Netentsec NS-ICG Default Login Scanner

The Netentsec NS-ICG is a robust application security gateway utilized by organizations to protect their networks from unauthorized access, data breaches, and cyber threats. This gateway is mainly employed by IT departments, cybersecurity firms, and network administrators to maintain a secure environment. Its features include traffic filtering, user authentication, and session management, ensuring safety for digital assets. The NS-ICG operates in various industries, including finance and healthcare, where data protection is crucial. Its ease of use and integration capabilities make it a suitable choice for businesses of different sizes. Regular updates and a supportive vendor ensure that it meets evolving cybersecurity needs.

The default login vulnerability in the Netentsec NS-ICG can allow unauthorized users to gain access to the system using factory default credentials often left unchanged. This type of vulnerability is prevalent in systems with standardized login setups. If exploited, it can result in unauthorized access, data tampering, and exposure of sensitive information. Security misconfigurations such as these are often targeted by attackers looking for easy entry points. Often, users overlook the necessity of password changes post-installation, leaving systems vulnerable. Recognizing and mitigating this vulnerability is essential in maintaining a secure network environment.

Technical details of the default login vulnerability include using the default credentials provided by the manufacturer, which are typically 'ns25000' for both username and password. The vulnerable endpoint in this case is the '/user/login/login' URL where these credentials can be submitted. Successful login grants access to '/user/main' which confirms the vulnerability. Attackers can exploit this by making a POST request with the default credentials to gain administrative privileges. Additionally, a GET request to '/user/main' can be used after a successful POST to verify access. The detection method proves successful when specific status codes and response indicators are returned.

Exploiting the default login vulnerability on the NS-ICG can lead to severe consequences. Malicious actors can gain administrative access, allowing them to alter configurations and compromise network security. This can result in data breaches, loss of sensitive information, and the potential for further exploitation of the network. Organizations may face downtime, reputational damage, and compliance issues as a result of such an exploit. Furthermore, recovery from such incidents can be costly and time-consuming, underscoring the critical nature of addressing this vulnerability promptly.
