VAR-201912-0997

Vulnerability from variot - Updated: 2023-12-18 10:57

In Omron PLC CS series, all versions, Omron PLC CJ series, all versions, and Omron PLC NJ series, all versions, the software does not implement sufficient measures to prevent multiple failed authentication attempts within in a short time frame, making it more susceptible to brute force attacks. Omron PLC CJ series, etc. are all products of Japan's Omron (Omron) company. Omron PLC CJ series is a CJ series programmable logic controller (PLC). Omron PLC CS series is a CS series programmable logic controller (PLC). Omron PLC NJ series is an NJ series programmable logic controller. Attackers can exploit this vulnerability to implement brute force attacks
