I am using Kali linux 2018.2 as a VM in VirtualBox to scan a Metasploitable-VM for vulnerabilities.
My scans are running super slow. I used to scan only one IP (Metasploitable-VM) with the default “full and fast” definitions and it would take about 1-3 hours. (Task Wizard - Quick Scan)
With the newest version of OpenVas with all the updates:
When the Scan starts, I can retrace the comunication with wireshark. After 9072 pakets the scan stocks. The progress shows 1% and the CPU goes to nearly 100%.
My Kali-VM has 12GB Ram and 8 CPUs. So I don’t think that this is a problem of too few RAM. The CPU is a Core i7 4,2GHz. The free command shows 9.8GB of available RAM.
After a long time the scan continues und the CPU relaxes again…
I tried to scan a physical Cisco Router and I have the same trouble.
Anyone run into this before? Have any suggestions?
