Netgear WNR614 Improper Access Control Scanner

Netgear WNR614 is a widely used wireless router designed for home and small office networks. It is utilized by individuals and businesses for its affordable price point and reliable performance. This router facilitates Wi-Fi connectivity for multiple devices, allowing seamless internet access for users. Typically, this product is preferred by users seeking a cost-effective networking solution. Its ease of setup and user-friendly interface make it a popular choice among non-technical users. Given its widespread adoption, identifying and mitigating vulnerabilities in this product is crucial to maintain network security.

Improper Access Control is a vulnerability where unauthorized individuals are capable of bypassing authentication mechanisms. This specific vulnerability in the Netgear WNR614 permits attackers to exploit improper authentication processes. By appending particular strings to the URL, unauthorized access to configuration settings can be achieved. This flaw arises when the router incorrectly processes and validates URL inputs. The absence of stringent security checks allows attackers to exploit this vulnerability with minimal effort. Detecting this vulnerability is essential to prevent unauthorized access to network configurations.

The technical core of this vulnerability lies in the improper URL handling of the Netgear WNR614 router. By adding "%%%%00currentsetting.htm" to the requested URL, the router erroneously processes it as an authenticated request. This allows intruders to access sensitive configuration pages without valid credentials. The endpoint affected is primarily the configuration settings page, where sensitive information may be displayed. The vulnerability is a result of deficient input validation and improper authentication mechanisms. This issue could potentially expose the root of the router's security framework if not corrected.

If exploited, malicious actors can gain unauthorized access to the router’s administrative settings. This can lead to potential mishandling or manipulation of network configurations, weakening the overall security posture. Attackers may intercept or change the network settings, affecting the integrity and confidentiality of communications. Unauthorized access to the router could also pave the way for further intrusions into connected systems. The vulnerability can expose sensitive network information, making it susceptible to additional attacks, including eavesdropping.
