      Ghidra opens up JDWP in debug mode listening on port 18001, you can use it to execute code remotely 🤦‍♂️.. to fix change line 150 of support/launch.sh from * to 127.0.0.1 https://static.hacker.house/releasez/expl0itz/jdwp-exploit.txt …

      It doesn't seem true here, I think only if you use the support script. I guess it was intended to allow a support engineer to debug problems remotely, it seems to be documented. 🤷‍♂️

          It's only if you use "debug" as a launch mode instead of "fg" or "bg" (default). I wouldn't expect it to open a remotely accessible debug port, I would expect it to have listened on localhost. YMMV but I've exploited it already for RCE.

          Is using an intentional debug interface really an RCE?

          It's not opening the port on my system either.

          So it looks like this only runs when you turn their debugging on. It doesn't seem to be on by default. pic.twitter.com/nFRLzb5Bpr

          I see your documentation, and I raise you a "I didn't read it". Checkmate.
