#
#Class: Information Disclosure			Severity: Medium
#
#
#Overview:
#---------
#Avaya IP Office Manager TFTP Server Version 8.1 is prone to a Directory
#Traversal vulnerability.
#
#
#Technical Description:
#----------------------
#The vulnerability is caused due to improper validation to Read Request
#Parameter containing '../' sequences, which allows attackers to read
#arbitrary files via directory traversal attacks.
#
#
#Impact:
#--------
#Successful exploitation could allow an attacker to to obtain sensitive
#information, which can lead to launching further attacks.
#
#
#Affected Software:
#------------------
#Avaya IP Office Manager TFTP Server Version 8.1
#
#
#Tested on:
#-----------
#Avaya IP Office Manager TFTP Server Version 8.1 on Windows XP SP3.
