Vulnerable Systems:
* ServersCheck Monitoring Software version 8.8.6 and prior

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 berwachungsregel / 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
A not restricted insert mas?file= parameter request allows an attacker to include local files without right permissions. A successful exploitation process can result in a path traversal.

Vulnerable Module(s):
[*] Logging, Viewalert & Logview (?file=)

1.5
Attackers can create a own mask 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 ...
