CVE-2023-23063 Scanner

Cellinx NVT Web Server is a specialized server software used in various environments, typically within IT and network infrastructure systems, to facilitate data transmission and communication. It is often employed by network administrators and IT professionals to manage traffic and ensure efficient performance of interconnected devices. This server acts as a cornerstone for maintaining data availability and integrity within controlled networks. Users utilize this platform to remotely manage configuration settings and securely access network resources. The software is crucial for seamless operation and robust network communication, ensuring all components function cohesively. Cellinx NVT Web Server provides a pivotal role in ensuring network reliability and operational efficiency.

The Local File Inclusion (LFI) vulnerability detected in Cellinx NVT Web Server can potentially allow unauthorized file access. Typically found in web applications, this vulnerability occurs when the software fails to properly sanitize user inputs. Attackers can exploit this vulnerability to read sensitive files from the server, leading to information disclosure. This vulnerability poses a significant risk to the confidentiality of the system data. Improper file process management leaves the application exposed to exploitation by malicious individuals. Managing LFI vulnerabilities is crucial to maintaining the integrity and confidentiality of your system's data.

The LFI vulnerability in Cellinx NVT Web Server is present via the '/cgi-bin/GetFileContent.cgi' component. This end point allows unauthorized users to read files they should not have access to. The exploit uses a crafted request involving 'USER' and 'PWD' parameters to access system files. Notably, it can disclose sensitive files such as '/etc/passwd', critical for Unix-based systems. The vulnerability exists due to insufficient input validation and improper file path handling. Fixing such vulnerabilities typically requires stringent input checks and access controls, ensuring unauthorized individuals cannot abuse file path parameters.

Exploitation of this vulnerability could lead to significant security breaches, such as unauthorized access to sensitive system files and data leakage. Attackers might gain insights into system configurations, user credentials, or other sensitive information. If not patched, this vulnerability could serve as a stepping stone for more severe attacks, such as privilege escalation or full system compromise. The confidentiality and integrity of the network data could be compromised, leading to potential information disclosure. Addressing such vulnerabilities is essential in preventing unauthorized exploitation and maintaining system security.
