CVE-2025-12031Network attack vector

Cookie disclosure via missing response attributes

Published Oct 21, 2025 · Updated Oct 21, 2025

Sensitive-cookie exposure in Azure Access Technology BLU-IC2 and BLU-IC4 1.19.5 and earlier allows remote authenticated users to read cookies. The controllers' HTTP interface emits sensitive cookies without Secure and HttpOnly attributes, exposing their values to JavaScript in the browser context. The vendor does not identify the affected cookies or disclose how attacker-controlled JavaScript reaches that context, so the demonstrated consequence is limited to cookie disclosure.
