TOTOLINK N150RT Credential Disclosure Scanner

The TOTOLINK N150RT is a wireless router that is used for connecting multiple devices to the internet within a home or small office environment. It is often chosen for its affordability and ease of use, making it a popular option for residential and small business users. The router supports basic networking features necessary for creating a local area network. Network administrators and technically-inclined users configure these routers to manage internet access, secure the network, and maintain connectivity. The device is operated through a web-based interface, allowing users to configure settings via a browser. Users rely on this product to maintain their digital security and manage network traffic efficiently.

A Credential Disclosure vulnerability involves the exposure of sensitive user credentials, often due to misconfigurations or insecure endpoints. It can arise when sensitive data, such as usernames and passwords, are inadvertently made accessible through a web page. This type of vulnerability can severely compromise a network device like the TOTOLINK N150RT router, as unauthorized access to credentials can lead to unauthorized access to network controls. Protecting against such vulnerabilities is crucial to prevent unauthorized access to sensitive configurations and user data. This type of exposure highlights the importance of secure configuration practices in network administration.

The vulnerability in the TOTOLINK N150RT router occurs due to the exposure of sensitive credentials in the password.htm page. The page inadvertently displays fields that contain the original password and username without adequate security measures. Attackers exploiting this vulnerability could access the password page and harvest these credentials by sending an HTTP GET request to the exposed endpoint. The vulnerability check involves matching specific patterns in the response body that include terms like "orgpassword=" and "orgusername=". To confirm the presence of the issue, the scanner ensures these patterns are found while excluding any empty password fields with "orgpassword=''" from consideration.

If exploited, this Credential Disclosure vulnerability can lead to unauthorized access to the router's administrative interface. Malicious users could potentially change the network settings, access connected devices, or disrupt the network service entirely. This exploitation can further lead to a breach of sensitive information stored on other devices in the network. Network integrity may be compromised, and user data confidentiality could be at risk. The security and privacy of users connected to the vulnerable router could be significantly impacted if these credentials fall into the wrong hands.
