CVE-2025-12365Network attack vector

Information disclosure via error-filled HTTP headers

Published Oct 27, 2025 · Updated Oct 27, 2025

Information disclosure in Azure Access Technology BLU-IC2 and BLU-IC4 1.19.5 and earlier allows remote attackers to read error data. The controllers' HTTP error handling places error-message content into response headers instead of containing it in an error body. No authentication or user interaction is required; exposure is limited to information included in generated error messages.
