ManageEngine NetFlow Analyzer Default Login Scanner

ManageEngine Netflow Analyzer is used by organizations to monitor and analyze network traffic details and performance. It's commonly deployed in IT environments for real-time visibility into network statistics and to detect anomalies. Network administrators utilize this software to ensure efficient use of bandwidth and diagnose network issues. The software typically benefits industries that require large-scale data management and precise network analysis. As it oversees comprehensive metrics and trends in data transmission, it's widely considered vital for both large-scale enterprises and small businesses aiming to optimize their networking environments. Users appreciate its detailed reporting capabilities that help with audit and compliance requirements.

The vulnerability in question is related to the software's default login credentials, which might be left unchanged by users post-installation. This issue falls under security misconfiguration, as default or weak passwords can provide easy access for unauthorized users. An adversary exploiting this vulnerability could gain administrative access to the software. Once inside, the attacker could manipulate network traffic data, erase logs, or perform malicious activities. Identifying this specific vulnerability is crucial because it makes the software susceptible to unauthorized access, potentially leading to network compromise.

Technically, this vulnerability exists because the default username and password ('admin', 'admin') may remain unchanged in some systems. The vulnerable endpoints, such as the login interface marked as '/netflow/jspui/j_security_check', are pivotal in this scenario. By targeting the login page, attackers submit credentials to exploit systems with poorly managed user accounts. The issue could involve the software’s HTTP session management exposing cookies, like 'NFA_Jsession=' or 'JSESSIONID'. The overlooked security practice of changing default credentials immediately upon installation allows unauthorized parties to exploit this vulnerability easily.

Exploiting this vulnerability can lead to unauthorized access to sensitive organizational data processed by the Netflow Analyzer. Attackers may access configuration settings, manipulate logged data, and potentially disrupt operations by altering network monitoring configurations. Such access enables them to perform further network intrusions, burrow through the system unnoticed, and employ techniques to remain persistent within the network. These actions can also lead to data breaches, financial losses, and reputational damage to the organization. The altered configurations might further conceal the attacker's subsequent activities, making this vulnerability's exploitation highly detrimental.
