CWE: CWE-502 \u2014 Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid.

Code:
	public void processPacket(EntityPlayer player) {
		MovingObjectPosition box = FMLClientHandler.instance().getClient().objectMouseOver;
		if (box == null) {
			MainProxy.sendPacketToServer(PacketHandler.getPacket(DebugTargetResponse.class).setMode(DebugTargetResponse.TargetMode.None));
		} else if (box.typeOfHit == MovingObjectPosition.MovingObjectType.BLOCK) {
			MainProxy.sendPacketToServer(PacketHandler.getPacket(DebugTargetResponse.class).setMode(DebugTargetResponse.TargetMode.Block)
					.setAdditions(new int[] { box.blockX, box.blockY, box.blockZ }));
		} else if (box.typeOfHit == MovingObjectPosition.MovingObjectType.ENTITY) {
			MainProxy.sendPacketToServer(PacketHandler.getPacket(DebugTargetResponse.class).setMode(DebugTargetResponse.TargetMode.Entity)
					.setAdditions(new int[] { box.entityHit.getEntityId() }));
		}
