Published


Affected Product(s):
====================
Barracuda Networks
Product: CudaTel - Communication Server 2.0.029.1


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


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


Technical Details & Description:
================================
Multiple persistent Input Validation vulnerabilities are detected on Barracudas CudaTel Phone Application v3.0.028.001. 
Local low privileged user accounts can implement/inject malicious script code to manipulate modules via persistent context 
requests. 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.

Proof of Concept (PoC):
=======================
The vulnerabilities can be exploited by local privileged user accounts with low user inter action or remote via manipulated 
http request & high required user inter action. For demonstration or reproduce ...
