Hirschmann HiOS Switches Race Condition (CVE-2019-12263)

high Tenable OT Security Plugin ID 502272

Synopsis

The remote OT asset is affected by a vulnerability.

Description

This vulnerability relies on a race-condition between the network task (tNet0) and the receiving application. It is very difficult to trigger the race on a system with a single CPU-thread enabled, and there is no way to reliably trigger a race on SMP targets.

This plugin only works with Tenable.ot.
