CVE-2025-12364Network attack vector

Account compromise via insufficient password strength enforcement

Published Oct 27, 2025 · Updated Oct 27, 2025

Weak password requirements in Azure Access Technology BLU-IC2 and BLU-IC4 through 1.19.5 allow remote attackers to compromise accounts. The firmware authentication policy accepts passwords that do not meet adequate strength requirements, reducing the search space for guessing. Network access to a controller login and a known username are required; the vendor has not published the exact missing rules or affected account classes.
