Schneider Electric APC Network Management Card Default Login Scanner

The Schneider Electric APC Network Management Card is commonly used in various IT environments for managing and monitoring network-based APC devices. This card is often found in data centers, corporate networks, and remote site facilities where APC UPS systems are utilized. The Network Management Card allows administrators remote access to the UPS, providing them with real-time monitoring data and control over power management functions. This access is crucial for ensuring uptime and maintaining the integrity of power systems in critical infrastructure. Typically, systems administrators and IT support staff use these cards to effectively manage their power infrastructure. The card's web interface complements its utility, providing an easy-to-use portal for power system oversight and control.

The vulnerability detected in this scanner pertains to the use of default login credentials on the Schneider Electric APC Network Management Card. Default credentials pose a significant security risk as they can be exploited by unauthorized users to gain unauthorized access. This detection identifies instances where default usernames and passwords are still in use, which compromise the security posture of the affected systems. When unauthorized access is gained, it may lead to misuse of network resources, data leakage, or system modifications. Consequently, maintaining security best practices by regularly updating credentials is vital to prevent unauthorized access. Swift detection of such vulnerabilities allows for timely remediation, minimizing potential security breaches.

This scanner specifically targets the login endpoint of the Network Management Card to identify the use of default credentials. Through careful analysis of login requests and responses, it checks for successful authentication using common default usernames such as "apc" and "admin." The scanner utilizes a 'pitchfork' attack method for payload delivery, ensuring multiple combinations of usernames and passwords are tested. Regular expression matching is leveraged to analyze response headers for successful login indicators such as redirects and session cookies. Utilized matchers include regex and status code matchers, focusing on indicating successful access attempts. This level of detail ensures that systems are accurately assessed for potential default login vulnerabilities.

If exploited, the default login vulnerability might allow unauthorized access to the UPS management interface, leading to several potential negative outcomes. An attacker could alter configuration settings, disrupting network management functions, or shut down power management systems, potentially causing hardware damage or data loss. Additionally, the vulnerability could be used as a pivot point for further attacks within the network, increasing the risk of widespread compromise. It could also result in unauthorized monitoring of power usage statistics, providing an attacker insights into potential system weaknesses. The overall impact of such unauthorized access can greatly affect business continuity and system reliability.
