### DISCLAIMER
# Script provided 'as is', without any warranty.
# For educational purposes only.

### Software Description
# The Centreon Software Suite is a set of modular software programs designed for managing
# and controlling your information systems. It lets you supervise and measure performance and
# quality of service so that you can optimise the use of your resources.

### Vulnerability Details
# Vulnerability found in menuXML.php inside the 'menu' parameter. By injecting payload after the
# menu parameter, e.g: ' AND SLEEP(5) AND 'meHL'='meHL, the web application hung for 5 seconds,
# which gives us a conclusion that the web application is vulnerable to time-based sql injection.

## Further notes:

# The script below is for PoC of the vulnerability only.
