      Then again, I'm putting together a CTF vulnimage and it's definitely going to be systemd-based. Bonus if you pwn it that way!https://twitter.com/marsroverdriver/status/881550176384503808 …

      And people have mocked me for switching to a systemd-free Linux distribution (@DevuanOrg). Yeah, so ... yeah. This is why I did that. https://twitter.com/diodesign/status/881297275070234624 …

      please come up with an attack vector where you're already root and need root. Did you even understand this """vulnerability"""?

      I already have, but I'd be spoiling CTF levels if I went into details ;)

      If it relies on some really dumb setup like generating unit files from unprivileged user input, then there's many ways to abuse that

      There are also many ways to get it right were it not for this systemd stupidity.

      Is it stupid systemd behaviour? Yes, absolutely. Is it a security vulnerability on any real-world system? No.

      There are *tons* of shared-hosting style services that rely on this kind of dynamic user account creation and might be using systemd.
