Summary
by MITRE • 08/02/2025
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.

This vulnerability represents a critical authenticated OS command injection flaw in Netgear DGN1000B routers, specifically affecting firmware versions 1.1.00.24 and 1.1.00.45. The issue manifests through the TimeToLive parameter within the setup.cgi web endpoint, where inadequate input validation allows maliciously crafted POST requests to execute arbitrary operating system commands. The vulnerability stems from improper input neutralization techniques that fail to adequately sanitize user-supplied data before processing, creating a pathway for attackers to inject malicious commands into the underlying operating system. This authentication requirement means that an attacker must first establish valid credentials to exploit the vulnerability, though the impact remains significant once accessed.
The technical implementation of this flaw demonstrates a classic command injection vulnerability that aligns with CWE-77 standards, specifically categorized under improper neutralization of special elements used in OS commands. The vulnerability operates through the web interface's handling of the TimeToLive parameter, where user input directly influences system command execution without proper sanitization or escaping mechanisms. Attackers can construct malicious payloads that, when submitted through the setup.cgi endpoint, are processed by the router's operating system, potentially enabling complete system compromise. The authenticated nature of this vulnerability places it within the ATT&CK framework under T1059.001 for Command and Scripting Interpreter, with potential lateral movement capabilities once initial access is established.
The operational impact of this vulnerability extends beyond simple command execution, as it enables attackers to manipulate the router's system state and deploy persistent payloads. An attacker with valid authentication credentials could potentially gain root access to the router's operating system, allowing for complete network compromise and the ability to modify firewall rules, DNS settings, or establish backdoor access points. The vulnerability affects the router's core network functionality and could enable man-in-the-middle attacks, traffic interception, or complete network disruption. This type of vulnerability represents a significant risk to home and small office networks where router security is often overlooked, as it provides attackers with a persistent foothold that can be used for extended periods without detection.
Mitigation strategies for this vulnerability require immediate firmware updates from Netgear to address the input validation flaws in the setup.cgi endpoint. Network administrators should ensure that all affected devices are updated to patched firmware versions that properly sanitize the TimeToLive parameter and other input fields. Additional protective measures include implementing network segmentation to limit access to router management interfaces, enforcing strong authentication practices, and monitoring for unusual network traffic patterns that might indicate exploitation attempts. The vulnerability highlights the importance of proper input validation and output encoding in web applications, particularly those interfacing with operating system commands, as outlined in OWASP Top Ten and NIST guidelines for secure coding practices. Organizations should also consider implementing intrusion detection systems to monitor for known exploitation patterns and maintain comprehensive network monitoring to detect potential compromise indicators.
