CVE-2022-27582Network attack vector

Unauthenticated privilege escalation via password recovery

Published Nov 1, 2022 · Updated May 6, 2025

Missing authentication in SICK SIM4000 password recovery allows remote attackers to gain RecoverableUserLevel access over the network. The recovery method accepts unauthenticated network requests and grants the recoverable user level without checking the required authentication rights. No existing account or user interaction is required; the gained privileges permit actions that affect device data and operation.
