation. Monitor for unexpected POST requests to setup.cgi and suspicious configuration changes. Where feasible, place the device behind additional network controls and plan hardware replacement if the product is end-of-life or unsupported.

Remediation

Patch, then assume compromise.

Upgrade affected Netgear DGN1000B devices to a fixed firmware version if one is available from the vendor. If no patched firmware is available, replace affected devices with supported hardware. Review vendor security advisories and release notes to identify corrected builds for the setup.cgi command injection issue. Because the flaw is in server-side input handling for the TimeToLive parameter, remediation requires vendor code changes or firmware replacement rather than configuration-only changes.

netgear_dgn1000b_setup_exec.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module targeting Netgear DGN1000B routers (and potentially similar models) vulnerable to authenticated OS command injection (CVE-2013-10061) in the web interface's setup.cgi endpoint. The exploit requires valid credentials (default: admin/admin or admin/password) and network access to the device's HTTP interface. The module works by injecting commands into the TimeToLive parameter of a POST request to /setup.cgi. It supports two payload types: direct command execution (CMD) and deployment of a MIPS ELF binary (e.g., a reverse shell), which is served via an HTTP server started by the module. The payload is downloaded to /tmp/<random_filename> on the device, made executable, and then run. The module is operational and provides remote code execution as root on the target device. The code is written in Ruby and is structured as a standard Metasploit exploit module.
