Vulnerability 1: Local Privilege Escalation through Unsecured Database Server
===============================================================================
Acunetix WVS uses a PostgreSQL database in the backend to store all its data. However, because of the disabled authentication for local connections and cleartext credentials within a user readable configuration file, it was possible to gain full control over this database. As the database's Windows service was also configured to run as LOCAL SYSTEM, this could be abused to drop arbitrary file. As documented in the full report, this could further be exploited (using sqlmap) to gain full control over the affected target system.

Vulnerability 2: Local Privilege Escalation through DLL Sideloading 
===============================================================================
Additionally a DLL sideloading vulnerability was discovered in the Acunetix Windows service. As this service was also configured to run as LOCAL SYSTEM, it could also be abused to gain full control over the target.
