- 漏洞描述

BearShare contains a flaw that allows a remote user to traverse outside of a restricted path. The issue is due to the application not properly sanitizing user input, specifically directory traversal style attacks (e.g., ../../) using hexadecimal URL encoded forward-slash characters supplied via the URI parameter. This directory traversal attack would allow the attacker to view files outside of the web root directory.
