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 installed 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.
