KEPServerEX < 6.16.217.0 Denial of Service

medium Nessus Plugin ID 206171

Synopsis

The remote host has software that is affected by a denial of service vulnerability.

Description

The remote host has a version of KEPServerEX installed that is affected by a denial of service vulnerability. When performing an online tag generation to devices which communicate using the ControlLogix protocol, a machine-in-the-middle, or a device that is not configured correctly, could deliver a response leading to unrestricted or unregulated resource allocation. This could cause a denial-of-service condition and crash the Kepware application. By default, these functions are turned off, yet they remain accessible for users who recognize and require their advantages.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade KEPServerEX to version 6.16.217.0 or higher.
