Description

Webmin contains a flaw that allows a remote attacker to traverse outside of a restricted path. The issue is due to the edit_html.cgi script not properly sanitizing user input, specifically directory traversal style attacks (e.g., ../../) supplied via the 'file' parameter. This directory traversal attack would allow the attacker to gain access to arbitrary files.
