CVE-2024-30570 Scanner

Netgear R6850 Router is a wireless networking device widely used for home and small office internet connectivity. Developed by Netgear, the router provides high-speed internet access with dual-band Wi-Fi and multiple security features. It is commonly used by consumers and small businesses to manage network connections efficiently. The device includes a web-based management interface that allows users to configure settings and monitor network traffic. Netgear routers are known for their reliability and ease of use, making them popular among non-technical users. Regular firmware updates are essential to ensure security and performance.

The vulnerability found in the Netgear R6850 Router is an Information Disclosure flaw. It affects firmware version V1.1.0.88 and allows unauthorized access to sensitive information. The issue stems from the debuginfo.htm page, which lacks authentication, exposing data such as WAN connection type and product model name. Attackers can leverage this flaw to gather critical network details that may aid in further exploitation. Since the page is publicly accessible, any remote attacker can retrieve this information. The vulnerability poses a risk to users who have not restricted access to the router’s web interface.

The root cause of the vulnerability is the improper access control on the debuginfo.htm page. This page is accessible without authentication, meaning any attacker with network access can retrieve sensitive data. The exposed details can include network configuration settings and internal system information. Attackers may use automated tools to scan for vulnerable devices and extract information. The lack of access restrictions makes it easier for threat actors to exploit the flaw without requiring credentials. Fixing this issue requires implementing authentication controls on the affected page.

If exploited, this vulnerability can lead to significant security risks. Attackers may use the disclosed information to plan more advanced attacks, such as gaining unauthorized access to the network. Information like WAN connection type can help attackers identify network configurations and potential weaknesses. Exposing system details may also allow attackers to craft targeted exploits against the router. Additionally, in certain scenarios, leaked data could aid in credential-based attacks or brute force attempts. Users who leave their router’s web interface exposed to the internet are at higher risk.
