What is CVE-2025-59093?

The Exos 9300 instances employed by Dormakaba utilize a database password derived from predictable static values combined with the hostname and a publicly accessible random string. This design flaw permits an attacker to easily uncover the database password, leading to unauthorized access to the central Exos 9300 database. The compromised user, Exos9300Common, possesses roles that allow reading, updating, and inserting into various tables, thereby potentially exposing sensitive data and functionality to malicious actors.
