Executive Summary

CVE-2025-27906 is a Local File Inclusion (LFI) vulnerability in IBM Content Navigator versions 3.0.11, 3.0.15, 3.1.0, and 3.2.0. It allows an attacker to manipulate the application URL to expose the directory listing of the application on the server. This means the attacker can see the files and folders of the application through a browser, but cannot read, obtain, or modify the contents of those files. [1]

Impact Analysis

This vulnerability can expose the directory structure of the IBM Content Navigator application to an attacker without requiring authentication or user interaction. While the attacker cannot read or modify file contents, the exposure of directory listings can provide useful information for further attacks or reconnaissance, potentially increasing the risk to the system.

Detection Guidance

This vulnerability can be detected by attempting to access the application URL of IBM Content Navigator versions 3.0.11, 3.0.15, 3.1.0, or 3.2.0 and checking if the directory listing is exposed in the browser. Since the vulnerability involves directory listing exposure via HTTP(S) requests, you can use tools like curl or wget to send requests to the application URL and observe if directory contents are returned. For example, a command like 'curl -I http://<target>/path/' or 'curl http://<target>/path/' can be used to check for directory listings. However, no specific detection commands are provided in the resources. [1]
