سپس از قسمت Search System در قسمت پیکربندی حالت جستجو را از Standard به Full Text تغییر دهید .

برای پنتست این آسیب پذیری میتونید اکسپلویت رو به صورت HTML ذخیره کنید در قسمت action="http://yourmybb.com/search.php" به جای Yourmybb آدرس سایت خود را قرار دهید .










یکی از تیم های امنیتی راه مقابله با Hک سایت ها 4 1 که البته اسمشم نمیگم اومد این پچ رو خراب کنه ما هم یه عکس قرار میدیم خاطراتی براش زنده بشه . مجدد متذکر میشم اگر مراحل بصورت کامل انجام شود آسیب پذیری رفع میشود .

آسیب پذیری XSS از نوع High از پلاگین Extended Useradmininfo انجمن ساز مای بی بی
















کد:


کد:
# Exploit Title: Extended Useradmininfo MyBB Plugin 1.2.1 - Cross Site
Scripting
# Google Dork: N/A
# Date: 09.02.2014
# Exploit Author: Fikri Fadzil - fikri.fadzil@impact-alliance.org
# Vendor Homepage: http://forum.mybboard.de/user-9022.html
# Software Link: http://mods.mybb.com/view/extended-useradmininfo
# Version: 1.2.1
# Tested on: PHP

Description:
This plugin shows advanced Informations about a user, such as last IP, User
Agent, Browser and Operating System. The information will be shown in a
user profile and visible only  for people who are able to see the
adminoptions on user profiles.

Proof of Concept
1. Create a user account.
2. Change your user-agent to "Mozilla<script>alert(1)</script>".
3. Login and then... logout.

* The script will be executed whenever the administrator view your profile.

قابل توجه دوستان عده ای افراد غیر فنی شایعاتی در مورد آسیب پذیر بودن پچ پخش کرده اند . که البته مدتی قبل توسط همین آسیب پذیری کوکی کاربرانشان سرقت و در نهایت Hک شدند .

بنده خاطر نشان میکنم که پچ مورد نظر بدون مشکل میباشد و توسط بخش فنی MYBB مورد تایید قرار گرفته است .

عزیزانی که آسیب پذیری XSS در search.php آنها شناسایی شده است میتوانند این آسیب پذیری را با جایگزین کردن کد بالا پچ نمایند .
