CVE-2024-51010 is a command injection vulnerability identified in multiple Netgear router models: R8500 v1.0.2.160, XR300 v1.0.3.78, R7000P v1.3.3.154, and R6400 v2 1.0.4.128. The vulnerability resides in the ap_mode.cgi component, specifically through the apmode_gateway parameter. An attacker with at least low-level privileges and network access can send a specially crafted request to this CGI endpoint, which fails to properly sanitize input, allowing arbitrary operating system commands to be executed. This type of vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command). The CVSS v3.1 score is 8.0, reflecting high severity, with attack vector being adjacent network (AV:A), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation could lead to full compromise of the router, enabling attackers to manipulate network traffic, deploy malware, or pivot to internal networks. No public exploits are known yet, but the vulnerability's nature and affected devices' widespread use make it a significant threat. The lack of available patches at the time of disclosure increases urgency for mitigation.

The impact of CVE-2024-51010 is substantial for organizations using the affected Netgear routers. Successful exploitation allows attackers to execute arbitrary OS commands, potentially leading to complete device compromise. This can result in unauthorized access to internal networks, interception or manipulation of network traffic, disruption of network services, and deployment of persistent malware. Given that routers are critical network infrastructure components, their compromise can undermine the security posture of entire organizations, affecting confidentiality, integrity, and availability of data and services. The vulnerability requires only low privileges and no user interaction, increasing the risk of automated or wormable attacks within local networks. Organizations in sectors relying heavily on these routers for connectivity, including small to medium enterprises, ISPs, and home office environments, face elevated risks. The absence of known exploits currently provides a window for proactive defense, but the threat landscape could rapidly evolve.

To mitigate CVE-2024-51010, organizations should first verify if they are using any of the affected Netgear router models and firmware versions. Since no official patches are currently available, immediate steps include restricting access to the router management interfaces, especially the ap_mode.cgi endpoint, by implementing network segmentation and firewall rules to limit access to trusted administrators only. Disable remote management features if enabled. Monitor network traffic for unusual requests targeting the apmode_gateway parameter. Employ intrusion detection/prevention systems (IDS/IPS) with signatures tuned to detect command injection attempts. Regularly check Netgear’s official channels for firmware updates addressing this vulnerability and apply them promptly once released. Additionally, consider replacing vulnerable devices with models confirmed to be secure if patching is delayed. Educate network administrators about the risks and signs of exploitation to enable rapid incident response.
