Description

  • Your Windows build number:
    C:\Users\XXXX>ver
    Microsoft Windows [版本 10.0.18922.1000]

  • What you're doing and what's happening:
    [XXX@XXX ~]$ netstat
    Active Internet connections (w/o servers)
    Proto Recv-Q Send-Q Local Address Foreign Address State
    tcp 0 0 localhost:52742 localhost:x11 ESTABLISHED
    tcp 0 0 localhost:52702 localhost:x11 ESTABLISHED
    tcp 0 0 localhost:52784 localhost:x11 ESTABLISHED
    tcp 0 0 localhost:52700 localhost:x11 ESTABLISHED
    tcp 0 0 localhost:52780 localhost:x11 ESTABLISHED

[ed, KC... some snips]

  • What's wrong / what should be happening instead:
    Host don't share loopback with WSL guest (At least now). Reserve DNS takes host's ip as localhost may be confusing

172.17.58.195 is the ip address of the guest. 172.17.58.193 is the ip address of the host.
The problem occurs on every program using reserve dns.

Research direction

The payload names no files, tests, or entry points. Start by reproducing the WSL2 networking behavior with netstat and comparing localhost resolution and loopback access between the Windows host and WSL guest. Done means the intended localhost sharing behavior is implemented and verified across programs using reserved DNS.
