AI-suggested
Until a fix is released, organizations should consider network-level protections such as restricting network access to the PLC, monitoring for brute force attempts, and enforcing strong password policies where possible.
Description
An attacker with network access to the PLC is able to brute force discover passwords to gain unauthorized access to systems and services. The limited password complexity and no password input limiters makes brute force password enumeration possible.
