CVE-2025-1688Network attack vector

Protection bypass via upgrade-induced password reset

Published Apr 15, 2025 · Updated Sep 9, 2025

Default-key use in Milestone Systems XProtect VMS 24.1 through 24.2 allows remote authenticated users to reset its configuration password. The 2024 R1 and 2024 R2 upgrade installers replace the Management Server's optional system configuration password when upgrading an older deployment. Exploitation requires high privileges and the affected upgrade path; the reset leaves the system configuration without its intended encryption protection.
