CVE-2026-22911Network attack vector

Unauthorized access via exposed firmware password hashes

Published Jan 15, 2026 · Updated Jan 15, 2026

Credential exposure in SICK AG TDC-X401GL all versions allows remote attackers to recover system-account passwords from firmware updates. The firmware update files expose password hashes for system accounts, but SICK has not disclosed the responsible file, field, or packaging operation. Obtaining an update file is the required gate; recovered credentials grant unauthorized device access, while no integrity or availability impact is established.
