Introduction:
=============
Das Command Center® ermöglicht die zentrale Verwaltung, Konfiguration und Überwachung von bis zu 500 gateProtect xUTM 
Appliances bzw. Firewall-Systemen. Alle gateProtect Appliances, von der GPO 75 bis zur GPZ 2500, können zentral über das 
Command Center® verwaltet und konfiguriert werden. Dies ist besonders für Unternehmen wichtig, die mehrere Firewall-Systeme 
im Einsatz haben oder größere Rollouts planen.

Status:
========
Published


Affected Products:
==================

Exploitation-Technique:
=======================
Local


Severity:
=========
Medium


Details:
========
The vulnerability is detected in the new user module of the gateprotect software. Local attackers can implement large requests 
to block the configuration load. The bug results in a stable crash & the software needs to be repaired/restored after.

Vulnerable Module(s):
            [+] New User & Firewall Admin Configuration Input Fields
