    this is... a very, very old and basic oversight that has been done (and will be done) by many plugin developers that want to use chest GUIs until bukkit/paper/whatever implement a standardised solution.

    I would like to provide some insight into this as I am an amateur server dev, and this exploit came from a very large oversight.
    So server chest guis work by having inventories and using the event to detect when someone clicks an item (as you described)
    What likely happened here was that the developers of vulcan forgot to add proper item checks to what they were clicking, so the server just assumed that they had permissions. Yes, there should be permission checks there. However, it is (from what I've seen) standard practice to add checks to the item clicked such as it having lore (meaning the player couldn't have modified it to have that lore), so that you don't ever accidentally detect them clicking an item in their inventory.
    The oversight of not adding permission checks isn't as egregious as not having the proper item checks for the gui, as its the very first thing you HAVE to get right.

    • @roughlyunderscore
      @roughlyunderscore 3 місяці тому +24

      You're on the right track, I'd also like to provide some insight as an experienced dev.
      A lot of (especially beginner) developers compare their inventories by title - this means that to check if a GUI opened by a player is the GUI that the plugin wants, it compares the title of the GUI. This is wrong on multiple levels - the video shows exactly why.
      You were correct about the lore-for-the-item thing, but also not 100%. From my experience, it's standard to use NBT data for an item (add a tag that identifies this item) - this way it's completely fool proof. On versions of 1.14.4 and above it's especially easy to implement with the PersistentDataContainer API.

    One thing I would like to add is that there is a way to access the main GUI without knowing its name. In my case I used a feather and the chest title "Check Types" which allowed me to access GUIs without knowing the name of the main GUI.

      It is quite a mistake not to check for permissions on the GUIs, which should NEVER happen, but to be fair, frep handled it very well by releasing a free patch for everyone. But I think there will be a lot of servers vulnerable to this exploit for a long time to come.
      Also the video was unlisted, since I released another one right afterwards which included the aspect of Force-OP. :)

    as someone whos been making inventory guis and other various minecraft stuff, i can say that the statement at 18:20 is incorrect, it is *VERY EASY* to check if the inventory instance is correct, and check permissions accordingly. But even if it wasn't, if you're doing scripted events when clicking a gui button, that should 100% BE BEING CHECKED!

    As a developer that has worked on dozens of plugins involving hundreds of inventory GUIs, I take issue with the statement that it's difficult to check. One of my main go to methods of implementing chest UIs was to create a custom inventory container class similar to how all standard inventory types have their own class in the code. Internally in logic it would be identical to a chest UI, but I could then test the player's currently opened ui's class against my custom one. Opening a normal chest or player inventory would result in the currently opened inventory's class being PlayerInventory or DoubleChestInventory (or equivalent as the names have changed at various points in times) but they would not be the custom class.
    On top of that considering the UI is accessed via command and Spigot servers have events for opening and closing inventories in addition to just clicking in the inventories, it's not difficult to keep track of the current inventory of the player.
    All of that is then on top of basic permission checks, it's odd. And it's even stranger that the developer removed the UI entirely instead of just adding the checks to the code. The developer obviously knows what they're doing as making an Anti Cheat is not something someone does on a whim, especially one so well received, so it's baffling this got through.

    There is a force op in 1.2.5 and below that you didn't mention. Back then the Minecraft protocol wasn't encrypted. What this meant is that the connection between clients and servers were not secure and could be tampered by anyone in a MitM attack. The force op worked by getting an admin of the target server join an attacker controlled server. When joining the malicous server, the malicous server would then try and login to the target server and forward the handshake packet back to the admin's client allowing the malicous server to successfully login to the target server as that admin. The malicous server while logged in with the admin account could execute any command including op. The malicous server doesn't have to forward any other packets back to the admin so it can just kick the admin with an error message or have them join a fake server so it isn't suspicious.

    As a skript developer myself I can confirm it is a major pain to do this, but it can be prevented by placing buffer characters like colored spaces after the text is finished like "GUI&a &r" this fixes all your problems and makes it virtually impossible for players to open this gui. I can confirm that like every skript I have seen doesn't check perms, but the all use colored text and that makes it impossible for players to get UI named this way. Third mistake most people missed is that Vulcan checks it based on the item clicked as opposed to a slot, which is kinda of a bummer

I personally prefer going with the built-in NBT tags system. It works well along with the OOP concepts and cannot be easily tampered by players. Though in Vulcan's case they should've used controlled commands like what old-school NCP does in the first place.
