I can concur that today when I did a Nessus scan of my media server, running 9.1 with SP3. It is now vulnerable again to the Backup Exec Server Remote Registry Access Vulnerability.
To prove my Nessus scan, I tried Metasploit against that vulnerability, and it exploited my media server successfully. After running the exploit, beserver.exe begins using 50% of the CPU and remains like that until I restart the machine or the service.
