Severity level

Severity level: High
Impact: Unauthorized Access

CVSS v2:
Base Score: 9.0
Vector: (AV:N/AC:L/Au:S/C:C/I:C/A:C)

CVE: not assigned

Software description

Nixu Namesurfer implements a unified system for manageming DNS servers via web interface.

Vulnerability description

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.

How to fix

Update your sofware up to the latest version
