CVE-2025-31975

Information disclosure via exposed server banners

Published May 6, 2026 · Updated May 6, 2026

Server-banner disclosure in HCL BigFix Service Management 23 allows attackers to read software versions and system details. The service response exposes identifying banner data to requesters instead of suppressing version and system metadata. HCL rates access as adjacent-network, unauthenticated, high-complexity, and user-interaction dependent; the direct impact is reconnaissance data disclosure.
