3S CODESYS Runtime Toolkit < 2.4.7.48 PLCWinNT DoS

medium Nessus Plugin ID 86573

Synopsis

A programmable logic controller (PLC) runtime on the remote host is affected by a denial of service vulnerability.

Description

The 3S CODESYS Runtime Toolkit running on the remote Windows host is affected by a denial of service vulnerability in the PLCWinNT Runtime service (TCP port 1200) due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this to crash the service, via a crafted request that triggers a NULL pointer deference.

Solution

Upgrade 3S CODESYS Runtime Toolkit to version 2.4.7.48 or higher.
