Description

Overview

The Avaya Argent Office reboots in response to certain malformed DNS packets, resulting in a denial of service condition.

Description

The Avaya Argent Office reboots when a packet with an empty payload is sent to UDP port 53 (DNS) on its internal interface. By sending repeated packets to this interface, it is possible to cause the device to reboot continuously, resulting in a denial of service condition.


Impact

This vulnerability allows attackers on the same shared network segment to reboot affected devices, thus creating a denial of service condition.


Solution

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