CVE-2020-3936Network attack vector

Unauthenticated SQL execution via unfiltered interface parameters

Published Mar 27, 2020 · Updated Sep 16, 2024

SQL injection in Unisoon UltraLog Express 1.4.0 allows remote attackers to execute arbitrary SQL through its device-management interface. Specific interface parameters pass user-supplied strings to database queries without filtering, allowing attacker-chosen commands. The network-reachable interface requires no authentication or user interaction, exposing stored data and database integrity to those commands.
