CVE-2025-11700 Scanner

N-central is a widely used software solution in the IT management industry. It is predominantly utilized by managed services providers (MSPs) to monitor, manage, and secure IT environments for their clients. Offering a comprehensive suite of features, N-central helps in the automation of routine tasks, ensuring system uptime and reliability. It provides functionalities for patch management, remote monitoring, and network discovery among other IT management needs. Due to its extensive use, N-central plays a pivotal role in IT infrastructure management. Security flaws in such software can significantly impact a large number of systems managed by service providers.

XML External Entities (XXE) Injection is a common vulnerability that can be exploited in XML parsers. It occurs when external entities are allowed within XML documents, which may enable attackers to read sensitive files from the server. The vulnerability can potentially be used to launch internal network attacks and cause denial of service situations. If exploited, XXE can lead to the disclosure of confidential data. This vulnerability represents a risk to the confidentiality and integrity of information managed by the software.

The XXE vulnerability in N-central is primarily due to insufficient validation of external entities within XML input data. The affected end point in this scenario is part of the SOAP-based web service, specifically the ServerMMS and ServerUI components. It exploits the input fields to include hostile XML payloads that the application processes improperly. These payloads might contain references to external resources which the system should not access. The vulnerability manifests when the software processes these external entities without necessary restrictions or validations in place. Attackers can craft malicious input designed to manipulate or retrieve sensitive information from the system.

If the XML External Entities (XXE) Injection is exploited, sensitive information on the server can be disclosed to attackers. This may give cybercriminals access to internal configurations, administrative data, or confidential user information. The exposure could lead to further system compromises or lateral movements within the network. Additionally, depending on the server setup, attackers can exploit XXE to launch more malicious activities such as denial of service attacks or network enumeration. The implications also extend to reputational damage for the affected organizations, especially when sensitive customer data is exposed.
