Subject: Running adilsoybali log4j tester resets virtual network adapter in Ubuntu 21.10 Linux virtual machine
Subject: Running adilsoybali log4j tester resets virtual network adapter in Ubuntu 21.10 Linux virtual machine
Good day from Singapore,
I have an Ubuntu 21.10 Linux virtual machine running under Oracle VM VirtualBox 6.1. Host operating system is Windows 10 Pro. The virtual network card is operating in NAT mode.
Recently I have installed Log4j/Log4shell remote command execution security scanner developed by Adil Soybali. His github link is https://github.com/adilsoybali/Log4j-RCE-Scanner/
When I run adilsoybali log4j tester, it keeps resetting the virtual network adapter. The internet connection inside the Ubuntu 21.10 Linux virtual machine keeps going down from time to time. I can't ping machines on the internet from time to time. Ping tests show Destination Host Unreachable. The host operating system which is Windows 10 Pro never loses network connection. Only the virtual machine loses network connection.
The dmesg output is as follows:
