Deserialization of Untrusted Data

de.gurkenlabs:litiengine is a pure 2D free java game engine. Written in plain Java 8 it provides all the infrastructure to create a 2D tile based java game, be it a platformer or a top-down adventure.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data. An attacker can supply any instance of Serializable to MessagePacket and it would deserialize it without any checks. This could allow a remote attacker to execute arbitrary code if the classpath contains vulnerable serializable classes.

How to fix Deserialization of Untrusted Data?

Upgrade de.gurkenlabs:litiengine to version 0.5.1 or higher.

Insecure Randomness

de.gurkenlabs:litiengine is a pure 2D free java game engine. Written in plain Java 8 it provides all the infrastructure to create a 2D tile based java game, be it a platformer or a top-down adventure.

Affected versions of this package are vulnerable to Insecure Randomness. The client IDs in ClientConnection are sequential. This easily allows an attacker to spoof another player's ID.

How to fix Insecure Randomness?

Upgrade de.gurkenlabs:litiengine to version 0.5.1 or higher.

Improper Input Validation

de.gurkenlabs:litiengine is a pure 2D free java game engine. Written in plain Java 8 it provides all the infrastructure to create a 2D tile based java game, be it a platformer or a top-down adventure.

Affected versions of this package are vulnerable to Improper Input Validation. The validate method of litiengine/src/de/gurkenlabs/litiengine/net/messages/MessageHandler.java is not abstract. This means that a subclass of ClientMessage will accept any message (as long as it's not null) by default if the developer forgets to implement validate.

How to fix Improper Input Validation?

Upgrade de.gurkenlabs:litiengine to version 0.5.1 or higher.
