Description

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