Vulnerability Leaks MicroLogix PLCs to DoS Attacks-01-01

A high-severity vulnerability disturbing the Rockwell Automation’s MicroLogix 1100 programmable logic controllers (PLCs) could be exploited – especially to cause a device to enter an obstinate fault condition.

According to the company advisories in association with US Cybersecurity and Infrastructure Security Agency, any remote, unauthenticated attacker may exploit CVE-2021-33012. This can led to cause a denial of service condition on the targeted controller with the help if specially crafted commands.

Exploitation of this security vulnerability stops the PLC from entering a RUN state. According to Rockwell, “If successfully exploited, this vulnerability will cause the controller to fault when the controller is switched to RUN mode.”
