CVE-2026-22910Network attack vector

Unauthorized access via hidden default credentials

Published Jan 15, 2026 · Updated Jan 15, 2026

Weak credentials in SICK AG TDC-X401GL all versions allow remote attackers to access hidden user levels through default passwords. The authentication configuration for hidden user levels retains weak, publicly known defaults instead of requiring unique credentials. Network access is sufficient for unauthenticated attempts; successful use grants the hidden account's privileges, whose exact scope SICK has not disclosed.
