Description

CERT Polska has received a report about vulnerabilities in Comarch ERP Optima software and participated in coordination of their disclosure.

The vulnerability CVE-2025-68420: Comarch ERP Optima client connects to a database using a high privileged account regardless of an application account to which a user logs in. It is possible for a local attacker who controls the client process to dump it's memory, extract credentials and use them to gain a privileged access to the database. In order to exploit this vulnerability, the client application has to be already configured, but a user does not have to be logged in.

The vulnerability CVE-2025-68421: Comarch ERP Optima client makes use of a hard-coded password for a database user. These credentials cannot be changed. It is possible for a remote attacker to gain an access to the database with elevated privileges including executing system commands on a server.

Both issues have been fixed in version 2026.4.
