Version: 7.2.2 and earlier
Severity level: High

Nixu Namesurfer implements a unified system for manageming DNS servers via web interface.
The specialists of the Positive Research center have detected a Single Sign-On vulnerability in Nixu Namesurfer.
All services used by the Nixu Namesurfer software (PostgreSQL, Apache) use the same user account to operate. Therefore, a weakness in one of the services will affect all of them. For example, an "Arbitrary file reading" vulnerability in the web server allows an attacker to read the DB file and get records from a DB table as well.
