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?)
