VAR-202103-0433
Vulnerability from variot - Updated: 2023-12-18 13:47Rockwell Automation MicroLogix 1400 Version 21.6 and below may allow a remote unauthenticated attacker to send a specially crafted Modbus packet allowing the attacker to retrieve or modify random values in the register. If successfully exploited, this may lead to a buffer overflow resulting in a denial-of-service condition. The FAULT LED will flash RED and communications may be lost. Recovery from denial-of-service condition requires the fault to be cleared by the user. Rockwell Automation Provided by the company MicroLogix 1400 Received Modbus Buffer overflow vulnerability due to packet processing (CWE-120) Exists. As a result, a buffer overflow occurs, and FAULT LED Flashes red and communication may be lost.Service operation obstruction by a remote third party (DoS) You may be attacked. Micrologix 1400 is a programmable logic controller introduced by Rockwell Automation
