Vulnerabilities

Comarch ERP Optima client connects to a database using a high privileged account regardless of an application account to which a user logs in.

Comarch ERP Optima client makes use of a hard-coded password for a database user.

Use of a hard-coded password for a special database account created during Comarch ERP XL installation allows an attacker to retrieve embedded sensitive data stored in the database.

The database access credentials configured during installation are stored in a special table, and are encrypted with a shared key, same among all Comarch ERP XL client installations.

Comarch ERP XL client is vulnerable to MS SQL protocol downgrade request from a server side, what could lead to an unencrypted communication vulnerable to data interception and modification.
