Introduction:
=============
Einfach, schnell und zukunftssicher! Die ideale Lösung, um Ihre Filialen und industriellen Zweigstellen rund um den Globus zu schützen.
Endian 4i ist die ideale Lösung für Büroaußenstellen oder Industrieinstallationen. Die Firewall ist in den zwei Varianten „Office“ und
„Industrial“ erhältlich. Die Office-Version bietet alle Funktionen, um Netzwerke in der Firma und in Verbindung mit Außenstellen einfach
und sicher zu verlinken. Derselbe Funktionsumfang ist bei der Industrial-Version vorhanden, die sich speziell an den Industriebereich
richtet und 24V Support bietet sowie auf der Hutschiene installiert werden kann. Remote-Supporting, Remote-Konfiguration, Systemüberwachung
bis hin zur einfachen, sicheren Vernetzung von Außenstellen – die Kostenvorteile dabei liegen auf der Hand. Sichern auch Sie sich die
Konnektivität Ihres Unternehmens ab, und behalten Sie mit der Endian 4i stets die Nase vorn.

Severity:
=========
High
Details:
========
1.1
Multiple persistent input validation vulnerabilities are detected on Endians WAF UTM appliance application.
The vulnerability allows an attacker to manipulate specific application requests via persistent included script codes.
Vulnerable: Input Validation Vulnerabilities (Server-Side|Persistent)
Vulnerable Module(s):
[+] Proxy - HTTP Configuration Masks
[+] Service - Intrusion Prevention
[+] Netzwerk - Host Configuration
[+] DHCP

1.2
Multiple cross site request forgery vulnerabilities are detected on client-side of the edian waf appliance.
The vulnerability allows an attacker to force client-side module requests of application functions.
Vulnerable: Cross Site Request Forgery Vulnerabilities (Client-Side|Non Persistent)
Vulnerable Module(s):
[+] HotSpot - Add Password
[+] System - Passwords
Picture(s):
../csrf1.png
Proof of Concept:
=================
The vulnerabilities can be exploited by remote attackers with high required user inter action or local low privileged user accounts.

Solution:
=========
1.1
Restrict & parse the vulnerable input & output sections to fix the persistent injects.
1.2
Use a csrf tokens & a checkbox to verify a request.
Risk:
=====
The security risk of the persistent vulnerabilities are estimated as high(-).
The security risk of the non-persistent vulnerabilities are estimated as low(+).
