#Minecraft 1.11.2 keeps crashing Patch#
To patch these versions, you will need to download this file (right click -> save link as) to the working directory where your server runs - the root / directory in your file manager. If you are running Minecraft Vanilla (official) version 1.17 or higher, simply add -Dlog4j2.formatMsgNoLookups=true to your JVM arguments. We are running the latest available Java versions which do make this exploit much harder to execute, but it's still possible to exploit.
#Minecraft 1.11.2 keeps crashing update#
If there is no fix available for the version of Minecraft you are running, we can only recommend that you update your server, or do not run it until a fix is available. If you can, update your server to Minecraft version 1.18.1, where this exploit is patched.įor some older versions that likely won't receive patches however, please carefully read the information below to determine what (if anything) you need to do.
#Minecraft 1.11.2 keeps crashing software#
Generally, to ensure your server is patched, you will simply need to run the latest version of the server software you are using that is confirmed patched. Patching the server can be a little more difficult depending on the version of Minecraft you're running, but we're working to make this as easy as possible for all Nodecraft customers.

If you need manual instructions to patch your server, please continue reading below. And may not appear at all for older Minecraft versions. The exact output may differ slightly between versions, due to different log4j versions being used. Transforming org/apache/logging/log4j/core/pattern/MessagePatternConverter To verify your server has been patched, you should see some console lines near the top of your console that look something like this: Transforming org/apache/logging/log4j/core/lookup/JndiLookup We have rolled out a global patch for all affected Minecraft versions. If you are a Nodecraft customer, you do not need to do anything except restart your server. For all other launchers, please refer to their respective communities and updates for information. As of December 10th 2021, ATLauncher, MultiMC, and the FTB Launcher (via Overwolf) have been patched for this exploit. you will need to ensure these launchers have been patched before we'd recommend joining any public servers. If you are using a third-party launcher such as ATLauncher, MultiMC, etc. Mojang have released manifest updates for their launcher, so as long as you have the latest version of the launcher and restart it, your client should be automatically patched. When we refer to the "server", we'll talking about how you run the Minecraft server jar, such as through a hosting provider such as ourselves. When we refer to the "client", we're talking about how you run Minecraft on your own computer, through the Official Minecraft launcher or other launcher.
There are different things needed between the server and client, so we'll cover both here. There are a few things that you can do to ensure you are protected from this exploit.
We will continue to monitor the situation and implement any necessary patches to keep our customers and community safe. It's likely we'll be seeing more CVEs related to Log4j over the coming days and weeks, as the security community reviews its codebase and changes. At this time, there is no evidence to suggest that this CVE impacts Minecraft, but the patches we have implemented (as described below) for all Nodecraft customers would prevent the issue either way. Update: As of December 14th, a second CVE ( CVE 2021-45046) was published for an updated version of Lof4j that was released to fix the first issue. It's the second part that makes this such a serious issue, and why many public servers were shut down yesterday to ensure the safety of their players. Essentially though, with the right set of circumstances, this vulnerability allows a malicious actor to at a minimum lock up and/or crash your server, kicking all players, and at worst, execute arbitrary code both on the server and any unpatched connected clients (known as an RCE).

Exploit Detailsįor those more technically inclined, you can find full information about this vulnerability in the linked CVE. You can find some more information in the detailed blog post over on. Unfortunately, the severity of this exploit makes it really important for us to bring your attention to it, and provide steps so that you can protect yourself and your players.
This week, an exploit has been found in a very popular logging library Log4j 2, used by many Java applications including Minecraft.
