蚂蚁分类getshell
程序介绍：我们毫无保留的告诉你们这个Mymps蚂蚁分类信息系统5.6S多城市版网站源码+新版手机界面纯安装版，去除域名限制，你可以无限制的安装使用，无功能限制，亲测保证稳定运行。此程序部分核心文件是用zend加密的，但不影响使用。如果你安装不上，原因很简单就是服务器环境问题。
/member/include/inc_shop.php
if($if_corp == 1){ //??????????? if($ac == 'base'){ if(empty($tname)) write_msg('','?m=shop&type=corp&error=39'); if(empty($areaid)) write_msg('','?m=shop&type=corp&error=40'); $db -> query("UPDATE `{$db_mymps}member` SET tname='$tname',catid='$catids',areaid='$areaid',introduce='$introduce',address='$address',busway='$busway',mappoint='$mappoint',msn='$msn',web='$web' $where AND if_corp = '1'"); write_msg('','?m=shop&type=corp&success=13'); } elseif($ac == 'template') { if($_FILES[$name_file]['name']){ require_once MYMPS_INC.'/upfile.fun.php'; $destination = "/banner/".date('Ym')."/"; $mymps_p_w_picpath = start_upload($name_file,$destination,0,'','',$oldbanner,''); |
前面的ac不用管就是if判断然后进入操作而已。我们主要看template这里，获取$name_file的上传内容然后传入start_upload，这里说一下传参中可控的有$oldbanner
看下函数内容
function start_upload( $file_name, $destination_folder, $watermark = 0, $limit_width = "", $limit_height = "", $edit_filename = "", $edit_pre_filename = "" ) { global $mymps_global; global $timestamp; if ( !is_uploaded_file( $_FILES[$file_name]['tmp_name'] ) ) { write_msg( "请重新选择您要上传的图片!" ); } $file = $_FILES[$file_name]; @createdir( MYMPS_UPLOAD.$destination_folder ); $file_name = $file['tmp_name']; $pinfo = pathinfo( $file['name'] ); $ftype = $pinfo['extension']; $fname = $pinfo[basename]; if ( empty( $edit_filename ) && empty( $edit_pre_filename ) ) { $destination_file = $timestamp.random( ).".".$ftype; $destination = MYMPS_UPLOAD.$destination_folder.$destination_file; $small_destination = MYMPS_UPLOAD.$destination_folder."pre_".$destination_file; } else { $destination = MYMPS_ROOT.$edit_filename; $small_destination = MYMPS_ROOT.$edit_pre_filename; $forbidarray = array( MYMPS_ROOT."/p_w_picpaths/logo.gif", MYMPS_ROOT."/p_w_picpaths/nopic.gif", MYMPS_ROOT."/p_w_picpaths/nophoto.jpg", MYMPS_ROOT."/p_w_picpaths/noavatar.gif", MYMPS_ROOT."/p_w_picpaths/noavatar_small.gif" ); if ( !in_array( $destination, $forbidarray ) || $destination != MYMPS_ROOT ) { @unlink( $destination ); } if ( !in_array( $small_destination, $forbidarray ) || $destination != MYMPS_ROOT ) { @unlink( $small_destination ); } unset( $forbidarray ); } if ( file_exists( $destination ) ) { write_msg( "同名图片已存在，请重新选择您要上传的图片！" ); } if ( !move_uploaded_file( $file_name, $destination ) ) { write_msg( "图片上传失败，请重新选择您要上传的图片！" ); } |
看这里
$file = $_FILES[$file_name]; @createdir( MYMPS_UPLOAD.$destination_folder ); $file_name = $file['tmp_name']; $pinfo = pathinfo( $file['name'] ); $ftype = $pinfo['extension']; $fname = $pinfo[basename]; |
先是获取了文件内容然后获取了文件后缀以及文件名这些
{ $destination = MYMPS_ROOT.$edit_filename; $small_destination = MYMPS_ROOT.$edit_pre_filename; $forbidarray = array( MYMPS_ROOT."/p_w_picpaths/logo.gif", MYMPS_ROOT."/p_w_picpaths/nopic.gif", MYMPS_ROOT."/p_w_picpaths/nophoto.jpg", MYMPS_ROOT."/p_w_picpaths/noavatar.gif", MYMPS_ROOT."/p_w_picpaths/noavatar_small.gif" ); |
这里的edit与edit_pre讲道理的是非空所以进入了该if进行后缀以及路径拼接(期间并无任何效验)
if ( file_exists( $destination ) ) { write_msg( "同名图片已存在，请重新选择您要上传的图片！" ); } if ( !move_uploaded_file( $file_name, $destination ) ) { write_msg( "图片上传失败，请重新选择您要上传的图片！" ); } |
下面接着判断了是否存在相同名如果不存在同名则直接上传。
本地复现:
Old我们指定的文件名
不过印象中我并不记得蚂蚁分类会存在这个漏洞啊！！抱着各种心情多看一下.随便看一个
发现除了我们那个每个上面都会有一个check_upp_w_picpath的调用 看看怎么回事
