CVE-2012-2983 is an arbitrary file read vulnerability in file/edit_html.cgi in Webmin 1.590 and earlier. The CGI script does not perform a required authorization check before displaying a file's unedited contents. An attacker can supply a crafted file parameter to cause the application to return the contents of arbitrary files. Available context also characterizes the issue as a directory traversal flaw that allows viewing any file as user root, indicating the file access is not properly restricted to an intended directory or authorized resource set.

This repository contains a single Metasploit auxiliary module targeting a directory traversal vulnerability in Webmin 1.580 (CVE-2012-2983). The exploit abuses the 'file' parameter in the edit_html.cgi component, allowing an authenticated user with access to the File Manager module to read arbitrary files on the server with root privileges. The module first authenticates to Webmin using provided credentials, then crafts a traversal path to the desired file (default: /etc/shadow) and sends a request to retrieve its contents. The exploit is operational, requiring valid credentials, and is implemented in Ruby as part of the Metasploit framework. The main endpoints involved are /session_login.cgi for authentication and /file/edit_html.cgi for the file read operation. The repository is structured as a single Ruby file under the Metasploit modules/auxiliary/admin/webmin directory.
