Netis Routers Face Serious Authentication and RCE Vulnerabilities
Netis Router Vulnerabilities: Critical Security Flaws Exposed
Recent findings have revealed significant firmware vulnerabilities in multiple Netis router models, including the NX10, NC65, NC63, NC21, and MW5360. These flaws could lead to sensitive information disclosure, authentication bypass, and remote code execution (RCE). The primary vulnerability report, published by cybersecurity researcher h00die-gr3y on GitHub, highlights the urgent need for users to address these security risks, as no fixes have been announced by Netis at this time.
Understanding the Vulnerabilities
The vulnerabilities affecting Netis routers include:
- CVE-2024-48456: This RCE vulnerability allows an authenticated attacker to hijack the admin password reset feature, enabling them to run arbitrary code from an attacker-controlled server.
- CVE-2024-48457: This flaw permits unauthenticated attackers to remotely set the admin password, which can be exploited to gain administrative access.
- CVE-2024-48455: This vulnerability allows attackers to send simple POST requests to the router to retrieve sensitive information, potentially aiding future attacks.
How the Vulnerabilities Work
The vulnerabilities can be exploited in a chain, making them particularly dangerous:
- An attacker can use CVE-2024-48457 to reset the router’s admin password without authentication.
- Once they have admin access, they can exploit CVE-2024-48456 to execute malicious code via the router’s web interface.
- CVE-2024-48455 could provide further sensitive information that could be leveraged in subsequent attacks.
This combination of vulnerabilities poses a serious risk to users, especially since the flawed password reset systems enable easy authentication bypass.
Impact on Users
The implications of these vulnerabilities are significant. Routers like those sold by Netis can be hijacked to form botnets, which are then used to launch larger-scale cyberattacks. For instance, similar devices were previously implicated in a Mirai botnet-based DDoS attack in October 2023.
What You Should Do
If you own a Netis router, consider the following actions to safeguard your network:
- Update Firmware: Regularly check for firmware updates from Netis, even though no fixes are currently available for these vulnerabilities.
- Change Default Passwords: Ensure that any default passwords are changed to strong, unique credentials.
- Monitor Network Activity: Keep an eye on unusual activity within your network to catch any unauthorized access early.
