---------------------------------
Empire CMS is a widely used CMS in china. Official website is www.phome.net.
I have found a remote PHP code-execution vulnerability in EmpireCMS 6.6 (the lastest version).
This issue occurs in the application's template parser.
An
attacker can exploit this issue by enticing an unsuspecting victim to
install a malicious template,can inject and execute arbitrary malicious
PHP code in the context of the webserver process.
This may facilitate a compromise of the application and the underlying system; other attacks are also possible.
[-] details :
Here is a function for template parser in /e/class/connect.php
---------------------------------
function ReplaceListVars($no,$listtemp,$subnews,$subtitle,$formatdate,$url,$haveclass=0,$r,$field,$docode=0){
global $empire,$public_r,$class_r,$class_zr,$fun_r,$dbtbpre,$emod_r,$class_tr,$level_r,$navclassid,$etable_r;
if($haveclass)
{
$add=sys_ReturnBqClassname($r,$haveclass);
}
if(empty($r[oldtitle]))
{
$r[oldtitle]=$r[title];
}
if($docode==1)
{
//here is the vul code
//$listtemp is passed to function eval and not checked.
$listtemp=stripSlashes($listtemp);
eval($listtemp);
}
......
}
---------------------------------
Many other files used this function,here is one place:
---------------------------------
// /e/action/ListInfo/index.php line 120
//get template from datebase which may contain PHP code we have injected into database.
$tempr=$empire->fetch1("select
tempid,temptext,subnews,listvar,rownum,showdate,modid,subtitle,docode
from ".GetTemptb("enewslisttemp")." where tempid='$tempid'");
......
$listtemp=$tempr[temptext];
$rownum=$tempr[rownum];
if(empty($rownum))
{$rownum=1;}
$formatdate=$tempr[showdate];
$subnews=$tempr[subnews];
$subtitle=$tempr[subtitle];
$docode=$tempr[docode];
$modid=$tempr[modid];
$listvar=str_replace('[!--news.url--]',$public_r[newsurl],$tempr[listvar]);
// $listvar contain PHP code we have injected
......
while($r=$empire->fetch($sql))
{
$repvar=ReplaceListVars($no,$listvar,$subnews,$subtitle,$formatdate,$url,$have_class,$r,$ret_r,$docode);
//here lead to execute php code
