CVE-2024-30569 Scanner

The Netgear R6850 router is widely used in homes and small businesses to provide fast and reliable internet connectivity. It is valued for its ease of use, advanced features for network management, and strong Wi-Fi coverage. The device often serves as a central hub for smart homes, supporting numerous connected devices. Administrators of the Netgear R6850 can manage router settings and monitor network performance through a web interface. Given its widespread deployment, any vulnerabilities can impact a broad user base, making it crucial to maintain the router's firmware updated to safeguard users' data. Due to its popularity, the device's security posture is an attractive target for cyber adversaries.

The detected vulnerability is an Information Disclosure vulnerability in the Netgear R6850 router firmware. It resides in a hidden interface that is not protected by authentication, allowing unauthorized access to potentially sensitive information. This vulnerability could potentially expose data regarding the device's firmware version, model information, and system configuration. The availability of such information without authentication could be leveraged by attackers to facilitate more targeted attacks. As with many similar vulnerabilities, its exploitability increases with the ease of access and the extent of disclosure. Therefore, addressing this vulnerability promptly is critical to maintaining network security.

Technical details of this vulnerability reveal that the currentsetting.htm page in the router's interface lacks proper authentication, which should ideally safeguard sensitive information. The page contains multiple data points, such as firmware details and model identification, revealing key aspects of the router's configuration. Exploiting this issue only requires the attacker to access the said page, with methods like crafted GET requests yielding sensitive information disclosed in the body of the response. The vulnerability does not require any prior authentication, hence can be exploited remotely, increasing its severity level. Matching the output with specific keywords and status responses can confirm the presence of this vulnerability.

Exploiting this vulnerability can have various potential impacts, particularly concerning exposure of the router and network configuration details. Attackers gaining access to this information might use it to craft advanced targeted attacks, potentially leading to broader network infiltration. The absence of authentication provides a low entry barrier, easing unauthorized data retrieval. Overcoming this flaw could prevent unauthorized network access, reduce the risk of advanced persistent threats, and maintain the overall integrity of systems using the router. Therefore, addressing and mitigating this issue is crucial to preserving security against both opportunistic and targeted exploitation attempts.
