Introduction:
=============
ServersCheck is a Belgian based and privately owned technology company founded in 2003.
It is most known in the Network Administrator community for its software program monitoring the availability and performance of 
servers and other networked devices. Next to this it also offers environmental sensors; providing monitoring from both the inside 
and the outside.

ServersCheck Monitoring ist, ein Werkzeug zum Überwachen, Melden und Warnen der Netzwerk- und Systemverfügbarkeit, 
das auf Windowsrechnern läuft. Zusätzlich zur Überwachung von normalen Netzwerkgeräten kann dieses Programm auch die 
Umgebung der Geräte auf Temperatur, Luftfeuchtigkeit, Überschwemmung, überwachen. ServersCheck Software läuft als 
lokaler Dienst und wird über ein Browserbasierendes Interface administriert. Zusätzliche Funktionen enthalten Warnmeldungen 
und stellen Statistiken von langlaufenden Aufzeichnungen grafisch dar.

Appliance:
Die ServersCheck Monitoring Appliance ist eine komplette Browser und SMS basierte Lösung um Serverräume zu überwachen. 
Dieses kleine, leistungsfähige, kostengünstige Gerät kann bis zu 250 Einheiten beaufsichtigen.
Es ist klein: Es paßt auf Ihre Handfläche.

Abstract:
=========
Vulnerability-Lab Team discovered multiple Vulnerabilities on ServersCheck Monitoring Software v8.8.10 & v8.8.6.


Report-Timeline:
================
2011-09-27:	Public or Non-Public Disclosure


Status:
========
Published


Affected Products:
==================
ServersCheck Monitoring Software v8.8.10 & v8.8.6


Exploitation-Technique:
=======================
Remote


Severity:
=========
Medium(+)


Details:
========
1.1
Multiple persistent input validation vulnerabilities are detected on application-side of Serverscheck.
The remote vulnerability allows local low privileged user accounts or remote attackers to manipulate specific sections, areas or 
content requests via Java or HTML script code injection.

Vulnerable Module(s):  (Persistent)
					[*] New Team / Team List
					[*] New User / User List
					[*] Windows Account Edits / Windowsbenutzer Berechtigungsnachweis 
					[*] Rules Size Add
					[*] MSN Accounts Rules & copied Functions
					[*] ServersCheck Protokolldateibetrachter: scan.txt 
					[*] SNMP Trapkonfiguration
					[*] Axis Camera - Add & Configuration
					[*] Neue Überwachungsregel / Observation Rules
					[*] User Diagram / Add
					[*] ODBC Protocol
					[*] SMS TEST SCRIPT

Picture(s):
					../2.png
					../3.png


1.2
Multiple non-persistent input validation vulnerabilities are detected on application-side of Serverscheck.
The vulnerability allows an attacker to hijack customer/admin sessions.
Successful exploitation requires high user inter action.

Vulnerable Module(s): 
					[*] Downtime
					[*] Linenumber
					[*] ID
					[*] Checks2def (Footer/Header)
					[*] Timeline
					[*] Definere Einstellungen zur Dienstanmeldung
					[*] Device Graphs
					[*] View Graphs
					[*] Rules History

Picture(s):
			../1.png


1.3
A cross site request forgery vulnerability is detected on the Dienstanmeldung formular. 
Attackers can force a logon via cross site request forgery attack.

Vulnerable Module(s): 
					[*] Einstellungen zur Dienstanmeldung

1.4
Attackers can create own masks to send mass notifcations on a vendor phone number without any restrictions by the application itself.

Vulnerable Module(s): 
					[*] SMS- & Pager (http://localhost:1272/smstest.html?  &2 :)


Proof of Concept:
=================
The different vulnerabilities can be exploited by local low privileged user accounts, software users or remote attackers. 
For demonstration or reproduce ...

Risk:
=====
1.1 - The security risk of  the persistent vulnerabilities are estimated as medium(+).
1.2 - The security risk of the non-persistent vulnerabilities are estimated as low(+).
1.3 - The security risk of the cross site request forgery attack is estimated as low(+).
1.4 - The security risk of the sms misconfiguration/bug is estimated as low(+).
