Newcapec Remote Code Execution Scanner

Newcapec is used by various organizations primarily in educational institutions for managing front-end service operations. It is designed to streamline administrative tasks, facilitate communication, and provide essential services to students and faculty. The platform's services include course management, student information systems, and campus notifications. Educational entities that seek efficient digital management solutions often employ Newcapec to enhance their service delivery. By integrating various functionalities in a single interface, Newcapec aims to offer comprehensive support for a variety of institutional needs. Its widespread application in educational settings makes it a critical component in many organizations' IT infrastructures.

The Remote Code Execution vulnerability identified in Newcapec allows unauthorized users to execute arbitrary commands on the server. This type of vulnerability is severe as it could lead to complete control of the affected system by an attacker. The vulnerability is present in the service action interface, which does not adequately validate user inputs or commands. Exploiting this flaw, attackers can remotely inject and execute code, potentially compromising sensitive data. Such vulnerabilities highlight the vital need for stringent security measures and robust input validation within the system. With proper exploitation, attackers can exploit these weaknesses to disrupt or manipulate system operations maliciously.

The technical details of this vulnerability involve a flaw in the service.action interface. The vulnerability is linked to the application's inability to properly manage and sanitize input commands. The template's endpoint leverages FreeMarker template injections to run arbitrary commands, which can be reflected in the server's output files. Endpoints such as /service_transport/service.action are at risk due to improper command management. Parameters within HTTP POST requests can be manipulated to execute code on the server through unsanitized input handling. Supported by evidence from server responses, the vulnerability facilitates the writing of arbitrary data to server-side text files.

When exploited, this vulnerability can have grave consequences including unauthorized access, data theft, and system manipulation. Attackers could gain control over the server, leading to potential system crashes or service outages. Data integrity and confidentiality could be compromised, resulting in the leakage of sensitive information. The attacker might also deploy backdoors, maintaining persistent access to the system for future exploits. Such exploitation may also disrupt institutional workflows, affecting educational service delivery. Furthermore, it might incur financial losses due to breach mitigation costs and loss of reputation.
