#NODUS TECHNIC LAUNCHER PATCH#

I apologize for spreading information before I knew more.Īs far as I am aware, if you are playing minecraft 1.17+, there is a patch available to the fabric modloader that fixes this exploit. THE JAVA VERSION YOU USE DOES NOT MATTER!!! I’VE CROSSED OUT THE INFORMATION IN THE INITIAL POST THAT IS NOW KNOWN TO BE INCORRECT. For the time being, just avoid playing minecraft multiplayer entirely, unless you are certain that both the client you are using and server you are playing on has patched this issue. I don’t want to give the impression that you could be safe when I’m not sure, so for now don’t even try to play on any server below Minecraft 1.17 at all (or connect to any server using a minecraft client below version 1.17).ĮDIT 2 (7:00 pm): I am seeing a lot of people saying that the JVM flag workaround doesn’t help at all, or that it only helps for minecraft versions 1.17+. It is possible that some misinformation is being spread on this, perhaps to curb the amount of people using this exploit via obfuscation. This contradicts things I’ve seen reading the papermc discord server, but it comes from a reliable source (the fabric modloader developers). Stay safe, everyone.ĮDIT 1 (6:26 pm): The jvm flag workaround only applies to Minecraft 1.17 and later.

I will update this post as more information becomes available. Ī band-aid fix you can apply is to add the following startup flags to Minecraft when launching the game:īut I wouldn’t recommend relying on this, as the server you connect to could still be vulnerable itself.Īgain, I recommend not playing multiplayer at all until mojang delivers some kind of patch to all clients, even then be wary about servers on older versions (1.16.5 and older). It is possible that older versions of Minecraft could be affected as well, essentially any version of minecraft which uses Java 8 could potentially be affected. If you play on these minecraft versions, ABSOLUTELY AVOID PLAYING ON ANY PUBLIC SERVERS, as your computer and personal information could be at risk. This exploit is known to exploit all versions of Minecraft 1.12.2 up to Minecraft 1.15.2, regardless of vanilla/modded status, on both the server and client. There is still a chance that malicious actors could lag your game/servers on these versions, but for the most part playing on these versions should be OK. Both Clients and Servers alike are affected by this.įortunately, modern versions of minecraft (since 1.16 - 1.18) are spared the worst effects of this exploit from what I know.

This means that a malicious actor could steal your passwords/session tokens from ram, install viruses etc on your computer.

Yes, you read that right- a chat message. The exploit in question allows for RCE by means of sending a malicious chat message. (I suspect they will, but that cannot be guaranteed yet.) Mojang has not yet addressed this at time of posting, it is unknown if they will retroactively patch older MC versions or not. You should avoid playing on public Minecraft servers until this vulnerability is patched on the respective Minecraft version you play on. There is a very serious exploit that has recently been found in Minecraft (as of Dec 9 2021) that affects nearly every version of the game, both modded and vanilla. Important information for everyone who plays Minecraft (Java Edition) multiplayer:
