你想逆推？去看看有没有什么工具吧。

其实没有必要研究这，倒是应该逐页面的检查一下系统哪一块有漏洞，没对用户提交的数据进行过滤。

这个代码是OA系统上的一个关键文件，好像处理都在该文件中进行
我想明白下，这段代码是什么意思，然后好对这个OA系统进行修改

人家的收费程序？自己一个一个的逆吧.不是分的事，是太耗时间了,而且还学不到什么新鲜东西...

死了心吧

呵呵收费程序伤不起啊。

这个也不难

define('IN_ADMIN',True);require_once('include/common.php');include('include/excel_writer.class.php');if (GET_INC_CONFIG_INFO("opendate")关闭原因：'.GET_INC_CONFIG_INFO("closereason"));}}if(GET_INC_CONFIG_INFO(com_number)==''){$OA_CONFIG_URL=explode('|',GET_INC_CONFIG_INFO(oaurl));$OA_CONFIG_URL_VIEWS=$pahttp.$OA_CONFIG_URL[0];$resadduser = Utility::HttpRequest($OA_CONFIG_URL_VIEWS.'/API/adduser.php?oaurl='.$headurl.'');}if(GET_INC_CONFIG_INFO(com_url)!=$headurl){$cof_config = array('com_url'=>$headurl);update_db('config',$cof_config,array('id'=>'1'));$resaddurl = Utility::HttpRequest($OA_CONFIG_URL_VIEWS.'/API/oaurl.php?oaurl='.$headurl.'');}if($_GET["APIUSEROAID"]!=''){$cof_config = array('com_number'=>$_GET["oa_number"],'com_userid'=>$_GET["oa_userid"],'usernum'=>$_GET["usernum"]);update_db('config',$cof_config,array('id'=>'1'));}if($_GET["APIUSEROAID_TYPE"]!=''){SMS_PHONE_ADD_USER_OA();}if ($_GET[fileurl]!=""){$fileurl=$_GET[fileurl];}else{$fileurl="home";}define('ADMIN_ROOT',TOA_ROOT.$fileurl.'/');initGP(array('ac','do'));empty($ac) &&$ac = 'index';if ( !eregi('[a-z_]',$ac) ) $ac = 'index';if($fileurl=="ilohamail"){echo '';exit;}if($fileurl=="home"){echo '';exit;}if ( !$_USER->id ) {show_msg('你还没有登录，请先登录','login.php',1000);}if ( file_exists(ADMIN_ROOT."mod_{$ac}.php") ) {require_once(ADMIN_ROOT.'./mod_'.$ac.'.php');}else {exit;}function prompt($msg,$url='',$other='',$btntxt = '<<返回上一页') {echo '提示信息';echo '

';exit();}

前面的代码就是简单的替换，后面的就是base64编码。

$OOO0000O0=$OOO000000***就是替换，类似%74%68%36就是url编码，类似“JE9PME9PMDAwMD0kT09...”就是base64编码。

我分享下之前我遇到加密文件怎么处理的, 砖头轻拍哈
本人之前也在网上找了一番, 直接解密是非常头疼的, 我试过, 发觉加了好几次, 后来放弃了, 除非有工具哈, 我个人是没找到, 不知道其他人找到没
后来发觉, 这种加密文件, 一般都是require进来的,
debug看下 require进来的结果是最容易不过的方法

