New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3.6


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


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.


Upgrade 3S CODESYS Runtime Toolkit to version or higher.
