Description
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. This issue has been fixed in version 2026.4
