CVE-2024-57046 Scanner

Netgear DGN2200 is a wireless router widely used in residential and small office environments. It provides high-speed internet connectivity through ADSL broadband services. The device features a web-based management interface for network configuration and security settings. Netgear routers are popular due to their user-friendly design and extensive support from the manufacturer. The DGN2200 model offers firewall capabilities, parental controls, and WPA/WPA2 encryption for security. However, security vulnerabilities in the authentication mechanisms can expose users to unauthorized access risks.

This vulnerability affects the Netgear DGN2200 router and allows attackers to bypass authentication. By appending "?x=1.gif" to a requested URL, an unauthenticated user can gain access to restricted pages. The flaw exists due to improper validation of authentication tokens. Classified under CWE-287 (Improper Authentication), this issue permits unauthorized individuals to bypass access controls. Exploiting this vulnerability may allow attackers to view or modify network settings. This can lead to unauthorized administrative control of the router.

The vulnerability is present in the authentication mechanism of the Netgear DGN2200 router. A standard request to restricted pages returns a 401 Unauthorized response. However, appending "?x=1.gif" to the request enables access, bypassing authentication. This behavior suggests that the router improperly handles specific URL parameters. Attackers can exploit this flaw by crafting requests that manipulate the authentication check. This issue exposes administrative functions to unauthorized access.

Exploitation of this vulnerability can lead to full administrative control of the affected router. Attackers can modify network configurations, change DNS settings, and disable security features. Unauthorized users may also intercept network traffic, leading to data leaks. In a worst-case scenario, attackers could use the compromised router as a pivot point for further attacks. The exposure of network controls significantly increases the risk of cyber threats against connected devices. Users may experience service disruptions, unauthorized surveillance, and data exfiltration.