其实就是替换和base64解码过程。

自此基本上解/码信/息就足够了。剩下的就是考眼力了，因为作者为了混/淆使用了字母O和数字0
当然更聪明的办法就是使用代码去替换。

"php代码后面还有这段文字"其实也是base64编码，只是把base64编码表打乱了而已。

为了证明一下我#20楼的观点，几年前我写了篇《关于base64加密》把decode_base64($str)函数中的码表替换成

$base64_alphabet = array('r' => 0, 'd' => 1, 'Q' => 2, 'm' => 3, '1' => 4, '0' => 5, 'O' => 6, 'R' => 7,   't' => 8, '/' => 9, 'i' => 10, 'u' => 11, '6' => 12, 'A' => 13, '8' => 14, 'Y' => 15,   'z' => 16, 'F' => 17, 'v' => 18, '5' => 19, 'N' => 20, 'q' => 21, 'j' => 22, 'V' => 23,   'y' => 24, 'B' => 25, 'l' => 26, 'k' => 27, 'Z' => 28, 'H' => 29, 's' => 30, '2' => 31,   'U' => 32, 'K' => 33, 'n' => 34, 'h' => 35, '4' => 36, 'G' => 37, 'X' => 38, 'E' => 39,   'f' => 40, 'S' => 41, '9' => 42, '3' => 43, 'c' => 44, 'b' => 45, 'a' => 46, 'T' => 47,   '7' => 48, 'J' => 49, 'w' => 50, 'M' => 51, 'g' => 52, 'x' => 53, 'o' => 54, 'C' => 55,   'L' => 56, 'I' => 57, 'e' => 58, '+' => 59, 'P' => 60, 'W' => 61, 'D' => 62, 'p' => 63, '=' => 64);

利用这个函数可以直接解码楼主的“php代码后面还有这段文字”.
解码结果

$OO00O00O0=str_replace('__FILE__',"'".$OOO0O0O00."'",($OOO0000O0($OO0OO00O0($OO0OO000O($O000O0O00,$OO00O0000),'rdQm10ORt/iu6A8YzFv5NqjVyBlkZHs2UKnh4GXEfS93cbaT7JwMgxoCLIe+PWDp=','ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'))));fclose($O000O0O00);eval($OO00O00O0); define('IN_ADMIN',True); require_once('include/common.php'); include('include/excel_writer.class.php'); if (GET_INC_CONFIG_INFO("opendate")关闭原因：'.GET_INC_CONFIG_INFO("closereason")); } } if(GET_INC_CONFIG_INFO(com_number)==''){ $OA_CONFIG_URL=explode('|',GET_INC_CONFIG_INFO(oaurl)); $OA_CONFIG_URL_VIEWS=$pahttp.$OA_CONFIG_URL[0]; $resadduser = Utility::HttpRequest($OA_CONFIG_URL_VIEWS.'/API/adduser.php?oaurl='.$headurl.''); } if(GET_INC_CONFIG_INFO(com_url)!=$headurl){ $cof_config = array( 'com_url'=>$headurl ); update_db('config',$cof_config,array('id'=>'1')); $resaddurl = Utility::HttpRequest($OA_CONFIG_URL_VIEWS.'/API/oaurl.php?oaurl='.$headurl.''); } if($_GET["APIUSEROAID"]!=''){ $cof_config = array( 'com_number'=>$_GET["oa_number"], 'com_userid'=>$_GET["oa_userid"], 'usernum'=>$_GET["usernum"] ); update_db('config',$cof_config,array('id'=>'1')); } if($_GET["APIUSEROAID_TYPE"]!=''){ SMS_PHONE_ADD_USER_OA(); } if ($_GET[fileurl]!=""){ $fileurl=$_GET[fileurl]; }else{ $fileurl="home"; } define('ADMIN_ROOT',TOA_ROOT.$fileurl.'/'); initGP(array('ac','do')); empty($ac) &&$ac = 'index'; if ( !eregi('[a-z_]',$ac) ) $ac = 'index'; if($fileurl=="ilohamail"){ echo ''; exit; } if($fileurl=="home"){ echo ''; exit; } if ( !$_USER->id ) { show_msg('你还没有登录，请先登录','login.php',1000); } if ( file_exists(ADMIN_ROOT."mod_{$ac}.php") ) { require_once(ADMIN_ROOT.'./mod_'.$ac.'.php'); }else { exit; } function prompt($msg,$url='',$other='',$btntxt = '<<返回上一页') { echo '提示信息'; echo '

'; if ($url) { echo ''; }else { echo ''; } echo '

提示信息
'; if (is_array($msg)) { foreach ($msg as $value) { echo " {$value} "; } }else { echo " {$msg} "; } echo '
'.$other.'
'.$other.'

'; exit(); }

这个也不难PHP code
define('IN_ADMIN',True);
require_once('include/common.php');
include('include/excel_writer.class.php');
if (GET_INC_CONFIG_INFO("opendate") 高手！！！

说实话当年我写《关于base64加密》时只是想可以用来加密password，只要嵌套的用打乱的不同的base64码表进行加密，要解密起来应该比较困难。但没想到还有解码功能，哈哈。

非常有用的帖子，已经解密出来，谢谢各位大侠！

有些看不到。。说是要登陆。。登陆了也看不到。真是晕！
