1、ECShop存在一个盲注漏洞,问题存在于/api/client/api.php文件中,提交特制的恶意POST请求可进行SQL注入攻击,可获得敏感信息或操作数据库。
路径:/api/client/includes/lib_api.php
参照以下修改:
推荐(免费):eschop
function API_UserLogin($post) { /* SQL注入过滤 */ if (get_magic_quotes_gpc()) { $post['UserId'] = $post['UserId']; } else { $post['UserId'] = addslashes($post['UserId']); } /* end */ $post['username'] = isset($post['UserId']) ? trim($post['UserId']) : '';
2、ecshop的后台编辑文件/admin/shopinfo.php中,对输入参数id未进行正确类型转义,导致整型注入的发生。
路径: /admin/shopinfo.php
参照以下修改(53-71-105-123行):
源代码: admin_priv('shopinfo_manage'); 改为: admin_priv('shopinfo_manage'); $_REQUEST['id'] = intval($_REQUEST['id']);
3、文件/admin/affiliate_ck.php中,对输入参数auid未进行正确类型转义,导致整型注入的发生。
参照以下修改(31行和51行):
源代码: $logdb = get_affiliate_ck(); 改成: $_GET['auid'] = intval($_GET['auid']); $logdb = get_affiliate_ck();
注:好像按上面改了阿里云还是会提示这个漏洞,然后我在文件顶部处添加以下代码就可以了:
$_GET['auid'] = intval($_GET['auid']);
4、ecshop的/admin/comment_manage.php中,对输入参数sort_by、sort_order未进行严格过滤,导致SQL注入。
参照以下修改:
$filter['sort_by'] = empty($_REQUEST['sort_by']) ? 'add_time' : trim(htmlspecialchars($_REQUEST['sort_by'])); $filter['sort_order'] = empty($_REQUEST['sort_order']) ? 'DESC' : trim(htmlspecialchars($_REQUEST['sort_order']));
5、ecshop没有对会员注册处的username过滤,保存重的用户信息时,可以直接写入shell。
路径:/admin/integrate.php
大概109行,参照以下修改:
$code = empty($_GET['code']) ? '' : trim(addslashes($_GET['code']));
大概601行,参照以下修改:
源代码: @file_put_contents(ROOT_PATH . 'data/repeat_user.php', $json->encode($repeat_user)); 修改成: @file_put_contents(ROOT_PATH.'data/repeat_user.php','<?php die();?>'.$json->encode($repeat_user));
注:好像按上面改了阿里云还是会提示这个漏洞,然后我在文件顶部处添加以下代码就可以了:
$_GET['code'] = empty($_GET['code']) ? '' : trim(addslashes($_GET['code']));
6、ecshop后台模版编译导致黑客可插入任意恶意代码。
路径:/admin/edit_languages.php
大概在第120行
$dst_items[$i] = $_POST['item_id'][$i] .' = '. '"' .$_POST['item_content'][$i]. '";';
修改为
$dst_items[$i] = $_POST['item_id'][$i] .' = '. '\'' .$_POST['item_content'][$i]. '\';';
7、ecshop过滤不严导致SQL注入漏洞。
路径:/category.php 、 /ecsapi/category.php
修改方法:https://www.cnblogs.com/LittleHann/p/4524161.html
8、ecshop的/includes/lib_insert.php文件中,对输入参数未进行正确类型转义,导致整型注入的发生。
有$arr['num'] 、$arr['id']、$arr['type']
这些参数的,在函数开头加上:
大概289行加上: $arr['num'] = intval($arr['num']); $arr['id'] = intval($arr['id']); 大概454行加上: $arr['id'] = intval($arr['id']); $arr['type'] = addslashes($arr['type']); 大概495行加上: $arr['id'] = intval($arr['id']);
9、ECSHOP支付插件存在SQL注入漏洞,此漏洞存在于/includes/modules/payment/alipay.php文件中,该文件是ECshop的支付宝插件。由于ECShop使用了str_replace函数做字符串替换,黑客可绕过单引号限制构造SQL注入语句。只要开启支付宝支付插件就能利用该漏洞获取网站数据,且不需要注册登入。
搜索代码: $order_sn = str_replace($_GET['subject'], '', $_GET['out_trade_no']); 将下面一句改为: $order_sn = trim(addslashes($order_sn));

详情描述参考:https://www.cnblogs.com/LittleHann/p/4272255.html
漏洞文件:/admin/mail_template.php 和 /includes/cls_template.php
/admin/mail_template.php文件添加以下代码(过滤了部分php关键词)
/*------------------------------------------------------ */ //-- 保存模板内容 /*------------------------------------------------------ */ elseif ($_REQUEST['act'] == 'save_template') { if (empty($_POST['subject'])) { sys_msg($_LANG['subject_empty'], 1, array(), false); } else { $subject = trim($_POST['subject']); } if (empty($_POST['content'])) { sys_msg($_LANG['content_empty'], 1, array(), false); } else { $content = trim($_POST['content']); } $type = intval($_POST['is_html']); $tpl_id = intval($_POST['tpl']); /*过滤了部分php关键词*/ $temp_check = preg_replace("/([^a-zA-Z0-9_]{1,1})+(extract|parse_str|str_replace|unserialize|ob_start|require|include|array_map|preg_replace|copy|fputs|fopen|file_put_contents|file_get_contents|fwrite|eval|phpinfo|assert|base64_decode|create_function|call_user_func)+( |\()/is", "", $content); $temp_check = preg_replace("/){0,1}|){0,1}|){0,1}|<script>]+language[^>]*=[^>]*php[^>]*>[^><]*(<\/script\s*>){0,1}/iU", "", $temp_check); $content = $temp_check; /*过滤了部分php关键词*/ $sql = "UPDATE " .$ecs->table('mail_templates'). " SET ". "template_subject = '" .str_replace('\\\'\\\'', '\\\'', $subject). "', ". "template_content = '" .str_replace('\\\'\\\'', '\\\'', $content). "', ". "is_html = '$type', ". "last_modify = '" .gmtime(). "' ". "WHERE template_id='$tpl_id'"; if ($db->query($sql, "SILENT")) { $link[0]=array('href' => 'mail_template.php?act=list', 'text' => $_LANG['update_success']); sys_msg($_LANG['update_success'], 0, $link); } else { sys_msg($_LANG['update_failed'], 1, array(), false); } }</script>
/includes/cls_template.php文件替换函数(fetch_str()):
function fetch_str($source) { if (!defined('ECS_ADMIN')) { $source = $this->smarty_prefilter_preCompile($source); } $source=preg_replace("/([^a-zA-Z0-9_]{1,1})+(copy|fputs|fopen|file_put_contents|fwrite|eval|phpinfo)+( |\()/is", "", $source); $source=preg_replace("/||<script>]+language[^>]*=[^>]*php[^>]*>[^><]*<\/script\s*>/iU", "", $source); return preg_replace("/{([^\}\{\n]*)}/e", "\$this->select('\\1');", $source); //return preg_replace_callback("/{([^\}\{\n]*)}/", function($r) { return $this->select($r[1]); }, $source);//修饰符 /e 在 PHP5.5.x 中已经被弃用了 }</script>
