## Affected

- Asseco Poland S.A. mMedica: fixed in 11.9.5

## Description

An unauthenticated user can connect to a publicly accessible database using arbitrary credentials. The system grants full access to the database by leveraging a previously authenticated connection through a "mmBackup" application. This flaw allows attackers to bypass authentication mechanisms and gain unauthorized access to database with sensitive data. This issue affects Asseco mMedica in versions before 11.9.5.
