Kedacom Network Keyboard Console Arbitrary File Read Scanner

The Kedacom Network Keyboard Console is used in various industries to facilitate the operation and management of network systems. It provides users with a physical interface to interact with network components, often in security and traffic management applications. The console is widely utilized by network administrators to configure and monitor network devices in real-time. Kedacom products are known for their integration in large-scale networking environments, particularly in areas needing robust security measures. The network keyboard console aids in optimizing workflow and maintaining seamless communication between network nodes. Its design emphasizes reliability and ease of use, making it a preferred choice for many professionals overseeing complex network structures.

The vulnerability detected in the Kedacom Network Keyboard Console is a Local File Inclusion (LFI) vulnerability. LFI vulnerabilities occur when an application constructs a file path using untrusted input, which leads to unexpected inclusion of files residing on the server. This enables attackers to read sensitive files and data from the server's file system. LFI can lead to more severe exploits if attackers manage to gain control over server execution. It arises from improper validation of user-supplied input in file paths. Exploiting this flaw can expose critical configuration files, user data, credentials, and other sensitive information stored within the system.

The technical details of this vulnerability involve crafting specific GET requests that manipulate file paths. The vulnerability is triggered by appending a traversal path such as "../../../../../../../../etc/passwd" to a base URL, allowing access to files beyond the intended directory scope. This demonstrates inadequate sanitization of path inputs in the web server's file handling mechanisms. The presence of path traversal characters combined with sensitive file names forms a potent vector for exploitation. A successful attack confirms the presence of the target system's sensitive files when the server returns readable contents. This vulnerability primarily hinges on the application's acceptance of unvalidated path inputs within its console interface endpoint.

The possible effects of exploiting this vulnerability include unauthorized access to sensitive files on the server hosting the Kedacom Network Keyboard Console. Attackers may retrieve critical system files, including configuration files and password files, compromising the integrity and confidentiality of the network environment. The exploitation of this LFI could further pave the way for additional, more severe attacks such as remote code execution, especially if log files or files writable by the web server are accessible. It may jeopardize the organization's data security, potentially leading to data breaches or operational disruptions. Moreover, malicious users could leverage this flaw to gain elevated privileges within the network infrastructure.
