受影响系统:
RaidenHTTPD Server 1.1.49
描述:
BUGTRAQ ID: 19918
RaidenHTTPD Server是Windows 98/Me/2000/XP/2003平台上具有完全特性的Web server软件,用户可以方便的使用和安装。
RaidenHTTPD自带的脚本在处理用户请求时存在输入验证漏洞,远程攻击者可能利用此漏洞在服务器上以Web进程权限执行任意命令。
RaidenHTTPD的raidenhttpd-admin/slice/check.php脚本没有正确验证SoftParserFileXml参数的输入,允许攻击者通过包含本地或外部资源的文件执行任意PHP代码。成功攻击要求启用了WebAdmin功能。

explanaition: this software carries a PHP interpreter (4.4.1 version...) and you have an administrative interface in /raidenhttpd-admin folder but... you can have anauthorized access to some scripts in /raidenhttpd-admin/slice folder, in check.php at line 35 u have:
... include_once($SoftParserFileXml); // This is the parser class. ...
$SoftParserFileXml var is not initizialized so u can include an arbitrary uploaded temporary file or arbitrary http location
also register_globals and allow_url_fopen are enabled by default (harakiri?)
