Description:
Core Security Technologies has reported a vulnerability in Invensys Wonderware InTouch, which can be exploited by malicious people to cause a DoS (Denial of Service).

This can be exploited to cause the service to crash via a specially crafted Registration packet containing an overly large length field sent to default port 5413/TCP.

The vulnerability is reported in WonderWare InTouch 8.0. Other versions and products with WonderWare SuiteLink versions prior to 2.0 Patch 01 may also be affected.
