Vulnerability Note VU#822019

Avaya Argent Office requests 'HoldMusic' file from broadcast address via TFTP

Overview

This vulnerability allows unauthenticated users to upload call holding music to affected devices.

I. Description

The Avaya Argent Office sends broadcast TFTP requests to obtain a file named "HoldMusic" that is used to supply hold music for customers who dial into the device. Therefore, an attacker who can listen to traffic on the same network segment as the device's administrative interface can reply to the TFTP request with an alternate music file.

II. Impact

This vulnerability allows attackers on the same shared network segment to replace the file used for call holding music.

III. Solution

The CERT/CC is currently unaware of a practical solution to this problem.
