#api #params > Ничего не могу найти на сайте, может ещё что-то посмотреть? Иногда встречается сайт, на котором всего лишь несколько конечных точек. Казалось, все параметры были проверены на уязвимости, а в чек-листе отмечены любые возможные проверки на инъекции и логику. Однако, бывают уязвимости, которые не видны с первого взгляда. Например (CAPEC-460) HTTP Parameter Pollution или (CWE-472) External Control of Assumed-Immutable Web Parameter. Данные ошибки возникают из-за неожиданного поведения в функциях обработки параметров. Давайте рассмотрим первую атаку HTTP Parameter Pollution, она состоит из возможности добавления повторяющихся параметров с помощью специальных разделителей запроса. Например, у нас открыт сайт по продаже арбузов в браузере 🌐 example.com/profile.jsp?client_id=1 Для кнопки "Открыть профиль" устанавливается динамически в ответе от сервера html: <a href="profile.jsp?client_id=1&action=view А теперь изменим запрос добавив в него параметр и закодировав разделитель & как %26: 🌐 example.com/profile.jsp?client_id=1%26action%3Ddelete В результате для кнопки "Открыть профиль" задаётся html: <a href="profile.jsp?client_id=1&action=delete&action=view При нажатии на кнопку — профиль пользователя будет удалён. Для того чтобы заставить жертву удалить свой аккаунт, нам нужно отправить ей ссылку и подождать. Это происходит, потому что Apache Tomcat 🐈 при анализе двух одинаковых параметров (action) берёт значение первого: &action=delete&action=view Вот так выглядит код на стороне сервера:
String client_id = request.getParameter("client_id");
GetMethod get = new GetMethod("https://example.com/profile");
get.setQueryString("client_id=" + client_id + "&action=" + action);
href_link=get.URL; Разработчик должен был учесть такое поведение и проверить возможность внедрения параметра action в client_id Вообще, приоритет и процесс обработки параметров можно взять из этой таблицы ниже:
Technology/HTTP backend        | Parsing Result    | Example         |
---------------------------------------------------------------------
ASP.NET/IIS                    | All occurrences   | par1=val1,val2  |
ASP/IIS                        | All occurrences   | par1=val1,val2  |
PHP/Apache                     | Last occurrence   | par1=val2       |
JSP Servlet/Apache Tomcat      | First occurrence  | par1=val1       |
JSP Servlet/Oracle Application | First occurrence  | par1=val1       |
IBM HTTP Server                | First occurrence  | par1=val1       |

Так, для Server: Apache Tomcat будет взято значение из первого совпадения action=delete А для Server: Apache значение уже будет action=view — последний параметр Но не все сервера используют приоритет порядка, так, например, ASP.NET/IIS конкатенирует значения. Поэтому в случаях, когда выполнению XSS мешает санитизация или WAF, можно составить следующий payload: example.com/search?param=<audio/n="&param="src/onerror=alert()> В результате на странице html будет <audio n="," src/onerror=alert()> и XSS успешно сработает 💣 Помимо приоритетов, нужно также вспомнить о разделителях для параметров. Существует не только привычный & (амперсанд) и , (запятая) но и ряд других символов, тут нужно обратиться к стандартам и поискать реализации. Если открыть (rfc6570) URI Template можно найти Path-Style Parameter Обычный URL будет следующим: example.com/users?role=admin&firstName=N А теперь преобразуем его в вид Path-Style: example.com/users;role=admin;firstName=N Использование в качестве разделителя ; (точки с запятой) не повсеместно. Это приводит к различиям обработки во фреймворках и как следствие к уязвимостям, в частности, на микросервисных архитектурах: • CVE-2021-23336 — Python библиотека urllib.parse.parse_qsl не игнорирует точку с запятой. • ParseThru — Go библиотека net/url не игнорирует точку с запятой и выводит предупреждение http: URL query contains semicolon... Следует помнить, что уязвимость HTTP Parameter Pollution может возникать не только в URL, но и в любой части POST/GET запроса, а также в теле JSON. {"client_id":4, "client_id":17, "action":"delete"}
