## Technical details

The vulnerability is a time-based blind SQL injection in the CheckConflictOfDates endpoint (index.php?module=Appointments&action=CheckConflictOfDates&ajaxSkipHeader=true). The userId parameter is not properly sanitized before being included in a SQL query, allowing an attacker to inject arbitrary SQL code. The attack requires authentication (login to the application) and network access to the CRM+ instance. An attacker can use time-based techniques or automated tools like SQLMap to extract data from the underlying MySQL database. Versions 2025.6 and earlier are affected; patch availability from Brainformatik has not been confirmed in the advisory.
