I am having the same issue. I am currently doing the Attacking Web Applications with ffuf module in the academy. I got through he subdirectory part without issue, could easily fuzz any of the IPs/Ports, but when i get to the dns section and it steps you through fuzzing the subdomains of https://hackthebox.eu it fails every time I try, am i supposed to be able to do this from within the pwnbox?
Steps i’ve taken:
added ip address for hackthebox.eu to etc hosts
tried to ping hackthebox.eu, google, 8.8.8.8. all fail.
traceroute fails to every site and IP address.
ifconfig/ip a shows tun0 connected to 10.10.14.45
if I go back in the module an load a machine, i can connect to that without issue. If i resolve it in etc hosts to academy.htb that works fine too.
I’m probably just going to do the ffuf fuzz of https://hackthebox.eu in my kali box as that works completely fine.
Not sure whats going on but i hope i find a way to fix it soon cause pwnbox is much more convenient than connecting my kali to vpn.
