CVE-2023-5570Network attack vector

Unauthenticated account enumeration via distinguishable responses

Published Oct 27, 2023 · Updated May 21, 2026

Account-footprinting in inohom Home Manager Gateway before 1.27.12 allows remote attackers to enumerate user accounts. The CNA identifies improperly protected outbound error messages or alerts but does not disclose the request, response field, or comparison that distinguishes valid accounts. No authentication or user interaction is required, and the documented consequence is limited to disclosure of account existence.
