Found in base branch: master

Vulnerability Details

SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization. Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization. We recommend upgrading to version 2.0 and beyond.

CVE-2023-2976

Vulnerable Library - guava-30.1.1-jre.jar

Guava is a suite of core and expanded libraries that include utility classes, Google's collections, I/O classes, and much more.

Dependency Hierarchy:

  • nukkit-1.0-SNAPSHOT.jar (Root Library)
    • ❌ guava-30.1.1-jre.jar (Vulnerable Library)

Found in base branch: master

Vulnerability Details

Use of Java's default temporary directory for file creation in FileBackedOutputStream in Google Guava versions 1.0 to 31.1 on Unix systems and Android Ice Cream Sandwich allows other users and apps on the machine with access to the default Java temporary directory to be able to access the files created by the class.

Even though the security vulnerability is fixed in version 32.0.0, we recommend using version 32.0.1 as version 32.0.0 breaks some functionality under Windows.

Found in base branch: master

Vulnerability Details

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. The SniHandler can allocate up to 16MB of heap for each channel during the TLS handshake. When the handler or the channel does not have an idle timeout, it can be used to make a TCP server using the SniHandler to allocate 16MB of heap. The SniHandler class is a handler that waits for the TLS handshake to configure a SslHandler according to the indicated server name by the ClientHello record. For this matter it allocates a ByteBuf using the value defined in the ClientHello record. Normally the value of the packet should be smaller than the handshake packet but there are not checks done here and the way the code is written, it is possible to craft a packet that makes the SslClientHelloHandler. This vulnerability has been fixed in version 4.1.94.Final.
