CVE-2025-49187Network attack vector

Unauthenticated username enumeration via distinct login errors

Published Jun 12, 2025 · Updated Jun 12, 2025

Observable response discrepancy in SICK Field Analytics all versions allows remote attackers to enumerate valid usernames during login. The login handler returns one error for an incorrect password and a different error for a nonexistent username. No authentication or user interaction is required; repeated failed requests reveal which candidate accounts exist but do not expose passwords.
