What is CVE-2026-22920?

SICK devices exhibit a significant vulnerability due to the inadequate salting of stored passwords, which exposes them to potential password extraction attacks. Without proper salting, attackers can utilize pre-computed hash databases to quickly crack passwords, compromising the integrity and security of affected systems. Organizations using SICK devices should implement stronger password management practices and consider updating their systems to mitigate this risk.
